The Ultimate Guide to the 18 Types of Engineering

Many types of engineering exist. I want to discuss all the types of engineering together so you can better compare and contrast them.

To do this, I’ll go into detail over each field and give my thoughts. On the whole, I want to shed light on the amazing world of engineering.

As a teenager growing up, I had electrical engineering as my main choice for my college major. But, I did consider many other types of engineering as well.

For example, computer, chemical, and nuclear engineering all fascinated me too. But, my interest in electricity won over. In due time, I ended up becoming an expert you could call it in electricity.

To that end, no matter your interest, one of the types of engineering will suit you. As I go over the 18 main types of engineering, look for a field that sparks your interests.

I’ll discuss the work done in these different types of engineering. Then you’ll better learn what engineers do.

So, you can choose a field for your college major. Or, maybe you find a career or business you can switch into.

This will help you answer the question “Should I be an engineer?

Also, you can simply learn more about all types of engineering. Even learn some of the best engineering skills for the real world.

By and large, knowledge never hurts and will only benefit you. Not like overeating, where your stomach hurts from eating too much food.

For this reason, I love to learn about anything and everything. I want to absorb as much information I can like a sponge.

Subfields for All the Types of Engineering

As we go over the many types of engineering, I’ll try to drill into each field the best I can. Keep in mind, each field includes many subfields that cover many specialties.

You can see how the number of subfields can become overwhelming. Simply take a step back and look around you.

Everywhere you look you’ll see technology in many forms. Almost each of these technologies requires an engineering specialty of its own.

As a result, I can’t list all types of engineering. Even if I tried, I’d fail.

So, I’ll only focus on the main types of engineering. I’ll then drill into the sub-specialties I find important.

Limitations With Describing the 18 Types of Engineering

Before we get started, you need to know overlaps exist in these 18 types of engineering.

For example, some people think materials engineering is chemical engineering. While others think materials engineering is a subspecialty to chemical engineering. Then some think both have no relation together.

You can’t win. Frankly, though, it doesn’t matter in the grand scheme of things.

Who cares if a field is a subspecialty to another field. I view all fields as a form of engineering at the end of the day.

In any event, I’ll do my best to go over what I find important for this discussion. Equally important, I’ve thought over how to break out the different types of engineering.

I titled each field to how you’d find them in most universities.

This way, we can skip over confusions on how to classify a field. As well, I can give more attention to meaty subspecialties.

Keep in mind, some subspecialties run deeper than some main fields in exposure to the public. For this reason, I want to give certain types of engineering more attention.

Now, if you don’t agree with my breakdown, I won’t take any offense. Shoot me a message and I’ll amend my list if you give me a compelling enough reason.

In the end, I want you to learn about the amazing world of engineering. Also, you can even learn to apply how engineers think to your daily life.

Without a doubt, a great tool to help you advance in life. You can gain many life tools from the engineering world.

Enough talk. Let’s get started now.

I’ve listed the 18 types of engineering below in alphabetical order. Also, I’ve added a table of contents to help you instantly jump to any field you like.

This way you can find the types of engineering that interest you the most. Or, scroll down and learn about each field one by one.

#1 Aerospace Engineering

aerospace engineering jet in sky

“Boldly go where no one has gone before”, the famous quote from the beloved TV series Star Trek. I find this quote fits perfectly with the aerospace industry.

In aerospace engineering, you work to drive the world forward. You go where no one has gone before.

“Aerospace” we define as our pursuit to fly in Earth’s atmosphere and beyond. Think of planes, jets, helicopters, drones, and even rockets and spaceships.

You can thank these engineers for allowing you to fly from America to Europe in less than 10 hours. Versus only 100 years ago or so, where it took 6 weeks of sailing in turbulent oceans.

So, anything that relates to flying fits under this branch of engineering. In other words, aerospace engineers work to design the best flying machines.

Not to mention, their work also includes designing satellites and missiles. In general, these engineers work to fight the force of gravity to keep their designs above ground.

What’s more, with a degree in aerospace engineering you can even call yourself a “rocket scientist”. How cool is that?!

With this flashy title, you can also choose from one of two categories for a subspecialty. Aerospace engineering has two main subfields.

Aerospace Engineering Sub Fields

1) Aeronautical: design and development of aircraft. Think of airplanes and jets, gliders, and helicopters. Crafts designed to fly inside of Earth’s atmosphere.

2) Astronautical: design and development of space-bound crafts. Think of NASA and Space X, who want to explore space and leave Earth in the rear-view mirror.

Today, we live in the infant stages of aerospace engineering. Even as we fly hundreds of people over oceans in gravity-defying machines. For this reason, I’m excited to see where we go from here.

We have a lot of room for improvement. We’ve only touched the surface of what we can do off from land.

Without a doubt, it gives me the butterflies when I look up into the sky and think of all the possibilities.

  • Space exploration: sending humans to far corners of our solar system. While sending robots beyond our solar system limits, to explore.

#2 Agricultural Engineering

agricultural engineering tractor working the farm

A lot goes into our favorite foods we love so much. With the number of mouths to feed today, we can’t plant a seed and hope for the best.

Today we tackle agricultural problems head-on. Big smart machines run the farms of today.

Think of the big-wheeled tractors combing through the cornfields methodically. They move slowly yet precisely like creatures that own the land.

Seeing these machines shows how much we’ve advanced as humans. We no longer plant one seed at a time by hand.

With that said, farming I would classify as one of the oldest trades in human history. Only in recent decades did farming transform into a high-tech large-scale operation.

Farming and Farmers Today

Farming became very efficient because of modern tech. As a result, we now have farms producing crops at mass scales to feed growing populations.

I could endlessly watch machines pick fruits and vegetables on Youtube. Seems like I’m watching a Sci-Fi future terminator robot who loves to farm.

All in all, agricultural engineers work to make farms run better. A lot of the progress comes from machines.

That said, existing machines can always become more efficient. They can plant seeds faster, better maintain crops, and more efficiently harvest crops.

Our livelihood relies on agriculture. So, with a growing population, the demand for greater and better crops will only increase.

I believe farmers make the backbone of countries. With this in mind, the more help they receive, the stronger economies can become.

Climate Change and Farming

Humans need food to survive. But, what happens when the climate changes? When farms yields drop, people will starve.

Crops need a certain environment to grow. With a changing climate, agricultural engineers need to recreate ideal growing environments.

I worry about our crop yields when I see where climate change can take us. But, even without human involvement, our climate will naturally change.

As a result, we need to monitor crops to prevent huge losses. We have too many mouths to feed today.

The process of placing food on your table includes many hidden and difficult steps. Many pieces to the puzzle even I take for granted when I go grocery shopping.

So, on top of designing machines, agricultural engineers modify and augment the environment. They do this to improve conditions for both animals and crops.

For example, think of water runoff patterns on fields. Also, how airflow travels in barns. This all requires planning and designing.

Secondly, crops have many enemies. This includes weather changes, insects, lack of soil nutrients, and so on.

In short, the better work farmers can do, the better food we’ll eat in the comfort of our own homes.

I believe climate change will usher in a new wave of advancements in all types of engineering. This change will come fast in agricultural engineering.

Humans all need food to survive. While today’s crops need a certain temperature to grow.

  • Selective breeding: rapid iteration selective breeding for livestock. This will breed healthier and stronger future animals.
  • Manmade closed ecological systems: crop ecosystems where everything becomes recycled. Think of a space station where recycled urine turns into drinking water. Some call it gross, I call it efficient.

#3 Audio Engineering

audio engineering mastering and producing music

I listen to a lot of music. But, I rarely think of the sound production of the music.

Still, I always enjoy what I’m listening to as I bob my head to the beat. So, I know a lot of work went into the sound production.

I can thank audio engineers for this. Audio engineers, or sound engineers, work on sound as their title implies.

They work on the technical side of recording, mixing, and reproducing sound. I view them as modern-day high-tech Mozart figures.

In short, think of your favorite band. More than likely an audio engineer put together their music to make it sound perfect.

Now, think about a recent concert you went to. Think of how the sound carried over to you effortlessly.

Even the sound of tens of thousands of loudly cheering fans doesn’t muffle the sound. If you have muffled sound at a concert, you’d never attend again. Especially since tickets can cost upwards of $200.

All in all, you’d think cranking up the volume on powerful speakers would do the trick at a concert. But no, much more goes into sound production than turning a nob.

