Both software engineering and computer science involve computer software, including software development and other related fields. Individuals who are interested in a career in software development and computer technology often focus on one of two majors: computer science or software engineering (sometimes referred to as software development, but the two are not synonymous).

The primary difference is computer science was originally a sub-branch of mathematics. Computer science deals with the basic structure of a computer and is more theoretical, so it is more malleable in terms of specialization, with an emphasis on math and science. Software engineering is a field concerned with the application of engineering processes to the creation, maintenance, and design of software for a variety of different purposes. A software engineer designs customized applications per the requirements of an organization.

One of the main benefits of these vocations is that they offer the freedom of freelance engineering. With the increasing popularity of the gig economy, computer scientists and software engineers can reap the benefits as a freelance or contract worker.
