Software Engineer Job Descriptions, Average Salary, Interview Questions

What Does a Software Engineer Do?

Software engineers design, develop, implement, and support software solutions for systems and applications. They create and implement software solutions for organizations using a wide variety of programming languages, tools, and platforms by applying principles of engineering and computer science.

Throughout the lifecycle of a piece of software, software engineers direct the processes of updating, patching, and repairing code. In addition to hard skills like expertise in software development, a software engineer also needs soft skills like communication, teamwork, and critical thinking. Software engineers often lead teams of developers, so the ability to communicate ideas to other group members — as well as customers, non-technical colleagues, and managers — is critical.