You hear an amazing sound even standing in the back row because an audio engineer did their job well.

Audio Engineering Info Nuggets

Cool types of jobs in this field

  • Live sound engineer: blend and balance many sounds together at a live event. Think of concerts. This will ensure both the performers and audience hear what they need to hear.
  • Studio sound engineer: mastering the perfect sound for a music album in a studio. So, balancing and adjusting sound sources, using audio effects, mixing, and so on.

Amazing work done in this field

  • Wireless headsets: small wireless headsets that deliver amazing sound quality. The sound quality doesn’t even suffer in loud areas.
  • Surround sound: surround sound inside of the comfort of your own home. Digital audio systems replaced analog systems to deliver you a theatre experience.

Interesting future work in this field

  • Smaller devices: delivering higher resolution sound on smaller devices. Larger isn’t always better. So, the trend to build smaller and lighter electronics will continue.
  • Streamed music: creating the best sound quality for streaming music. This includes streaming music from your smartphone to wireless speakers. I see this as a great convenience with everyone owning a smartphone these days.
  • Talk technology: advancing voice recognition technology we see in most cars today. Also, adding audio for silent electric cars. Think of artificial engine sounds that would match your driving patterns.
  • Wireless technology: improving wireless technology by reducing the number of cables and connections.
  • Concert equipment: making large audio systems lighter, smaller, and more powerful. Think of the big clunky music equipment you see at concerts. This equipment requires multiple trucks to haul everything around from venue to venue.
  • Video game audio: improving video games with livelier more real-sounding audio.
  • Bone conduction technology: sounds Sci-Fi. Listening to music, not through your ears but the bones of your skull.
  • How we perceive sound: dampening sound. So, improving acoustics to offer better privacy in an office setting for example. You hear less noise when near others.

#4 Bioengineering

bioengineering designing prosthetic implants for human body

“Bio” in Greek means life. So, you can quickly infer that in bioengineering you design and build around life.

I must say, I’ve always loved how movies depict the merging of man and machine. I see it as the natural next step for humans. Human evolution accelerated through robots and machines.

Now, a bioengineer, or also called a biomedical engineer, may not build deadly cool looking terminators. But through the decades, bioengineers have transformed human life with their work.

We inch closer to becoming half man and half machine. I wouldn’t complain.

In short, bioengineers solve biology problems. So, they create solutions for health-related problems to improve human life.

Think of prosthetics, medical devices, drug delivery, and the list goes on. Our great advancements today in healthcare have come through bioengineering.

Next time you visit the Doctor’s office, look around. Look at the equipment and study the medical protocols.

Whenever I want medical treatment, I not only want the best Doctor, but I want the best facility. You need both to get the best treatment these days.

A doctor alone will only get you so far in your treatment. Frankly, you won’t get far at all without modern engineering.

Bioengineering Scope Goes Beyond the Medical Field

In bioengineering, you don’t only deal with humans and the medical industry. The work crosses over to plants and even much smaller organisms too.

Think of the many foods you buy and eat. You may have come across a “GMO” label on your favorite food at the grocery store.

GMO, or Genetically Modified Organism, we define as modified foods. These foods we can’t create through regular breeding. Also, they don’t exist in nature.

So, a bioengineer creates these new foods using enzymes and living cells.

You can now see the vastness of this field of engineering. Overall, I attribute a lot of the good health of myself and loved ones to great doctors. But, more so to bioengineers.

To put it another way, certain types of engineering have disrupted human evolution. Bioengineers I view as one of those fields.

They’ve transformed humans from only flesh and blood into superhumans. To demonstrate, we modify genes, heal faster, allow double leg amputees to walk, and so on.

  • Biomechanics engineer: designing and developing products that help with body motions. For example, artificial heart valves and joint replacements.
  • Genetic engineering: improving life and reshaping humanity through genetic engineering. We manipulate and modify genes of microorganisms, animals, and plants.
  • Medical imaging: designing image devices to better see inside the human body. Think of your typical X-ray for example.

Amazing work done in this field

  • Wearable tech: the devices that become a part of us, that help improve the quality of our lives. Think of a glucose monitor for a Type 1 diabetic that monitors blood glucose in real-time.
  • X-ray machines: before most every procedure, doctors take x-rays. I would certainly want an x-ray before I’m cut open and operated on.
  • Nanotechnology: advancing nanotech to better treat and eliminate diseases, disabilities, and illnesses.
  • Robot surgeons: the improvements in surgical procedures I attribute mainly to robots. We humans have limitations with our sight and touch. Robots have greatly enhanced our senses and enabled us to safely do so much more.

Interesting future work in this field

  • Improved tissue restoration: creating artificial skin and cartilage that rivals the real thing. Imagine the number of athlete careers prolonged through artificial tissue.
  • Body implants: improve implants to work better inside the human body. Creating something the body won’t reject. In other words, allowing you to avoid taking hundreds of pills to support an implant.
  • Nanorobots: fighting diseases with nanorobots. This would end harmful procedures like chemo for cancer. Nanobots would deliver drugs, heat, or other substances to specific areas in the body.

  • 3D printing: printing human organs with a 3D printer using biomaterials. This way, people won’t die as they wait for a new kidney.
  • Prosthetics: develop advanced prosthetics. I always think of robots merging with humans to create bionic humans. Now, think of a robotic leg surgically attached to a human. This would make a human superior in every way imaginable compared to other animals.
  • Brain-machine interface: humans uploading data from a machine to their brain. Also, the reverse of humans downloading data from their brain to a machine.
  • Genome editing: eliminating bad genes. This would reduce the number of deadly diseases and illnesses. Also, it would create a path to superhumans.
  • Robotic exoskeletons: helping the ill and elderly who have muscle weaknesses. Also, this would help healthy humans perform better in certain jobs. Think of jobs that require heavy lifting. Who wouldn’t want to have four times the strength?
  • Medical imaging: improving medical imaging for greater accuracy in image-guided surgeries.
  • Bionic humans: physically leveling up humans. Think of how engineering can increase the average human running speed.

Also, bettering pro athletes. Think of the force generated by Zion Williamson’s vertical jump. Bioengineering can reduce Zion’s risk of injuries. Thus, prolonging his NBA career.

#5 Chemical Engineering

chemical engineering discovering new materials

Synthetic things rule our world today. Some call most parts of human life artificial.

Simply look around you. The materials in your car, TV, iPhone, basketball, and so on were not found in nature.

These materials were not dug up from underground or extracted from far corners of the globe. Humans made these materials inside of a lab.

More than likely, a chemical engineer spent countless months and even years perfecting a material. I’ve oversimplified the process, but you get my point.

So, a chemical engineer works to discover new materials. They engineer chemicals and chemical processes to create raw materials for different products.

As well, they improve existing materials. Think of plastics, medicines, pencils, and the list goes on. All types of engineering benefit from this work.

Engineering New Materials to Constantly Make Improvements

Chemical engineers use engineering and chemistry to turn raw materials into usable products. So, it becomes clear how we can always improve existing products.

We can make materials stronger, lighter, cheaper, and safer for the environment. Every frustration you’ve had with a material can become a future engineering project.

  • Why did my tool handle break off so easily?
  • How to prevent my iPhone screen from cracking from a 1-foot drop?
  • Why does my windshield crack so easily when struck by a pebble when driving?

I can go on and on with things chemical engineers can work on. If you can’t think of anything, go walk into your favorite store and look at products.

The work of chemical engineers leads to a pursuit with no end game.

To summarize, chemical engineers take what nature provides and engineer molecular structures and reactions. They scale creations from the lab to manufacturing scale for use in the consumer world.

Chemical Engineering Info Nuggets

  • Plastics: everywhere you look you see plastic. It has become part of modern-day life today.  Many products wouldn’t exist today if not for plastic.
  • Fertilizers/pesticides/herbicides: chemical fertilizers provide crops nutrients to grow and flourish. This allows farmers to feed a growing population. Also, using pesticides and herbicides to protect and make food even better.
  • Electrical generation from fossil fuels: refinement of fossil fuels for electrical generation processes.
  • Computer chips: turning silicon into a semiconductor chip. Now, today most every electronic device uses silicon.
  • Food: humans engineer many foods. For example, we all love peanut butter. John Kellogg developed a method to prevent oil separation with peanuts.
  • Fuels: refining high-quality gasoline and jet fuel for machines. Also, converting natural gas to gasoline. In turn, this fuel powers global economies to innovate in every industry.

