What is computer science vs. software engineering?

Both computer science and software engineering draw on similar technical and workplace skills. You will see an overlap between the two when it comes to the need for proficiency in software development, database management, and a variety of programming languages. Since both careers are often collaborative, teamwork and communication are also key skills for these fields.

The differences in skill sets point to the different approaches and end goals of each profession. Because software engineers handle the actual building and design of software products and computer systems, software engineers must be able to: 

• Create scalable domain-specific pipelines and languages

• Use the tools needed to develop software

• Test and debug software 

• Understand and work with programming frameworks 

Whereas those who work in computer science must be able to:

• Analyze and monitor new or existing software systems 

• Create software programs that are compatible with hardware systems 

• Test software programs 

• Write computer programs

Analyzing job outlook for each field

Computer science and software engineering fields are growing as technological advances continue to speed up and the demand for new software increases. 

The US Bureau of Labor Statistics (BLS) predicts that computer science employment will grow 20 percent between 2024 and 2034, a rapid growth rate compared to other fields [1].

Careers in computer science are continually evolving as professionals in this field discover new ways to use technology, creating more jobs as opportunities for technological development arise. With growth in areas like cybersecurity, organizations may also seek employees in the computer science field (such as computer engineers or computer programmers) to create new processes and collect and store data.

The BLS also predicts that the employment of software developers, quality assurance analysts, and testers (which includes software engineers) should grow 15 percent from 2024 to 2034, which is much faster than average [2]. This growth is also a result of innovation, but other factors include the constant demand for new software and mobile applications, increasing project complexity, and the need to rebuild aging systems using more modern technology. 

How much do computer scientists make?

The salary range for computer science jobs varies widely because of the variety of possible careers within the computer science field. For example, the median annual income for a computer programmer in the US is $98,670 [3], while the median annual income for a data scientist is $112,590 [4]. 

The median annual salary of a computer scientist working in the US is $140,910 [1]. Across the top related industries to work as a computer and information researcher, your salary may range from $85,290 annually to $237,990 per year, depending on your industry and job title [5]. 

How much do computer software engineers make?

Most software engineers in the US can expect to earn a median salary of $131,450 a year, according to the BLS [2]. For related positions, the salary range for software development jobs in top industries is anywhere between $129,890 per year and $149,990 per year, which also depends on the industry and job title [6]. 

How to increase your salary

If you’re currently working in computer science or software engineering, you’ll find some key ways to increase your salary by improving your skills. The good news is that both fields have quite a bit of room for gaining skills and abilities that are highly beneficial to employers. 

Innovation in these fields lends itself to salary increases, but only if you follow the emerging trends within your industry and equip yourself with the skills necessary to move forward. 

Learn a new technical skill

Train yourself to become an applicant for a higher-paying position by learning new in-demand technical skills in your industry. Computer science and software engineering fields offer various opportunities for upward mobility and promotion. 

In computer science, AI and deep learning skills are in high demand. Software engineers must be proficient in multiple programming languages and cloud-based technology.

Build your experience 

Whether you choose computer science or software engineering, you can accelerate your career growth through additional experience and network building. Consider attending industry conferences and events, taking online courses, or contributing to open-source projects on GitHub.

Pursue certifications or degrees

Earning certifications in a specific skill or area of expertise can lend itself to a boost in income and a bump in confidence as you gain knowledge. Some employers like to see individuals who focus on a particular specialty, and certifications can help you learn skills that make you a highly valuable employee. Seeking certifications can also show initiative and improve your standing regarding workplace skills like communication, teamwork, and leadership. 

Certifications to consider include:

• CompTIA A+ certification for computer science

• Microsoft Certified: Azure Fundamentals for software engineering

A bachelor’s degree is typically the first step in pursuing a career in either field. If you’d like to become a computer scientist, you’ll likely need a degree in computer science or a related subject. Some employers may require a master’s degree or even a PhD. For software engineering, you will often need a bachelor’s degree in computer and information technology, software engineering, or computer science. 

When choosing your program, think about what specialization would most benefit your career path in the long term. For example, if you have an interest in data analysis, you can seek a master’s in data science; if you would like to pursue game design, you can opt for a computer graphics program. 

Negotiate your current salary

If you seek to negotiate your salary as a computer scientist or a software engineer, keep in mind the importance of both your skills and experience.

In addition to certifications and degrees, building an impressive resume of real-world projects and quality references can be an effective bargaining chip for negotiating your current salary. As a software engineer, technical skills such as big data or continuous integration (CI) are in demand, and workplace skills like communication and problem-solving are also highly valuable. Strong programming skills are attractive for both roles. 

When it comes time to agree on an amount, make sure you’ve researched and understood the salary range for your job title and location.
