Software engineers turn people’s needs into software—and the work includes much more than writing code. They help define the problem, choose a design, build and test a solution, coordinate with teammates, and maintain and document the software after it is in use. The exact job varies by employer; U.S. labor statistics describe the closest occupation as “software developers.”
What does a software engineer do?
A software engineer works on the process of creating and improving software, from understanding what users need to helping keep a finished system useful. The title does not mean every engineer handles every stage, but software development commonly involves several kinds of work:
- Understand the problem: Clarify what users or an organization need the software to accomplish.
- Plan the solution: Decide how the software should work and how its parts should fit together.
- Build it: Write and revise code that implements the design.
- Test it: Check that the software behaves as intended and address problems that tests uncover.
- Maintain and improve it: Fix issues, make changes, and recommend upgrades as needs evolve.
- Document it: Record how the software works so teammates can use, maintain, or extend it.
The U.S. Bureau of Labor Statistics (BLS) describes development as usually collaborative. Developers may work with other developers and with quality assurance analysts or testers, among others. A software project is therefore not usually one person independently writing a complete program from scratch.

No. Coding is an important part of building software, but it sits within a larger cycle of understanding needs, making design decisions, coordinating work, testing, maintenance, and documentation. Some workdays may involve substantial programming; others may focus more on discussing requirements, reviewing a design, investigating a defect, or planning a change. The mix depends on the project and employer, so there is no single daily schedule that applies to every software engineer.

Software engineering is also a team practice. The ACM/IEEE-CS computing curriculum report treats sustained collaborative project experience as valuable preparation, while cautioning that one project with novice teammates is not a complete simulation of professional collaboration. A school project can help you learn how to work with others, but it cannot guarantee that you are fully prepared for every workplace situation.
How is a software developer different from a QA analyst or tester?
Job titles and boundaries vary across employers, but the BLS distinguishes the work broadly: software developers design and build applications or programs; quality assurance (QA) analysts and testers identify problems, design or run tests, and report defects. These roles can collaborate closely on the same product, and testing is part of the wider development process even when a separate QA role handles some testing tasks.
Rank #2
For U.S. labor-market statistics, “software developer” is the relevant BLS occupation to consult when exploring the broader software engineer title. Do not assume every employer uses “developer” and “engineer” identically or that one title covers exactly the same duties everywhere.
What preparation is typical?
The BLS says software developers typically need a bachelor’s degree in computer and information technology or a related field, such as engineering or mathematics. Some employers may prefer a master’s degree. These are typical patterns, not a universal rule for every employer or software role.
Students may gain development experience through an internship while in college. Collaborative projects can also provide useful exposure to designing, building, and improving software with other people. Treat both as ways to learn about the work—not as guarantees of job readiness or employment.

The BLS’s 2026 Occupational Outlook Handbook profile reports the following U.S. figures. The wage is for software developers; the employment projection and annual openings cover a combined group that also includes QA analysts and testers.
| Measure | Figure | What it means |
|---|---|---|
| Median annual wage for software developers, May 2025 | $135,980 | U.S. median: half of workers earned more and half earned less. It is not an entry-level salary or a prediction of what a particular person will earn. |
| Projected employment growth, 2025–2035 | 10% | U.S. projection for software developers, QA analysts, and testers combined—not developers alone. |
| Average annual openings, 2025–2035 | About 106,100 | U.S. average for software developers, QA analysts, and testers combined. Openings include positions created when workers leave or transfer occupations, not just newly created jobs. |
The BLS says its outlook reflects demand for software development involving artificial intelligence, the Internet of Things, robotics, automation, and security investment. That is the agency’s rationale for the outlook, not a guarantee of hiring or growth in any particular specialty.
Quick Recap
Best Value
How can you explore the field as a student?
- Try building something small. Choose a problem you can explain, then make a simple program or application that addresses it. Notice that deciding what to build is part of the work, not just writing the code.
- Test and revise your work. Check whether it does what you intended, identify what goes wrong, and make changes. This gives you a first look at the cycle of building and improving software.
- Work on a collaborative project. Share tasks and decisions with other students if you have the opportunity. Pay attention to how teammates communicate and coordinate—not only to the final result.
- Look for internships during college. The BLS identifies internships as one way students may gain development experience. Requirements and opportunities vary, so an internship is an option rather than a prerequisite that applies everywhere.
- Compare roles by their actual work. When you read about a job or program, check its duties, education expectations, location, and dates. Those details help distinguish a particular opportunity from broad occupational patterns.