Interesting future work in this field

  • Improved pollution control: creating products that don’t pollute in the manufacturing process. Also, creating products we can easily recycle.
  • Improved battery technology: advancements in battery tech. This will move us faster away from fossil fuels. So, we need to increase battery life and make batteries safer and lighter.

  • Food: improving food processing to meet the increased demand of a growing population.
  • Purifying water: chemical water treatment plants already give fresh water to many people. Now, scaling water treatment to meet the demand of a growing population.
  • Renewing civic infrastructure: think of bridges, roads, water systems, electric grids, and so on. Cities would save a lot of money by only maintaining these structures versus building them from scratch. So, inventing better and newer compounds that have greater strength and can regenerate.
  • New fuel sources: making air and space travel cheaper. Also, reducing the carbon footprint of these modes of transportation.
  • Nuclear fuel recycling: converting bomb-grade uranium from missile warheads to low enriched uranium for nuclear plants.
  • Reversing climate change: improving green energy systems and rebuilding damaged ecosystems. Also, protecting existing ecosystems using synthetic materials.
  • Self-healing materials: think of concrete that no longer needs patching after cracking. The concrete heals its own cracks. So, less maintenance required.

#6 Civil Engineering

civil engineering constructing building and placing structural foundations

Look around you when you drive through any city. You’ll see roads, bridges, tall buildings, subways, homes, stadiums, and much more.

Civil engineers designed all these things we’ve grown accustomed to.

They designed and oversaw the construction of all modern-day cities today. Also, the cities from centuries ago. Their work shapes the environment we call home.

This makes civil engineering one of the oldest fields of engineering. It dates to when people first began shaping their environment to best suit their needs.

Without them, we’d still live in jungles and caves. To that end, more cities sprout around the world because we love cities.

Also, without infrastructure, the other types of engineering would never have thrived. We need a roof over our heads, a road to travel on, and buildings to operate in before we can think outside of the box.

With that said, I would say two main types of civil engineers exist. Those who design, and those who watch over the construction in the field.

Both require a special skill set. But, many overlaps exist.

I’ve seen many engineers who complete a design and then go in the field to overwatch the construction. I believe to maximize your potential, you need a mix both.

Moving along, we can now break out the different subfields of civil engineering.

Different Subfields of Civil Engineering

  • Construction: managing projects in the construction phase. Making sure the tall buildings or new roads meet the design and building codes.
  • Geotechnical: dealing with earth materials, such as soils and rocks. This helps other engineers better design tunnels, mines, structural foundations, and so on. For example, building a skyscraper requires you to know the soil type for the foundation. Without this information, the skyscraper would fall over.
  • Structural: designing high strength structural foundations that’ll withstand earthquakes, high winds, and floods. Every manmade structure you see standing tall had a foundation designed for it.
  • Transportation & Traffic: designing highways, railways, airfields, and other transportation structures. Also, all those red lights in cities you hate, all require planning and design to keep traffic flowing.
  • Water resources: improve the quality and quantity of fresh water. Think of water treatment and wastewater treatment plants that produce fresh drinking water.

Now, you can better grasp and appreciate the large scope of the civil engineering profession. Many subbranches in civil engineering exist.

I view civil engineering as the largest field compared to the other types of engineering. Even more impressive, all the subbranches of this field tie together perfectly.

For instance, think of the structures you enjoy taking selfies in front of. Many sub-sectors of civil engineering built these structures together.

Even the simplest structures require a huge team effort that often goes unnoticed. For this reason, I’m always amazed when I walk and look around in cities.

Civil Engineering Info Nuggets

Cool types of jobs in this field

  • Construction management: inspect and manage large engineering projects. Types of projects that you’d see on the Discovery channel. Think of large bridges, buildings, stadiums and so much more.
  • Bridge engineer inspector: inspect bridges from new to old. See historic sites and view old and new engineering practices. Just don’t have a fear of heights.
  • Building demolition: using explosives to safely deconstruct structures.
  • Airports: design and build the new modern age airports of tomorrow. These airports resemble something out of a Sci-Fi movie.
  • Infrastructure planning: plan a new structure for a city. Think ahead to layout a design that may become the centerpiece of a city. Imagine planning and building a new stadium. A stadium that one day may become the centerpiece of a city’s local economy.

Amazing work done in this field

  • Burj Khalifa: the tallest building in the world standing 2,716.5 feet tall in Dubai. It took roughly 5 years and 22 million-man hours to build.
  • English Channel Tunnel: a 31 mile plus undersea rail tunnel that connects England and France. At its lowest point, the tunnel sits 250 feet below sea level.
  • Golden Gate Bridge: the iconic burnt red bridge in San Francisco. I’m still fascinated as I drive over this 8,981-foot-long 887,000-ton bridge with the ocean roaring underneath.
  • Three Gorges Dam: the world’s largest power station, with a total capacity of 22,500 megawatts. This massive hydroelectric plant in China includes 32 main generates rated 700 megawatts each.
  • Palm Islands: the world’s largest artificial island shaped like a palm tree located in Dubai. Making this island required over 32 million cubic meters of sand from the bottom of the ocean floor.
  • Great Pyramids of Giza: built before modern technology ruled the world. The huge size, near-perfect geometric dimensions, and the surrounding mystery fascinate me. I love the Giza pyramids. Even more so considering their construction may predate 2550 BC according to new findings.

Interesting future work in this field

  • Future structures: building larger structures in heavily populated cities all across the globe.
  • Rehabilitating aging historic structures: think of your favorite engineering projects today. One day they’ll require major work to keep them up and open.
  • Underground structures: designing and constructing underground in growing and dense cities. Think of tunnels, subways, and even building compounds, built underground.
  • Roads and highways: building and modifying roads and highways to accommodate self-driving cars.
  • 3D printers: using 3D printers to reduce costs and shorten build times in construction. We can build homes today using 3D printers, but not at scale and cost-effectively.
  • Nanotechnology: use of nanotech to strengthen materials and soils to better maintain structures. For example, using nano-iron in concrete to strengthen it.
  • Virtual and augmented reality: to virtually analyze a proposed structure before construction begins. This becomes a great way to spot potential issues and modify designs.
  • Sustainable designs: building smart buildings with sensors and other tech. This will reduce energy usage and help protect our environment.

#7 Computer Engineering

computer engineering designing hardware chips

Most everything today involves computers. More than likely you’re reading this post on a computer you store in your pocket. Your smartphone.

Clearly, this field of engineering advances at rapid speeds. As a simplistic example, look at your pocket computer, smartphone.

It has over 100,000 times more processing power than the Apollo 11 computer that traveled to the moon. This always boggles my mind.

So, with such rapid advancements, all other fields of engineering benefit too. Everywhere I look today, I see computers running the show.

That said, in computer engineering, you deal with both hardware and software. We’ll go over them both.

Hardware Engineering Versus Software Engineering

Hardware engineering: designing and developing the many components of a computer. These components include processors, memory devices, network devices, circuit boards, and much more.

These engineers make sure all the computer components properly work together. As well, they analyze computers to find the best way to improve existing designs.

So, anything you can physically touch you can classify as hardware.

Software engineering: writing computer software to make a computer complete tasks and operations. These tasks and operations do work in almost every field:

  • Managing a power grid
  • Designing video games
  • Controlling self-driving cars
  • Controlling robots in an assembly line
  • Guiding aircraft

Further, I’ll discuss software engineering more in-depth in its own section below.

So, what can we conclude? The end goal with computers comes down to making them faster and more powerful. This then allows us to do more amazing things beyond anything we could ever imagine.

In fact, I work with all types of engineering professionals. I see them all use engineering software.

With this in mind, all types of engineering would suffer greatly without software. For example, if I had to do engineering studies by hand my work would progress at a snail’s pace.

Besides, a lot of electrical equipment today relies on the digital world. We simply need software to operate in today’s complex world.

#8 Electrical Engineering

Seeing pictures of Nikola Tesla as a kid won me over with electricity. All his experiments frankly looked beyond cool.

Now today, we can’t live without electricity. Every part of society highly depends on it.

Imagine your life without light, smartphones, internet, refrigerated foods, power, and so on. Sounds scary, right? Agreed. I couldn’t recognize life today without electricity.

As I’ve shown, electricity makes our world go around. We need electricity to create everything we have today, from modern roadways to phones.

Without electricity humans as a society would no longer advance. We would devolve and go backward in time, setting us back decades.

