The Ultimate Guide to the 18 Types of Engineering

This article covers 18 popular types of engineering. I’m going to go over each field, and give you a lot of info nuggets too.

As I go through the 18 types of engineering, you can find answers to the following questions:

  • Which field of engineering is for me?

Also, you’ll understand why I think engineering skills are powerful in the real world.

Subfields for each of the types of engineering

By and large, each field of engineering includes many subfields.

Take a step back and look around. Each technology you see has a specialty of its own.

So even if I tried, I couldn’t list all the types of engineering.

Instead, I’m focusing on what I think are the 18 main types of engineering. Then I’ll drill into subfields I find important.

Limitations with describing the 18 types of engineering

Without a doubt, overlaps exist with these 18 types of engineering.

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

Frankly, who cares! On the whole, I want you to learn about the amazing world of engineering.

And if you don’t agree with my breakdown, I won’t take any offense.

To that end, use the below table of contents to jump to any field you like. 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 Star Trek TV series. This quote perfectly fits the aerospace industry.

In aerospace engineering, you literally go where no one has gone before.

To point out, “aerospace” is our pursuit to fly in Earth’s atmosphere and beyond. Think of planes, jets, helicopters, drones, and even rockets and spaceships.

Not to mention, designing satellites and missiles. So, aerospace engineers fight the force of gravity with their designs.

This is how trips from America to Europe now take less than 10 hours. Whereas a century ago, it took 6 weeks of sailing in turbulent oceans.

What’s more, aerospace engineers can call themselves “rocket scientists!”

Aerospace engineering subfields

Aeronautical: design and develop aircraft. Think of airplanes and jets, gliders, and helicopters. These are crafts designed to fly inside of Earth’s atmosphere.

#2 Agricultural Engineering

agricultural engineering tractor working the farm

With the number of mouths to feed today, we can’t just plant a seed and hope for the best.

We need smart machines to run farms. Otherwise, we can’t produce crops at scale to feed growing populations.

To illustrate, think of the high-tech tractors. They comb through cornfields methodically like robot insects.

We need to bring all farms into this new age of tech.

To that end, agricultural engineers work to make farms operate more efficiently. They design and setup farming machines, layouts, and management styles.

Climate change and farming

With the changing climate, agricultural engineers need to recreate ideal crop environments. Otherwise, growing populations will starve, as crop yields drop.

So, on top of machine design, agricultural engineers modify and augment environments.

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

I believe climate change will greatly advance agricultural engineering. Because we need to protect farmers, as they’re the backbone of economies

Cool jobs

  • Machine design: design autonomous farming machines.
  • Farm layouts: design layouts to protect crops from weather elements and insects.
  • Application engineer: update existing farms with the latest practices and tech.

#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. Who does?!

To that end, audio engineers handle the technical side of audio. For example, recording, mixing, and reproducing sound. They’re modern-day high-tech Mozart figures.

Now, think about a concert you went to. The sound was crisp. Even over tens of thousands of loudly cheering fans.

My point is, there’s much more to sound production than turning a nob to increase volume. Or simply hitting a “record” button.

#4 Bioengineering

bioengineering designing prosthetic implants for human body

“Bio” in Greek means life. Thus, in bioengineering, you design and build around life.

I’ve always loved how movies show the merging of man and machine. Because it’s the natural evolutionary step for humans.

Now, bioengineers, also called biomedical engineers, may not build deadly cool looking terminators. But their work is transforming human life.

Think of prosthetics, medical devices, drug delivery, and so on. We now modify genes, heal faster, and allow double-leg amputees to walk.

Even more, next time you visit your doctor’s office, look around. Look at the equipment and study the medical protocols.

When I need medical treatment, I want the best Doctor. But I also want the best facility. You need both to get the best treatment these days.

In fact, you’ll get poor treatment without modern tech. What’s more, I believe engineering has attributed more to improved human health than doctors.

Bioengineering scope goes beyond the medical field

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

For example, think of the many foods you buy and eat. You may have come across a “GMO” label at the grocery store.

GMO, Genetically Modified Organism, are foods we modify. In other words, these are foods we can’t create through regular breeding, and they don’t exist in nature.

Rather, bioengineers create these foods using enzymes and living cells.

#5 Chemical Engineering

chemical engineering discovering new materials

Undoubtedly, synthetic materials rule the world. Just look at your car, TV, iPhone, basketball, and so on.

These product materials weren’t found underground. They’re lab-made.

More than likely, a chemical engineer spent countless months perfecting the material. Thus, engineering chemicals and chemical processes to create raw materials for different products.

Additionally, they improve existing materials. We can always make materials stronger, lighter, cheaper, and safer for the environment.

