What is Computer Engineering?

The term computer engineering puts together two words that a lot of people associate with college. For years, and now maybe more than ever, people who know a lot about either of these words and make them their professional business are in high demand. 

Still, the computer engineering curriculum is a mysterious topic. A subject you might not think of as a realistic possibility. A made-up job for movie characters and people you never meet, because they’re too busy working alone in front of glowing screens.

Let’s start at the beginning, bring out some facts and work on a computer engineering degree definition. You should hopefully see why it could be a very real option for you.

What do computer engineers do?

Computer engineering is the combination of computer science and electrical engineering to develop new technological innovations. Essentially, what sets it apart from the other engineering disciplines like mechanical engineering and electrical engineering is that computer engineers build, design and maintain different parts of the triangle that is a working computer: hardware, software and computer networks. Unsure as to the answers to “What is mechanical engineering?” or even “What do electrical engineers do?” We’ve got your answers!

So, what does a computer engineer do, exactly?

Hardware engineering

Focusing on computer hardware engineering means that you get to have a lot of hands-on experience and learn the fundamentals of building machines and using automation, as well. The computer hardware engineer builds CPU towers, laptops, monitors, tablets, smartphones, servers, and any other machines that have a computer inside.

Software engineering

Computer software engineers create the programs and intelligent systems that instruct hardware what to do: operating system, mobile apps, PC and console video games, computer-aided design software—anything with an icon you tap, click or double-click to start up.

Network engineering

Network engineers set up and maintain the huge, complicated connections between computers that allow them to talk to one another, whether in the same building or across the world through the Internet. Enjoy your lightning fast Wi-Fi? Thank a computer network architect or engineer.

Because of our obvious reliance on computers, professional computer engineers are all over the place. You can find work in any number of industries to apply such engineering disciplines, while strengthening your skills. 

Career Opportunities

With your computer engineering degree, you can work for:

Banks and financial institutions

You can work for banks and in finance creating applications or building a complex computer system.

Chemical manufacturing industry

You could find work with a chemical manufacturer, designing programs to test and analyze new products. 

Transportation industry

The transportation industry hires computer engineering majors to help automate trains, design fuel systems and navigational software for jets, or even big, futuristic projects like self-driving cars.

Manufacturing industry

Manufacturing is becoming more and more the work of programmed machines, so you could find work designing and building the very robots that put cars, household appliances, and even computers themselves together.


If nothing else, a trained computer software engineer can get great work as a consultant for companies with big ideas who don’t know how to use computing to make them happen—things like virtual reality technology and artificial intelligence. And there is always the biggest of computer engineering jobs—working for the government or defense contractors to help design the machines and digital computer systems used to protect people.

Again, everyone needs computers to get their jobs done, but many fewer people than that know how to get computers to do what they want. A degree in computer engineering will set you up for career opportunities just about anywhere, where you will be highly valued by whomever you work for.

Some of the job positions for computer engineers:

  • Computer scientists
  • Network architect
  • AI designer or developer
  • Software developer
  • Technical support representative
  • Database developer
  • Data scientists
  • Data analyst
  • System manager
  • Security analyst
  • Web designer
  • Information technologist
  • Marketing coordinator
  • Technical Writer
  • Teacher

What is the difference between computer engineering and computer science?

Both complex and important subjects, computer engineering and computer science go hand-in-hand. You can’t fully understand computer engineering without computer science, but you must understand that they are very different in practice before you choose one as your career path.

The easiest way to explain the contrast is this: computer science is all about theory while computer engineering is about execution. 

Computer science

Computer science is about coming up with possible solutions for real issues and complex engineering problems. You have to literally use your skills to think like a computer, meaning a lot of math, data analysis and reading and writing code using a specific computer language. Computer scientists design a lot of things without actually building them, like web structures and user interfaces, and teach computers to be better and more efficient, directing them how by writing code.

Computer engineering

Computer engineering majors work more in the physical, doing other things with your hands along with typing. While computer programming is vital knowledge, you also have to be skilled in physics and electronics. You need to know how circuits fit together, how processors work, the ins and outs of drives, and anything else that might be going on under the hood of a computerized device. 

What are some computer engineering courses?

Another big distinction between the two areas is the courses you’ll take if you major in one or the other. Typical computer science classes cover:

  • Design and Analysis of Algorithms 
  • Operating Systems 
  • Software Engineering 
  • Data Analysis 

Whereas a basic computer engineering curriculum is more like:

  • Mechanics 
  • Electricity and Magnetism 
  • Calculus 
  • General Physics 
  • Electric Circuits 
  • Waves, Optics, Thermodynamics 
  • Digital Logic 
  • Machine Design 

Is Computer Engineering a good career?

As we discussed before, there are certainly plenty of jobs available for computer engineering graduates, including entry level positions. Areas like robotics, mobile device design, telecommunication and the aerospace industry area always in need of good computer engineers.


The U.S. Bureau of Labor Statistics projects that for a computer hardware engineer in particular, job opportunities should increase 5%--a rise of 3,700 positions—by 2031.

Beyond that, salaries for computer engineers tend to be quite strong. 

According to Payscale, a bachelor of science degree in computer engineering can get you a position with starting salaries in the $92K per year range up to higher-level salaries close to $120K a year with the average yearly salary sitting at $86,000. A master’s degree, whether on campus or an online masters’, pushes the average into six digits at $103K per year, with the lower end of the scale rising by a lot.

Job security

Job security and take-home pay aren’t everything, though. You may be wondering about work-life balance for computer engineering professionals.

Tech jobs, the kind computer engineers find themselves in often, are known for expecting a ton of hours on the job and not a lot of allowing for family time or vacation. The proof is in the fact that a lot of tech companies have made a point to mention how much they value work-life balance on their job listings.

This goes both ways, though: computer engineering technology continues to grow with no slowing-down in sight. Companies know they need massive, well-trained groups of employees to keep up in a tough market, and they’re willing to do what it takes to keep their workforce happy.

In short, if you have a passion for the kind of work computer engineering takes, go for it—but keep in mind that you may need to devote yourself to more than a 9 to 5 life. Be sure you love this work and that it makes you happy, because it’s not something you want to be stuck in without the joy of going to the office. 

When you apply for jobs, make sure your questions for future bosses include asking about work-life balance. The better their answer and the easier they come up with it, the more you know they’re aware it’s important.

What is a computer engineering major?

We mentioned above some of the classes you should expect to take in your computer engineering major. Once you have those basic courses, you will move into more specialized areas as you choose what parts of computer engineering you like best. You’ll study things you may never thought you’d get a chance to take a course in, like bioinformatics, Linux computer programming, game design and development, computer architecture, software development, and data mining. 

A capstone project will more than likely be at the end of your degree program. While that means a lot of research, writing and presenting, it also means you’ll get a chance to build a computing project of your own, which could even launch the next big idea in computing.

What is a good computer engineering program?

Here are a few things to look for in a strong computer engineering program:

  • Focus on automation and robotics
  • A lot of hands-on learning about how to design a digital computer system and analyze a high-end, embedded system
  • Emphasis on teamwork and problem-solving skills as well as computer engineering as life-long learning
  • Updated computer software and hardware and software in classrooms and labs
  • Opportunities to get internships at labs and tech companies
  • The chance to do research projects and go to competitions against other schools
