What Does a Software Engineer Do

In this article

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.

What Qualifications Do Entry-Level Software Engineers Need?

In order to qualify for an entry-level software engineering job, aspiring candidates will need to be proficient in at least one programming language and have a fundamental understanding of the software development process. Knowing your way around multiple programming languages is the easiest way to showcase your skills during a software engineering job interview.

Below is a list of the most popular programming languages used in many software engineering jobs:

  • Python
  • JavaScript
  • Java
  • C#, C, and C++
  • Ruby
  • PHP
  • R

However, having good communication skills as well as an aptitude for logical thinking and problem solving will make the difference between a good and a great software engineer.

Code reviews are a crucial part of every software engineer’s journey, and having the ability to not only develop solutions but also explain their logic and reasoning to peers and team leaders is highly important. A synergistic result of both sets of skills results in an excellent ability to make tests—and know how to use them to iterate around new solutions.

What Are the Key Skills of a Software Engineer?

Software engineers always have a very wide range of skills. While technical proficiency in a programming language is usually listed as a core competency, software engineers often also need coding-adjacent skills that help their teams set benchmarks, establish tests, and innovate on existing systems. Because of the iterative nature of software engineering roles, candidates should also come equipped with interpersonal skills.

While software engineers job specs will vary across different industries, most hiring managers focus on:

  • Technical skills. Every software engineering job profile will include a series of hard skills, including knowing how to build software, tests, and code reviews, and using a programming language.
  • Interpersonal and collaborative skills. Software engineers will always be working in teams as they build, test, and deploy solutions through various environments, so collaboration is key. Most software engineer role descriptions will mention excellent organizational skills and a roll-up-your-sleeves work ethic.