Even losing power for a week, life, as we know it today, would instantly change.

Electricity fascinates me. Think of how we’ve harnessed electricity through experimentation with conductors and magnets. Amazing, but at the same, it makes us humans very vulnerable.

With this in mind, let’s return to talking about electrical engineers. Electrical engineers work on many things. Let’s go over some of the subfields:

  • Communication
  • Controls
  • Electronics
  • Power

So, electrical engineering includes many sub-branches. After all, every area of life today relies on at least one component of this field.

Different Sub Fields of Electrical Engineering

  • Communication: design and development of communication equipment and systems for transmitting data. Think about how you instantly call people on the other side of the globe. Or, how you ping satellites using GPS every day when you drive places.
  • Controls: making systems work efficiently and become more predictable. We do this by ensuring equipment operates how we want through control logic.
  • Electronics: design and development of electronic components. For example, transistors and semiconductor devices.
  • Power: generating, transmitting, and distributing power. Now today, we also heavily focus on renewable energy as we step away from fossil fuels.

Overall, I see the future of electrical engineering jobs growing. Even with automation, these subbranches will all continue to thrive.

Electrical Engineering Info Nuggets

Cool types of jobs in this field

  • Power grid: manage the power grid. To the surprise of many, the biggest machine on Earth is the U.S. power grid. A very complex yet outdated electrical system that needs constant attention.
  • Signals: growing demand for signal processing with everyone connected to a wireless device. Also, the design of new tech in this medium with more satellites fired into space.
  • Renewable energy sources: connecting renewable energy sources to and off the power grid. This will help states like California. California has the bold goal of 100% renewable energy by 2045. A lot of demand exists.
  • Industrial automation: more factories today use machines for their assembly work. Think of car assembly lines in factories. So, helping in the transition from human labor to machine automation.
  • Electronics: look around you in your home and office. Everything everywhere uses electronics. We depend on electronics as cavemen depended on fire.

Amazing work done in this field

  • Satellite communication: a satellite in space receives and sends signals from and to Earth. I’m fascinated by how these satellites travel 7,000 miles/hour at a height of 22,000 miles above us.
  • U.S. Power grid: the biggest machine on Earth. A delicate balance to provide power to millions and millions of customers on demand. This makes you appreciate the power grid, given how little downtime we experience.
  • Microprocessors: the most central part of a computer. Look around you and you’ll find computers everywhere doing what no humans could ever do.
  • Electric motors/generators: they give cities life. Without motors and generators, we wouldn’t have electric power, running freshwater, and so on.
  • Transformers: they step up or step down a voltage in a power grid to deliver your power. Without transformers, our U.S. power grid would not work. Also, your favorite electronic devices would not work either.

Interesting future work in this field

  • Improved power grid: many parts of the U.S. power grid have aged and need major work. Also, renewable energy has become another curveball for the existing power grid. The power grid needs improved infrastructure to handle new renewable power sources.

Renewable power sources do not generate power consistently. We have wind sometimes, sometimes we don’t. The sun comes out sometimes, and other times the sun remains hidden behind clouds. In contrast to a coal plant, that burns coal consistently every hour of the day. This inconsistency creates problems for today’s power grid.

  • Advanced robotics: look no further than your favorite Sci-Fi movie. Robots over time will become more and more a part of our everyday lives as we move into the future. Maybe not as a killer Terminator played by Arnold, but think of all the automation going on around you today.
  • Nanotechnology: solving problems at a micro-level. Problems begin at the smallest level, and one day we can work and fight at this micro-level.
  • Smart grids: using smart devices with the power grid and renewable power sources. This will save money and help us better manage the power grid. Our power grid is too complex today for humans to oversee alone.
  • Bulk energy storage: improving energy storage. Think of batteries. Imagine a Tesla car with a 1,000-mile range. Now, imagine storing excess wind power generation in a battery because of extra windy days. This would give us power to use months from now.
  • Electric cars and planes: electric cars will one day rule our roads. Then soon thereafter planes will no longer burn jet fuels.
  • Engine efficiency: improving the efficiency of engines. Our modern world revolves around motors and generators. They allow us to switch on lights at home and drink fresh water from our sink.
  • Renewable energy: new and improved renewable energy sources. This will allow us to more quickly move away from fossil fuels. In turn, we’ll see greater advancements in all types of engineering through clean energy.

#9 Environmental Engineering

The world population grows, but natural resources remain fixed.

We humans blindly use more and more natural resources every year. Most of the time without thinking of the outcome.

For this reason, we need environmental engineers to protect the environment. To protect us from ourselves.

I would think the smarter we become as a species, the more protective we’d become over our only planet. But human greed makes some people do illogical things.

As an example, with some projects, I hear how environmentalists and even environmental engineers delay projects. Also, how they make projects more complex than needed.

As a result, many view them as an annoyance in projects.

Truth is, we’re our worst enemies.

We need boundaries to create a give and take relationship. Otherwise, even the noblest engineering projects can over time destroy a region.

So, we need environmental engineers to guide the many types of engineering. I sometimes view it as a parent and child relationship.

To explain, we don’t always get along. In fact, many times the relationship becomes very rocky. At the end of the day though, we need the overwatch and discipline.

Protecting Earth by Taking Action

Environmental engineers create boundaries and pave the way for longterm human growth. We can’t continue to kick the can down the road and hope future generations will fix our problems.

For that reason, we need to act today. Environmental engineers do good by slowing pollution and protecting limited natural resources.

With a growing population, the human footprint will continue to grow. We’ll need more power, more freshwater, larger infrastructures, and so much more.

Many issues need attention. Flip on the news and you’ll see climate change, rainforest fires, plastics flooding the oceans, and so on.

An environmental engineer will work through these issues to help protect our planet. They’ll analyze the impact of work from other branches of engineering.

The goal becomes to identify potential problems and to prevent them. Making checks on designs and to supervise ongoing projects.  Also, doing the design part of projects that lead to environmental protection.

Cool types of jobs in this field

  • Air quality control: maintaining air quality as infrastructures and populations grow. Basically, the goal to keep solids, liquid particles, and certain gases out of the air.
  • Water/wastewater: proper design of dams, diversion structures, sewer lines, and so on. This will give us clean power from hydro stations, without causing too much damage to the surrounding area.
  • Environmental remediation: cleanup strategies of project sites after construction. This includes managing groundwater contamination, ocean water contamination, and so on.

Amazing work done in this field

  • Clean water supplies: getting fresh water to millions of people all around the globe.
  • Managing waste to prevent diseases: many facilities produce waste in their production processes. So, containing the waste requires planning and proper design of facilities.
  • Managing pollution: monitoring pollution in air and water. Thereafter, finding solutions to reduce waste from existing pollution sources.
  • Improved waste management: reusing waste. Think of a wastewater treatment plant that purifies dirty water. The more we recycle, the better we can protect our natural resources.

Interesting future work in this field

  • Developing countries: extending environmental engineering practices to developing countries. Many developing countries need direction on how to preserve their local environments. Many of them are growing fast as they go through what America did in the industrial revolution age. This leads to a lot of pollution.
  • Water treatment: new water treatment plants that don’t use harsh chemicals to remove water contaminants. Now, UV disinfection exists, where we don’t use chemicals. But, I’m talking about a cheap and large scale system for treating water.
  • Pollution control: unified pollution and waste management protocols at scale. This way we can control global pollution together.
  • Sustainable communities: building sustainable communities that recycle their waste. This will reduce the size of landfills and keep our planet more habitable.
  • Renewable energy: managing the global transition to a green and sustainable developed world.

#10 Geotechnical Engineering

“Geotechnical” refers to geological parts of the earth. Think of soils and rocks. The Earth you walk on.

So, clearly, geotechnical engineers need to have a strong understanding of geology. This way, they can apply what they know about the Earth to the engineering world.

They examine soils and rocks. Then, they may relay their findings to structural engineers for their foundation designs. You wouldn’t want to build a half-billion-dollar structure on top of weak soil for instance.

On that note, I get soil information from geotechnical engineers too. For example, before I design a ground grid for a substation, I need the soil resistivity.

Different soils have different resistivities. As a result, the type of soil will affect how electricity travels through the land.

Without this information, I can’t accurately design a ground grid. An unsafe ground grid can kill people who work at a substation.

In summary, a geotechnical engineer analyzes the land before design work begins. Their work dictates the direction of a design.

