A computer systems engineer develops, tests, and evaluates software and personal computers by combining their knowledge of engineering, computer science, and math analysis. The system engineer is expected to be capable of improving the equipment and current processes by integrating both software and hardware solutions as to produce a stable system that will meet the clients needs.

Computer engineering (CoE or CpE) is a branch of engineering that integrates several fields of computer science and electronic engineering required to develop computer hardware and software. Computer engineers usually have training in electronic engineering (or electrical engineering), software design, and hardware-software integration instead of only software engineering or electronic engineering. Computer engineers are involved in many hardware and software aspects of computing, from the design of individual microcontrollers, microprocessors, personal computers, and supercomputers, to circuit design. This field of engineering not only focuses on how computer systems themselves work but also how they integrate into the larger picture.
