Computer hardware engineers typically do the following:
Many hardware engineers design noncomputer devices that incorporate processors and other computer components and connect to the Internet. For example, many car parts have computer systems embedded in them. Computer hardware engineers also are designing a growing number of medical devices with a computer system and the ability to connect to the Internet.
Computer hardware engineers ensure that computer hardware components work together with the latest software. Therefore, hardware engineers often work with software developers. For example, the hardware and software for a mobile phone frequently are developed jointly. Hardware engineers also may perform some computer programming in a hardware description language (HDL), which describes the digital circuits in hardware. Using this language, computer hardware engineers can simulate how the hardware design would work, test for errors, and then fix the design.