Every frustration you’ve ever had with a material becomes a future project. For example:

  • Weak tool handles that easily break
  • Phone screens that easily crack
  • Kitchen gloves that can’t withstand much heat

#6 Civil Engineering

civil engineering constructing building and placing structural foundations

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

Civil engineers designed our modern-day cities. Also, cities from centuries ago.

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

Even more, without city infrastructure, the other types of engineering wouldn’t have existed. We need roofs over our heads, and roads to travel on before we can innovate.

Different Subfields of Civil Engineering

Unquestionably, computer engineering advances at rapid speeds.

Your phone has 100,000 times more processing power than the 1969 Apollo 11 computer. The computer used to travel to the moon.

To point out, this rapid advancement benefits all types of engineering. Both in hardware and software.

Hardware engineering: design and develop computer components. For example, processors, memory devices, network devices, and circuit boards.

#9 Environmental Engineering

You’d think the smarter we become as a species, the more we’d protect our planet. But human greed makes us do crazy things.

For example, I hear so much negative talk towards environmentalists. I hear how they delay engineering projects and make projects more complex.

Yes, it’s true. BUT, engineers need boundaries.

Otherwise, even the noblest engineering project over time can destroy a region. This is then where environmental engineers come into play.

In brief, they help clean up the mess. They use engineering principles to create solutions to environmental problems. For example, managing waste disposal, public health, recycling, and pollution control.

Cool jobs

  • Air quality control: maintain air quality as populations grow.
  • Water/wastewater: design dams, diversion structures, and sewer lines.

#10 Geotechnical Engineering

Geotechnical engineers analyze the engineering implications of soils and rocks. They then pass their findings to different types of engineers for their designs.

For example, structural engineers need to know the soil type before building skyscrapers.

I also get soil information from geotechnical engineers. For the most part, I need this information for ground grids I design.

To point out, different soils have different resistivities. Specifically, the soil type affects how electricity travels through the ground. An unsafe ground grid can kill people.

In short, the work of geotechnical engineers dictates the direction of many designs.

#11 Industrial Engineering

Generally, the more complex systems become, the more optimization they require.

Decades ago, a few people in a factory would screw on tires and glue on components and then call it a day. For the most part, very simple and straightforward work.

Today, factories include hundreds of workers and machines. In short, this requires huge coordination efforts.

To illustrate, think of a car manufacturing plant. Robots and humans seamlessly work together, resembling an in-sync symphony.

I find the assembly line just as amazing as the finished car.

Industrial engineers design these efficient processes. For example, they add and remove process steps to find how best to get from point A to B.

  • AI and robots: integrate AI and robots into all factories.

#12 Materials Engineering

Material engineers choose best-fit materials for products.

Given that, choose the wrong material and a plane will fall out of the sky.

With this in mind, don’t confuse a materials engineer with a chemical engineer. Yes, both types of engineers use a lot of chemistry.

But, a materials engineer focuses on the materials themselves. In other words, they work to understand why and how materials perform the way they do. Thereafter, they figure out which material would work best for a given application.

For example, material engineers work to find the best material for helicopter blades.  They’d need to find an affordable lightweight yet strong and flexible material to use.

Improving existing products

Imagine we make a cheaper, lighter weight, and stronger material than aluminum. Material engineers would then recommend this material over aluminum for planes.

Planes would then save on fuel costs due to the reduced weight, and flights would become safer.

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

Cool jobs

  • Nanomaterials: use of nanomaterials to improve material specs. For example, making materials stronger, and lighter weight.
  • Environment protection: greater use of environmentally friendly materials in products.

#13 Mechanical Engineering

No tech without mech. Undeniably, the ‘mother’ branch of engineering.

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

They have a point though. Most tech wouldn’t work without mechanical engineers. To rephrase it, most everything has moving parts.

Plus, who’d disagree with Leonardo da Vinci who once said,

“The power of water has changed more in this world than emperors or kings”.

For example, hydraulic turbines convert energy from flowing water to electric power.

Cool jobs

  • Product design: design any products with moving parts.
  • Nanotech: alter materials at the smallest levels. Use this technology in the food, energy, water, machine, and environment industries.

#14 Ocean / Marine Engineering

ocean engineering - building devices and equipment for seas and coasts

Surprisingly, the oceans cover 71% of Earth and make up 97% of the water found on Earth.

Even more fascinating, 80% of oceans have gone unexplored. Yet, we still seek to travel to other planets.

Ironic, considering we haven’t explored a large part of Earth. This just shows how big and mysterious Earth still is.

To that end, ocean engineers work around oceans or any body of water. They combine their knowledge of water with other engineering fields. For example, electrical, civil, mechanical, acoustical, and chemical fields.

The difference is, the playing ground changes from dirt to sand and water. But the used science and math remain the same.