They play a critical role in everything you see built around you today. Skyscrapers, bridges, and even your home.

Also, as important, they play a major role in what you don’t see. Think of underground construction such as subways, tunnels, mines, and so on.

The design and cost of projects greatly depend on the land. A soft ground versus hard rock will completely change the course of design. So, the work of geotechnical engineers can make or break a project.

Cool types of jobs in this field

  • Concrete and asphalt testing: in all corners of the globe you’ll find concrete and asphalt. So, you can do investigation and testing in interesting places.
  • Construction supervision: inspect subsurface conditions of materials and manage the construction itself. Inspect everything from bridges to skyscrapers to stadiums.
  • Soil inspection: inspect soil in all corners of the globe. Inspecting at depths of 10 feet and sometimes hundreds of feet.

Amazing work done in this field

  • Bridges: building large and long bridges in harsh environments. Think of the Golden Gate Bridge built almost 100 years ago. The foundation of the bridge sits underwater fighting harsh currents.
  • Skyscrapers: building taller and taller buildings in all corners of the globe. We see many of the world’s tallest buildings in Dubai, where you see desert sand as far as the eyes can see. Clearly, no limits exist on where buildings can now stand tall.
  • Coastal structures: building more structures that withstand wet and harsh ocean water climates.

Interesting future work in this field

  • Exotic construction locales: construction in exotic areas around the globe. Especially, as populations grow. Imagine building in high elevation untouched mountainous areas. Also, in sandy terrains on top of fault zones.
  • Large scale inspections: inspecting land, to build larger and taller structures in uninhabited areas.
  • New surveying techniques: advancing surveying techniques to more accurately evaluate land.

#11 Industrial Engineering

The more complex systems become, the more optimization they need.

In the past, one person in a factory would screw on a tire and glue on components and then call it a day. Very simple and straightforward work.

Today, a factory includes countless parts with hundreds of workers and machines. All these players need constant coordination. Think of a car manufacturing plant.

You have robots and humans seamlessly working together. The coordinated work resembles an in-sync symphony.

All the moving parts work together in an orderly fashion. Without a hiccup, all the parts of a car join together. It seems like magic.

A complex process, leading to a masterpiece of engineering coordination. I view the masterpiece as the car assembly process, not the result of the car.

To that end, an industrial engineer designed and simplified the assembly process. They made the production efficient and cost-effective.

How Industrial Engineers Work

The work of industrial engineers touches every industry and all types of engineering. Every industry includes its specific complex processes.

What looks simple on the outside, includes many moving parts on the inside. Look no further than the slim rectangular shaped phone inside your pocket.

In brief, to get from point A to point B in product manufacturing, you need to complete certain processes. A process can include people, information, money, equipment, materials, and so on.

Now, an industrial engineer works to simplify complex processes. For example, they’d drop step 5 and merge steps 10 and 11.

As a result, a process becomes more efficient and a company would save millions of dollars.

To illustrate this, think of how production would speed up. A product now gets made in 10 days versus 30 days and without any expensive hiccups.

In summary, an industrial engineer optimizes processes. They drop unnecessary steps and add beneficial steps. They simulate scenarios to find how best to get from point A to B.

As I see it, industrial engineers make lemonade from lemons. Simple systems take great effort to build.

Industrial Engineering Info Nuggets

Cool types of jobs in this field

  • Process engineer: all types of engineering and industries today have become increasingly complex. As a result, industrial engineers have many options on companies to go to, to optimize systems.
  • Production supervisor: find your favorite industry and improve the production line. Supervise the work, and find ways to improve existing and new processes.

Amazing work done in this field

  • Improving human efficiency in work: work can always become more efficient. Simply look at Amazon with how they’ve optimized their entire supply chain. As a result, they can provide near-overnight delivery on all online orders.
  • Streamlining a supply chain: when Tim Cook replaced Steve Jobs at Apple, he separated retail from inventory. He optimized Apple’s assembly line where they make their products in China. As a result, he reduced Apple’s overhead costs while keeping up with consumer demand.

Also, he knew how to fight back against Google and Samsung to keep Apple winning. He constantly tweaked Apple’s supply chain. This led to increased efficiency in their production.

  • Moving assembly lines: Henry Ford invented the moving assembly line. He did this to scale his car’s manufacturing for mass production. This allowed for cheaper and more reliable cars to hit the streets of America at scale. Later, most every other factory in America adopted his assembly line process model.
  • Merging humans and machines: this merger made processes more complex. But, humans working with machines resulted in cheaper and more reliable products. Best of both worlds.

Interesting future work in this field

  • Advanced technology: working on more complex systems as technology further advances. Also, as software takes on an even greater role in production lines.
  • Green sustainable future: improving production in the move to a sustainable and green future. We need to control pollution alongside the goal of increasing production efficiency.
  • AI and robots: integrating AI and robots into factories of all types to increase production efficiency.

#12 Materials Engineering

You hear about low carbon steel, carbon fiber, high strength steel, aluminum, and the list goes on. Many different materials exist.

On that note, every man-made product uses a specific material that best suits it.

Given that, a process does exist in selecting the best material for every product. Choose the wrong material and a plane will fall out of the sky.

In brief, material engineers select the best-suited materials for products.

Now, don’t confuse a materials engineer with a chemical engineer. Many overlaps exist, but they each play a unique role as engineers.

For starters, both types of engineers do include a lot of chemistry work. But, a materials engineer focuses on the materials themselves.

Understanding why and how a material performs the way it does. As well as studying, which material would work best for a given application.

For example, a materials engineer has the job of finding the best material to use for helicopter blades.  They’d need to find an affordable lightweight yet strong and flexible material to use.

Now, the material choice could mean life and death. So, the material selection process involves many detailed steps.

Improving Existing Products

We know a material can make or break a product. At the same time, this means we can always improve over existing products.

For example, imagine we discover or make a cheaper, lighter weight, and stronger material than aluminum. A materials engineer would then recommend this material for planes instead of the aluminum used today.

The plane would save on fuel costs due to its reduced weight and it would also become safer for passengers. A win-win.

In short, we can always improve existing products with new better materials. As well, bring new products to the market that previously had material limitations.

Material limitations exist because of some type of physical limitation. For example, think of rockets, made from aerospace-grade aluminum.

We could reduce the fuel for launch if we had a stronger yet lighter weight material. Thereafter, send more things into space.

But, until that day comes, we stick with what we have. In essence, all products in all types of engineering would benefit from better materials.

Materials Engineering Info Nuggets

Cool types of jobs in this field

  • Metallurgy: studying the physical and chemical behavior of different metals. Learn about what makes these metals tick, to then know what products to recommend them for.
  • Biomedical: studying and finding the best materials to use in the medical industry. Think of materials and tools used in surgeries, used to repair us from injuries.
  • Product engineer: ensure the manufacturing process for a given product remains on point. In other words, the manufactured product remains consistent in mass production.

You don’t want a copper wire for example to have less insulation in one area than another. The insulation must remain uniform all around.

Amazing work done in this field

  • Commercialization of plastic: using plastic in every industry. Look around your home and office. You’ll see this durable, strong, and highly moldable material used everywhere.
  • Computer chips: using silicon for computer chips. Silicon makes a great insulator and semiconductor. Thus, allowing the flow of a little electricity. In return, we get computers.
  • Airplane wings: the used material allows a cylinder-shaped object filled with humans, to safely fly over oceans. We can thank aerospace-grade aluminum for very strong yet lightweight wings.
  • Basketball: a favorite pastime of mine, that centers around a simple-looking ball. However, a lot goes into making this simple ball. The main materials for making the ball include synthetic rubber and leather. These materials give a basketball the balance of a perfect bounce with an amazing grip.
  • Biomedical devices: these devices make or break today’s advanced medical industry. Doctors and nurses need sturdy and safe materials to use inside the human body.

Interesting future work in this field

  • Advance existing products: testing new materials to improve existing products. For example, searching for lighter and stronger metals for plane bodies. This will make planes safer and more fuel-efficient.
  • Advance technology: transform industries by selecting better materials for new use cases. Many times, existing materials become bottlenecks for designs.

Again, think of planes. A stronger and lighter material would make way for electric planes. These planes could now possibly support the heaviness of batteries.

  • Nanomaterials: use of nanomaterials to makes better materials. This includes increasing strength, making lighter weight, improving temperature tolerance, and so on of materials. These new materials will lead to improved designs.
  • Environment protection: using more environmentally friendly materials in products to protect our environment. Think of what you can and cannot recycle today.

