Computer Programmers write, test, and verify code that allows digital programs and software to function. They turn the program designs by UI Designers and Software Engineers into code that the computer can read. The programs we use every day function as expected, thanks to the code written by a Computer Programmer.

Programmers can work on software that is designed for mobile, tablet, or computers. Depending on the industry and the company they work for, Programmers may also oversee bug testing, removing errors, and developing functionality updates.  

The primary responsibility of a Computer Programmer is to write code. To do so, they need to know at least one programming language. However, it is common for most Programmers to know a few programming languages since different programming languages are more suited to some contexts than others. 

Programmers usually work on teams, and often a more senior Programmer will review and test the code of a more junior Programmer to ensure that it functions properly.