For example, ocean engineers design and build equipment for offshore and coastal areas. This equipment can then be used for coastal city construction or even oil rig work.

Also, they help scientists better explore and learn about our oceans. Without their work, we wouldn’t have been able to visit the Titanic 2.4 miles down in the Atlantic Ocean.

#15 Mining Engineering

Earth houses many amazing metals and minerals.

To that end, mining engineers work to remove these metals and minerals from inside Earth. They also typically specialize in the mining of only one type of metal or mineral.

This is because each material has unique challenges. Thus, only mastery allows for safe and profitable mining.

In this pursuit, mining engineers do the following types of work:

  • Design and test machines
  • Come up with mining techniques
  • Brainstorm processes to efficiently remove materials
  • Devise methods to store excavated soil

#16 Nuclear Engineering

nuclear engineering power plant using nuclear fission

Unquestionably, nuclear power plants have received a bad rap over the years. Some of it I get. But, we can’t deny their positive impact.

For one thing, nuclear energy powers a lot of the world today. Equally important, without polluting by burning fossil fuels.

Even more, the tech is now much safer even with human error factored in.

A lot of this is due to the great work of nuclear engineers.

But, I don’t believe nuclear engineers will ever reach a safe enough design. I can’t see the fear surrounding nuclear energy subsiding anytime soon.

Regardless, nuclear engineers will continue working on nuclear energy and radiation. More specifically, on sub-atomic processes relating to fission and fusion.

  • Nuclear fission produces atomic bombs and is used in nuclear power reactors
  • Nuclear fusion powers the Sun

Pursuing fusion energy

In short, the development of fusion power is the holy grail of power generation.

Fusion power is the best limitless clean energy we could ever harness. Without a doubt, it would forever change human life.

Even more, fusion power may become our ticket to traveling into deep space.

Cool jobs

Petroleum engineering no longer stands tall as that hot profession. To put it differently, at one time, black gold, fossil fuel, made the world go around.

At the present time, it has taken a back seat to renewable energy. Without a doubt, we’re less and less tolerating pollution.

Climate change is now on everyone’s radar. But I can’t imagine fossil fuel demand ever completely going away.

Because fossil fuel just has such a high net energy yield. This makes it ideal for many applications still.

At any rate, petroleum engineers work with hydrocarbon production. For example, working with crude oil or natural gas.

Specifically, finding and safely extracting oil and gas from below the Earth’s surface.

Cools jobs

  • Reservoir engineer: evaluate reservoirs for content and extraction methods.
  • Production engineer: determine how best to drill into reservoirs effectively and safely. Then seal the reservoirs after drilling to avoid leakage.

Amazing accomplishments

  • Pollution control: drill and extract resources successfully with limited pollution.
  • Locating resources underground: pinpoint oil and gas reservoir locations around the globe.
  • Ocean drilling: drill over a mile below the ocean surface.

Future pursuits

  • Deep drilling: drill deeper into Earth for oil and gas.
  • Clean drilling: reduce drill costs and pollution.
  • New industry: transfer the tech and processes from petroleum engineering to new industries.

#18 Software Engineering

Undeniably, software giants rule the world today. Think of life without Facebook, Apple, Google, Amazon, and Netflix.

Yes, life would be very different.

Even more, every industry and all types of engineering depend on software today.

To that end, software engineers write software. A set of instructions telling computers what to do and how to perform tasks.

Generally, software automates groups of steps we already do as humans. Thus, it makes processes more efficient.

Also, software goes beyond applications you directly use. For example, a lot of software runs in the background of your computer, making it simply work.

To illustrate, think of Microsoft Windows Operating System. Windows 10 includes roughly 50 million lines of code.

Cool jobs

  • Artificial intelligence (AI): build the future with software that learns better than humans.
  • Blockchain developer: develop blockchain systems and protocols.
  • Software security: improve software security for industries.

Amazing accomplishments

  • Software affecting and bettering every industry: the modernization of every industry through software.
  • Microsoft Windows: software made computers accessible to everyone.
  • AlphaGo: a computer program that plays the complex board game ‘Go’. The program defeated a pro-human Go player in 2015.
  • Self-driving cars: semi-autonomous cars on roads.

Future pursuits

  • Advancing artificial intelligence (AI): drip-feed AI into all industries.
  • Advancing augmented reality (AR): simplify work through AR. Imagine assembling an IKEA desk with the help of AR.
  • Advancing virtual reality: build lifelike digital environments.
  • Internet of Things (IoT): imagine refrigerators order food before they run out, and doors recognize you and unlock.
  • Blockchain: greater widespread usage, and adoption by governments.
  • Global software adoption: software applications made accessible to all people across the globe.
  • Visual programming: software development made more visual. This will make computer programming accessible to a wider audience.