#13 Mechanical Engineering

No tech without mech. Also, referred to as the ‘mother’ branch of engineering.

I hear this a lot from mechanical engineers in a semi-joking way.

They have a point though. Most all our favorite tech wouldn’t work without a mechanical engineer involved.

I look at each of the types of engineering and I see how each of them includes moving parts. On the other hand, not all types of engineering rely on mechanical engineers.

To put it differently, who would disagree with Leonardo da Vinci who once said, “The power of water has changed more in this world than emperors or kings”. Think of hydraulic turbines that convert energy from flowing water to electrical power.

So, mechanical engineers understand how the physical world works from a technological lens. They can create things for the real world from only a simple idea.

In other words, when you have any moving parts for a product idea, you’ll need a mechanical engineer to assist you. In fact, I can’t think of any of the types of engineering that wouldn’t involve mechanical engineers.

The Demand for Mechanical Engineers

Let’s go over some products that mechanical engineers helped design.

Some product examples include robotics, HVAC, hydraulics, airplanes, and even electric cars. Now, an electric car does include fewer moving parts than a gas-powered car due to the electric motor.

Still, though, an electric car drives using a motor and wheels. So, the software simplifies the driving process. But, software alone doesn’t physically make a car move.

Hardware brings the software to life in the real world. In other words, machines merge the digital world with the real world.

Taking one step further, even designing smartphones requires mechanical engineers. For example, Apple employs mechanical engineers who do product design and sensor work.

Clearly, mechanical engineers can work in almost every industry. Every industry includes some type of machine with moving parts that need designing.

In summary, mechanical engineers tie together many types of engineering. They bring to life your favorite products.

Mechanical Engineering Versus Software Engineering

Now, some believe software will destroy the field of mechanical engineering.

On one hand, we now have started the move into the virtual world. Some subfields of mechanical engineering have shrunk because of software.

For example, the hit against the car engine industry. The emergence of electric cars and software automation has changed this space. Conversely, though, new subfields have grown for mechanical engineers through software as well.

Think of all the car factories that now have robots building cars. Robots have countless mechanical parts.

Thus, unless humans warp into the virtual world forever, the demand for mechanical engineers will remain high. I certainly still plan to live in the real world.

Mechanical Engineering Info Nuggets

Cool types of jobs in this field

  • Product design: design anything and everything that includes moving parts. Look around you as you read this. So many different products with moving parts exist.
  • Nanotech: altering materials at the smallest levels. Using this new technology in the food, energy, water, machine, and environmental industries.
  • Operate and test machines and mechanical systems: testing all types of machines and equipment. You can work on anything that interests you, from cars to rockets to large factory robots.

Amazing work done in this field

  • Ferries & Cliffhouse Cable Railway Powerhouse: built-in 1887 in San Francisco. One of the most complicated cable railway systems of its time.
  • Hydraulic turbines: designing turbines that convert the flow of water into electrical power. One of the best free sources of electrical power in the world today.

  • Airplanes & cars: every car and plane include many moving parts. A plane will naturally have more moving parts than a car. Regardless, someone needs to do the design work from the nuts and bolts level and up.

Interesting future work in this field

  • Robotics: robots of the future will interact with the physical world no different than how you and I do. This means many moving parts. Go look at the Boston Dynamics’ robots on Youtube. Amazing yet scary!

I see a future where all the types of engineering use robots in some way to advance their field. These custom robots will need the help of mechanical engineers to build.

  • Self-driving cars: these cars have sensors like eyes to navigate the roads autonomously. So, mechanical engineers would work on the radar, cameras, LIDAR, and more.
  • Future spaceships and rockets: who knows how we’ll fuel the future space crafts of tomorrow. But what we do know, these space crafts will have some type of propulsion system to fly them around. Look at your favorite Sci-Fi film. Someone will need to design these propulsion systems.
  • Motors and generators: you have the rotor and stator, with the rotor rotating. Also, the heat transfer needs consideration in the design as well. We can always make motors and generators more efficient.
  • Renewable energy: clean power sources have taken over the world. Most of these power sources have moving parts. Think of those massive white-colored spinning wind turbines, in the distance, as you drive on the highway. To make them more efficient, mechanical engineers will need to optimize their designs.
  • Ocean power tech: harnessing the power of the ocean tides to generate power. We’d need a uniquely designed turbine to pull this off though given the power of the ocean.

#14 Ocean / Marine Engineering

ocean engineering - building devices and equipment for seas and coasts

The oceans cover 71% of Earth and make up 97% of the water found on Earth. Amazing!

Even more fascinating, 80% of the oceans have gone unexplored. Knowing this, we still seek to travel to other planets in our solar system where humans have not gone before.

Ironic, considering we haven’t even explored a large part of our planet. This just shows the vastness and greatness of the small rock we call Earth.

For this reason, ocean engineers have a great role in advancing humans and all types of engineering. Their work today gives us a lens into alien worlds we’ve only read about in Sci-Fi.

All that said, ocean engineering deals with the ocean or more generally any body of water. So clearly, these engineers need to have a deep knowledge of oceans and water.

They know the types of equipment ocean type work requires. As well, they understand the many harsh realities of oceans, which they always need to keep an eye out for.

Knowing this, ocean engineers combine knowledge from many engineering fields. For example, the electrical, civil, mechanical, acoustical, and chemical fields.

This gives them a unique edge with their design work. They have a great basic background in almost all types of engineering.

To that end, the science and math remains the same, but the playing ground changes from dirt to sand and water.

Primary Work of Ocean Engineers

Designing and building equipment for offshore and coastal areas. The work of ocean engineers helps other professionals such as scientists. The scientists can then better explore and learn about our oceans.

Without the work of ocean engineers, we wouldn’t have been able to visit the remains of the Titanic 2.4 miles down in the Atlantic Ocean. Also, we couldn’t study many alien-like creatures who stay hidden on the ocean floor.

Beyond the cool equipment, ocean engineers help with booming construction near coasts. For example, they address pollution and waste disposal issues. Especially as more people now live and work near ocean coasts.

Furthermore, the oil industry operates off in the oceans too as they constantly drill for oil. The skillset of ocean engineers helps in this space as well. The work includes pollution control and design of equipment used to find and mine oil.

Ocean / Marine Engineering Info Nuggets

Cool types of jobs in this field

  • Offshore oil industry: design, construction, and maintenance of equipment for the oil industry. Innovating over existing technology, to create better equipment.
  • Offshore wind farms: installation of offshore wind farms in the oceans. Ocean engineers work to locate the best areas to install these large structures. Also, they work with other engineers on how to best install them in different ocean locations.
  • Operation and maintenance of sea vessels: handling operations onboard a tugboat, oil tanker, or even large cruise ships. You’ll have the responsibility of keeping the ship’s equipment running. Also, troubleshooting problems in real-time.

Amazing work done in this field

  • Oceanographic instruments: the invention of thousands of oceanographic instruments and devices. This has changed how oceanographers and scientists study oceans and coasts. Through these studies, we all benefit by learning how to keep a healthier Earth. Also, we better learn how to locate seafood and fossil fuels, and learn how life started.
  • Underwater travel: enabling scientists to go deeper and farther into the ocean. Also, how to stay under high-pressure water for longer periods of time. I find this amazing given the harshness of oceans. You have high-water pressure at low depths, near-freezing temperatures, and strong ocean currents.
  • Discoveries: because of ocean engineers, we’ve made many discoveries. Such as hydrothermal vents, ocean volcanoes, underwater mountain chains, and new ocean species.

Interesting future work in this field

  • Improved underwater equipment: better equipment allowing for deeper and farther ocean voyages. We can then go where no humans have gone before.
  • Protection of our waters: new designs to protect underwater environments and sealife. With a growing population, oceans need protection from humans. This includes lowering pollution and protecting underwater environments.
  • Ocean learning: learning how to use the ocean to improve life on Earth for humans. For example, by preserving sea life we learn how to improve life on land.
  • New inventions: making mining in the ocean for minerals and oils safer. Also, reducing pollution from mining.
  • Coastal structures: protecting coastal structures as sea levels rise from climate change. Think of all the homes built near ocean coasts. For example, think of the danger of homes on Florida’s coast due to the rising sea level.

#15 Mining Engineering

I think of Earth as a large gift that endlessly gives. Inside of this gift, we can find many amazing things.

