Because computers are so important to our lives, there is a constant need to develop new software. Computer software engineers apply computer science, engineering, and math to design, develop, and test software. (Computer hardware engineers design computer chips, boards, systems, modems, and printers.) Software engineers first analyze users' needs. Then they design, construct, test, and maintain the needed software or systems. In programming, or coding, they tell a computer, line by line, how to function. They also solve any problems that arise. They must possess strong coding skills, but are more likely to develop algorithms and solve problems than write code. Software engineers often work as part of a team that designs new hardware, software, and systems. A core team may have engineering
