What Does an Entry-Level Computer Scientist Do?

As an entry-level computer scientist, your job is to help develop software for your client. In this role, you may help coordinate the flow of work between departments, provide feedback on the development of an application, work with an existing developer to learn coding techniques, study the programming environment, or set up a server. As a junior developer, your job isn't to create the software so much as learn how to make it. Companies typically use this job as an extended training period to prepare employees for larger assignments. These jobs go by several names, so you may need to apply for positions like an entry-level computer programmer or entry-level computer engineer.
