Ready to launch your career?

Software engineers are responsible for building—or engineering—any kind of software. There’s no limitation in terms of software type on what this can be. Software engineers can create desktop programs like GarageBand or PowerPoint, or mobile and web applications like Instagram or Gmail.

What is a software engineer, and what do they do? Learn more about a typical software engineering job description, including key skills, responsibilities, and salaries, in this online guide.

What Is a Software Engineer and What Does a Software Engineer Do?

Software engineers typically work in teams to build programs, platforms, and applications. While some software engineers can build both the front-end (user interface) and back-end (the code that makes the program functional), it’s not uncommon for engineers to develop a specialty in one or the other.

Software engineers can take their talent to almost any industry producing technology: video games, business solutions, mobile applications, and network control systems are all built by software engineers.