For example, we can find coal, copper, iron ore, gold, and so much more. These metals and minerals all lay hidden beneath the ground unnoticed.

Given that, mining engineers focus on removing these metals and minerals from underground. Like an iceberg, the naked eye only sees a small fraction of what Earth holds.

For this reason, to mine for such things as gold, building a safe and easy to work in mine requires a special skill set. A special skill set only held by a trained mining engineer.

Work and Specialization of Mining Engineers

A mining engineer typically specializes in one type of metal or mineral, such as coal or silver. So, they master how to build mines for a specific material. Both to create a safe and productive working environment.

They specialize because of the unique difficulties presented by each type of mine. Only experience, allows mining engineers to know all the details of how to create certain mines.

Moving on, mining engineers also do many other things, such as:

  • Design and test machines
  • Come up with mining techniques
  • Brainstorm new processes for better removal of materials
  • Devise methods to store excavated soil

The end goal becomes faster, cheaper, and safer methods of material removal. All without damaging the environment too much.

For example, when miners mine, mining engineers ensure everything goes as planned. The mining engineer would do the following:

  • Check for hazardous gases in the mine
  • Make sure the drilling equipment operates properly
  • Create and maintain evacuation routes inside the mine
  • Ensure the surrounding environment remains intact and healthy

To point out, you can see how the work of mining engineers overlaps with geotech engineers.  Mining engineers investigate possible mine locations, while geotech engineers analyze soils. This shows how all types of engineering overlap in some way.

Cool types of jobs in this field

  • Inside of mines: operating and managing metal and mineral mines. Ensuring the safety of everyone working inside of a mine. All while efficiently removing as much material as possible.
  • Exploration: searching for more and better mines in all corners of the globe.
  • Tunneling: designing tunnels, since most materials remain hidden in mountains and underground. Drilling a hole in a structure without it collapsing requires careful design. For this reason, mining engineers need proper understanding of tunneling.
  • Frac sand method: using frack sand to open fractures to extract oil and gases from shale. With an increasing demand for oil and natural gas, we more often now use the frac sand method.

Amazing work done in this field

  • Mine setup: skillfully using pumps to dewater pits. Also, using dynamite to replace black powder to more skillfully and safely break rock.
  • Monitoring equipment: use of geotech monitoring equipment to predict rockslides. This allows mining engineers to quickly and safely evacuate mines before catastrophes. Many times, mining engineers use radar and ground probes to keep a watchful eye out.
  • Pollution control: creating less waste at mining sites. Also, preventing the degradation of a mined area.
  • Mine safety: using rock bolt cable bolts to reinforce deep mines. This way miners can safely go deeper to extract more metals and minerals.

Interesting future work in this field

  • Deeper mines: going deeper underground and farther into a mountainside. This way miners can extract even more metals and minerals.
  • Imaging technology: using improved imaging tech to locate and explore mines. As we travel to farther corners of the globe to mine, we’ll need better tech to locate materials.
  • Remote automated drilling: drilling without the presence of humans. A human can control the machinery remotely like a drone.
  • Autonomous haulage systems: self-driving trucks hauling mined material on to a given location. A mining engineer would organize and plan the routes of these trucks.
  • Mining processes: new methods to improve the yield of mined precious materials. Think of how we need to separate metals from rock after we extract mined materials. So, increasing the process efficiency to save more precious materials and reduce mining costs.
  • Asteroid mining: sounds Sci-Fi, but one-day asteroid mining will become a thing. A reality. We have a limited supply of metals and minerals on Earth. The next frontier will lead us to asteroids as we continue to progress as a species. How cool would that be?!

#16 Nuclear Engineering

nuclear engineering power plant using nuclear fission

Nuclear power plants have received a bad rap over the years, and some of it I understand. But, we can’t deny their positive role in society either.

Nuclear energy powers a lot of the world today, without polluting by burning fossil fuels. As well, they’ve become much safer too even when you factor in human errors.

This now brings us to nuclear engineers. Nuclear engineers’ work focuses on nuclear energy and radiation.

In other words, they focus on sub-atomic processes relating to fission and fusion. Nuclear fission produces atomic bombs, and nuclear fusion we find in the sun.

Without question, nuclear engineers work in a very impactful and powerful field. That said, a lot of their work revolves around improving existing nuclear power plants. But also, designing new and improved nuclear power plants.

With the fear surrounding nuclear energy, nuclear engineers will never reach a good enough design. A safer design always exists.

Now today, with renewable energy taking center stage, we need nuclear power more than ever. With growing populations and developed countries modernizing, the power demand will only increase.

The future advancements of all types of engineering depend on more energy. No different than when you and I need food to do all the amazing things we do as humans.

Going After Fusion Energy

Going one step further, a sub-branch of nuclear engineering focuses on the holy grail of power generation. The development of fusion power.

Fusion power powers our sun and the stars. The best limitless clean energy we could ever harness.

Fusion power could forever change our world as we know it today.

I believe advancements and failures in nuclear power helped push fusion energy tech, forward. Without it, we wouldn’t stand to inch closer to harnessing this incredible power today.

On the flip side, if the fear over nuclear power didn’t exist, maybe we’d have fusion power today.

Regardless, every day we inch closer to this unworldly power. A limitless energy source that could forever fuel our planet. Also, completely change the way we travel on Earth and beyond.

Fusion power may become the key to one day traveling deep into outer space. Sci-Fi reality never seemed so close.

Cool types of jobs in this field

  • Nuclear power plants: working in nuclear power plants, managing operations. Also, studying nuclear materials. Studies include methods to reduce material degradation to extend reactor life.
  • Reactor fuel/core design: ensuring the safety of nuclear fuel. Also, improving the economy of nuclear power generation. In other words, making the power generation process more efficient. As a loose analogy, think of car engines. You can improve the miles per gallon range by tweaking engine parts.
  • Nuclear submarines: designing smaller, lighter, more efficient, and safer reactors for submarines.
  • National labs: doing radiation detection work. In other words, modeling and simulating anything nuclear energy-related, to learn more about nuclear power.
  • Accident analysis: nuclear reactors have a lot of fear associated with them. So, doing accident analysis on reactors, using many different failure case scenarios. This will keep our cities safer and calm the minds of people.

Amazing work done in this field

  • Achieving self-sustaining nuclear reactions: this allowed nuclear power plants to safely power cities. Also, it enabled submarines to stay underwater for up to 4 months.
  • First nuclear-powered submarine built-in 1955: nuclear subs traveling deep in oceans for months. We basically power a mini-city underwater for months at a time without resurfacing. Amazing!
  • Global nuclear reactors: today, 430 nuclear reactors provide 13% of the world’s electricity. I’m amazed, considering only one-hundred years ago, renewable energy didn’t even exist at scale.
  • America’s clean energy: nuclear power generates 55% of America’s clean energy. A large number we don’t hear about in the news, given how the media negatively views nuclear power.

Interesting future work in this field

  • Fusion reactors: designing and developing a viable nuclear fusion reactor. This would revolutionize energy.

What does fusion power give us? An energy density greater than any other source of power, with near-zero pollution. Also, it gives us the ability to switch the power off and on, without the risk of a meltdown.

  • Modular reactors: greater usage of small modular reactors to help with power generation. These reactors would better help provide power to remote isolated areas. They have easy installation, with less required construction on-site and increased containment efficiency.
  • Safety factor: increasing the safety of existing nuclear reactors. Creating safety mechanics without human supervision required. As we learned, humans no matter how smart will make mistakes over time.
  • Transportation: using nuclear reactors in other vehicles outside of submarines and aircraft carriers. Possibly one day harnessing the power for our space vehicles to travel deep into space.
  • Waste treatment: improve existing waste treatment protocols. This will reduce the toxicity of radioactive waste. Also, to find new and safe use cases for radioactive waste.

#17 Petroleum Engineering

petroleum engineering oil rig in ocean

Petroleum engineering no longer stands tall as that hot profession. At one time black gold, fossil fuel, made the world go around.

But today, a new competitor enters the arena, renewable energy. Fossil fuels cannot beat renewable energy in a fight. We have already selected the winner.

Also, we no longer tolerate pollution as a society. Another hit against fossil fuels.

Today I see the entire landscape of energy changing. You’ll see and hear about climate change everywhere you go.

As a result, the petroleum industry no longer stands tall and confident. Petroleum engineers can see the writing on the wall.

