Computer Science vs Engineering

This comparison gets complicated because "engineering" is not one major. It is a family of disciplines: mechanical, electrical, civil, chemical, aerospace, biomedical, and more. Each has different coursework, career paths, and salary ranges. When students say "CS versus engineering," they usually mean CS versus one specific engineering discipline, often electrical or mechanical engineering.

The core difference: computer science is primarily about abstract problem-solving through software. Engineering is about solving physical-world problems through design, analysis, and manufacturing. Both use math extensively. Both are demanding. But a CS grad's work product is code, while an engineer's work product might be a bridge, a circuit board, a chemical process, or a jet engine.

At a Glance

Coursework Differences

Computer science coursework:

• Data structures and algorithms (the core of CS)
• Operating systems
• Computer architecture
• Database systems
• Software engineering
• Discrete mathematics and formal logic
• Programming languages and compilers
• Artificial intelligence and machine learning (upper-level)
• Networks and distributed systems

CS is primarily cerebral and abstract. You work with code, logic, and mathematical proofs. The lab component involves programming, not physical equipment. Upper-division courses give you increasing freedom to specialize in areas like AI, security, systems, or theory.

Engineering coursework (using mechanical engineering as an example):

• Statics and dynamics
• Thermodynamics
• Fluid mechanics
• Materials science and engineering
• Machine design
• Manufacturing processes
• Heat transfer
• Control systems
• Senior capstone design project

Engineering is more physics-intensive and involves hands-on work with physical systems. You design, prototype, test, and iterate on physical objects. Lab work involves measurement equipment, testing apparatus, and often machine shop work. The capstone project typically involves building something real.

Career Path Differences

Computer science careers:

• Software engineer/developer ($136,620 median for all experience levels)
• Data engineer/ML engineer ($90,000-$180,000)
• DevOps/site reliability engineer ($90,000-$170,000)
• Cybersecurity analyst ($120,360 median)
• Technical product manager ($100,000-$160,000)
• Full-stack developer ($80,000-$150,000)

Engineering careers (varies by discipline):

• Mechanical engineer ($99,510 median)
• Electrical engineer ($108,170 median)
• Civil engineer ($95,890 median)
• Aerospace engineer ($130,720 median)
• Chemical engineer ($112,100 median)
• Biomedical engineer ($101,020 median)

CS careers are concentrated in tech companies, startups, and the technology departments of every industry. Engineering careers are more distributed across manufacturing, construction, energy, aerospace, automotive, and defense. The work environments are different: CS professionals typically work at a desk with a computer. Engineers may split time between offices, manufacturing floors, laboratories, and field sites.

Salary Comparison

CS salaries are generally higher, particularly in the first decade of a career. Software developers earned a median of $136,620 in May 2024, compared to the all-engineering median of $91,010¹². However, this comparison is somewhat unfair because the CS median includes experienced senior engineers at tech companies.

At the entry level, the gap is smaller. CS starting salaries range from $65,000 to $90,000 at most companies (with top tech companies paying $100,000+). Engineering starting salaries range from $60,000 to $80,000 for most disciplines, with petroleum and computer hardware engineering starting higher.

The CS salary ceiling is higher because of the tech industry's compensation structure, which includes stock grants and bonuses that can double total compensation at senior levels. Engineering salaries grow more steadily, with less extreme upside but also less volatility.

Which Is Right for You?

Choose computer science if:

• You enjoy abstract problem-solving, logic, and building software systems
• You want to work primarily at a computer
• You are comfortable with a rapidly changing field where yesterday's skills become outdated
• You want access to the highest-paying starting salaries and the tech industry compensation model
• You like the flexibility of working remotely (many CS roles are remote-friendly)

Choose engineering if:

• You want to design and build physical things
• You enjoy physics, hands-on work, and seeing tangible results
• You want a career with professional licensure options (PE license)
• You prefer more stable, less volatile career paths
• You are interested in aerospace, energy, infrastructure, manufacturing, or automotive industries

Choose computer engineering if:

• You want to work at the intersection of hardware and software
• Embedded systems, chip design, or IoT (Internet of Things) interest you
• You want engineering rigor with programming skills

FAQ

Is computer science considered engineering?

Academically, it depends on the school. Some universities house CS in the engineering college; others place it in arts and sciences or its own school. Professionally, software development is not regulated as engineering in most jurisdictions (you do not need a PE license to write code). Computer engineering, however, is an accredited engineering discipline with ABET accreditation.

Is engineering harder than computer science?

Both are demanding but in different ways. Engineering requires more physics and hands-on design work. CS requires more abstract mathematical reasoning and programming. Attrition rates are high in both fields. The "harder" major depends on your individual strengths: if physics and spatial reasoning come naturally, engineering may feel more manageable. If logic and abstract thinking are strengths, CS may feel easier.

Can I switch from engineering to computer science or vice versa?

Switching is easiest in the first two years when coursework overlaps (calculus, physics). After sophomore year, each major's specialized courses diverge significantly. Switching from engineering to CS is common because many engineering students discover they prefer programming. Switching from CS to engineering is less common but possible if you catch up on physics and discipline-specific courses.

Do engineers make more than software developers?

Generally no. Software developers earn higher median salaries than most engineering disciplines. However, some engineering specializations (petroleum, computer hardware) match or exceed software developer salaries. At the very top, senior software engineers at major tech companies earn more than most engineers through stock compensation, but the comparison is between a small elite in each field.

Can engineers learn to code?

Yes, and many do. Most engineering programs include at least introductory programming courses (often MATLAB, Python, or C). Engineers who develop strong programming skills can transition into software roles, data analysis, or computational engineering positions. The math foundation from engineering transfers well to CS-adjacent careers.

Which is better for entrepreneurship?

CS provides more direct tools for building tech startups (you can build a product with a laptop). Engineering provides skills for hardware startups, manufacturing businesses, and technical consulting firms. Both are strong foundations for entrepreneurship, but CS has a lower barrier to entry for starting a company because software products require less capital than physical products.
