Computer programmers work in a wide range of industries, but generally in offices as salaried employees who code or write computer software and write, design, debug, troubleshoot, and maintain source code related to various computer programs. They also ensure that all source code is written in programming languages that can be understood by the computer so that programs can then be used by end-users. They may also customize computer programs which were purchased from vendors.
Computer programmers must know computer algorithms and application domains, and they may be required to work with vendors to test and approve their products. They must document the programs they write, and documentation should include charts, flowcharts, layouts, diagrams, and code comments and revision dates.
A bachelor's degree in computer science, information technology (IT), or a related field and prior work experience are generally required for this position, and some employers may prefer those who have a master's degree and research experience. Computer programmers must have thorough knowledge of Java/Java EE, C, C++, C#.NET, Java Script, and other programming languages relevant to the job, and strong written and verbal communication skills are also important. They must be able to work in a team environment and always stay up-to-date with new technologies and programming languages that become available. Some may have to travel to vendors' or clients' offices, attend relevant classes, workshops or conferences, or train and coach new computer programmers.