From all the types of engineering, this field I foresee the most difficulties for.

That said, you can still make a great career in petroleum engineering. Even with the industry shrinking. I’ll bet it’ll be a rocky path though.

With that out of the way, petroleum engineers deal with hydrocarbon production. Think of crude oil or natural gas.

In other words, petroleum engineers help to find and extract oil and gas from below the Earth’s surface.

Challenge with Petroleum Engineering

These days, we’ve already extracted a lot of the oil from the easily accessible areas on Earth. So, the expertise of petroleum engineers becomes even more important.

These engineers now venture deeper and farther into all corners of the globe. All in the search for fossil fuels. So, this work now requires greater innovation combined with exploration.

Think of stationed oil rigs in the ocean. They drill deep into the ocean floor just to extract fossil fuels.

Imagine your favorite video game played on the ‘hard’ difficulty. I compare that to the challenge these engineers will now face. Moving into the future, it’ll only become more difficult to extract fossil fuels.

Knowing this, these difficulties have turned into another win for renewable energy.

Think about installing a wind turbine in a windy area versus drilling miles down into the ocean? I would choose the wind turbine option every time. Easier to install and much more cost-friendly.

The Process for Exploring and Drilling

Petroleum engineers first evaluate potential oil and gas reservoirs. For example, would a given reservoir make for good drilling?

The deeper we drill into the ground, the cost of drilling will naturally increase. So, the economics of future drill sites becomes a hot topic of discussion.

Next, after approval of a drill site, petroleum engineers would oversee the drill work. Throughout this process, they need to figure out how to best recover the oil in the ground.

Upon completion of drilling, they’d plan the collection of any spilled oil. With stricter laws, cleanup costs have increased post drilling, further hurting the profession. A much wider lens now watches over pollution.

Drilling today requires extra care and detailed planning. The deeper I look into the future, the greater the difficulties I foresee. Even with improved tech, I foresee trouble for this profession.

That said, I’m thankful for the work of petroleum engineers in the past and present. We live in a transitional period today with renewable energy leading the race.

But, without the hard work of petroleum engineers, we wouldn’t even have this discussion. Frankly, we wouldn’t have any of today’s comforts.

Petroleum engineers sparked our technological age. They indirectly ignited the 100% renewable energy dreams we now have today.

All types of engineering stand tall on the shoulders of petroleum engineers. They gave way to today’s great advancements.

#18 Software Engineering

software engineering writing computer code

The media always talks about software giants taking over the world. Think of life without Facebook, Apple, Google, Amazon, and Netflix.

I find it very difficult to think of the world without them. Also, I’ve only listed a few of the software giants who run the world today.

Software companies today even influence who we vote into political office. To that end, every industry and all types of engineering today depend on software to survive.

That said, software engineers write software. A set of instructions that tell a computer what to do and how to perform a task. Typically, the software automates a group of steps we already do as humans.

To rephrase it, the software automates certain steps in a process. This makes given processes much more efficient.

Moving along, software goes beyond applications you directly use. Think of these following apps you use on your phone:

  • Google maps
  • Facebook
  • Instagram
  • Twitter
  • Whatsapp
  • Amazon

So, we use software for things you don’t see as well.

For example, a lot of software runs in the background of your computer. This software makes your computer simply work.

Think about your computer’s operating system. You may have Microsoft Windows Operating System installed. A very complex software. Windows 10 includes roughly 50 million lines of code. Insane!

Scope of Software in All Types of Engineering

The many types of engineering directly benefit from advancements made in software. I’m familiar with all the types of engineering and I know they all highly depend on software these days.

Imagine the ability to do calculations instantly, with countless variables considered. This makes your work effortless. I use engineering software for this reason almost every week.

Now, think of our power grid. Today, software controls and runs our power grid.

In fact, software allows our power grid to grow in complexity. All while remaining manageable for us humans.

But, this also makes the power grid highly vulnerable to an outside attack. Especially since the software ties entire regions together. The scope goes well beyond any one human or entity.

Any attack on our power grid could instantly shut down our entire economy. Life today as we know it depends on power and in turn depends on software.

That said, all of society and all types of engineering need software engineers. I view software as the ladder that’ll lead us, humans, to our next level of evolution.

Software Engineering Info Nuggets

Cool types of jobs in this field

  • Artificial intelligence (AI) / machine learning: building the future with software that learns like a human. Except much smarter. The AI can then replace humans in almost every type of work, making work processes more efficient.
  • Blockchain developer: developing blockchain systems and protocols. As well as developing apps using blockchain tech.
  • Software security: building better security to protect computer systems. As software takes over more industries, industries will become more vulnerable to attacks. These attacks become more common too when systems stay connected to the Internet.

In software security, you build a wall, but hackers can always build a taller ladder. A constant cat and mouse game.

Amazing work done in this field

  • Software affecting and bettering every industry: the modernization of every industry through software. Every industry uses software to deliver better products and services. In return, to increase profits.
  • Powering the computers of today: software made computers accessible to everyone. Think of Microsoft’s Windows Operating System. It allowed us to do so much from the comfort of our own home.

  • Self-driving cars: the beginning chapter of cars driving autonomously on roads and highways.

Interesting future work in this field

  • Advancing artificial intelligence (AI): undoubtedly, AI drip-feeding into everything humans do. As a result, AI transforming life as we know it today.

Speaking with retired power engineers, I learned how they did calculations and design drawings all by hand not so long ago. Now today, I could never imagine doing a design drawing by hand. I rely too heavily on my drafting software, AutoCAD. Hard to imagine how far we’ve advanced in so little time.

  • Advancing augmented reality (AR): the real transition from Sci-Fi to reality. With everyone today holding a phone, mobile will soon adopt AR. Then we can experience the real world enhanced by a computer through the palm of our hands. Imagine assembling an IKEA desk with the help of AR.
  • Advancing virtual reality: imagine plunging into a new reality instantly. For instance, immersing yourself into a new world for both work and play. Also, bringing along a colleague or friend from the other side of the globe with you. How cool!
  • Internet of Things (IoT): will become more and more a part of our everyday lives. Imagine a fridge that orders food before it runs out, doors that recognize you and unlock, and so much more.
  • Blockchain: will only become more popular and advanced even if you don’t believe much in crypto. Already today, a lot of investment money floods into this area of work.
  • Global software adoption: further spreading software tools and applications around the globe. This will help better the lives of people from all walks of life.
  • Visual programming: making software development more visual. Thus, making computer programming more accessible to a wider audience. In other words, making computer programming simple and easy to do.

Wrap up Over the 18 Types of Engineering

We finally reached the end of the road. I covered so much with the 18 types of engineering but I left out even more.

At this point, I hope you learned a thing or two about engineering. To rephrase it, you at least agree that for not for engineering, we’d go back living in the stone ages.

Slight exaggeration, but you get my point.

In brief, engineering shaped the entire world we live in today. In particular, from how we entertain each other, how we travel, what we eat, and how we communicate.

I hope you now have a pulse on all these amazing fields. Also, a better beginning understanding of how to be an engineer.

All in all, in the world we live in today, all these types of engineering I’ve covered work together as one. Whether directly, or indirectly, all these types of engineering cannot thrive alone.

For example, you can’t design and build a building without many types of engineering working together. Think of football, where a quarterback alone can’t win you the game.

So, all types of engineering play an important role in shaping today’s world. On that note, whether you want to start a career in engineering, or you simply have a deep interest, you have many options.

People of all backgrounds become engineers. The task of becoming an engineer may seem daunting at first.

But, you can do it. I even overcame the imposter syndrome in engineering. Now today, I never second guess myself in my work.

In summary, each engineering field has countless layers of complexity. They each require more than a lifetime to master. One reason why so many subspecialties exist in each of these types of engineering.

What the Future Holds

Overall, moving into the future will make all these types of engineering more complex. To that end, advancements in one field will directly benefit many other fields.

As a result, you’ll see advancements made in all the engineering fields at incredible speeds. I view it as a loop, where new technology feeds off of existing technology and repeats.

In short, we live in an amazing time where the many types of engineering have created our wildest dreams. Without a doubt, dreams humans couldn’t have imagined only several centuries ago.

Thus, I’m thankful to have a part in this movement. To put it another way, we all live in a big anthill with everyone contributing to the next step in human evolution.

Which types of engineering most interest you? Which of the types of engineering do you think will make the greatest advancements 100 years from now? Do you envision any new fields of engineering in the future?
