Contract Embedded Systems Engineers focus on designing and integrating hardware and software for embedded systems, often working with both hardware and firmware. Contract Firmware Engineers specialize in developing low-level software that runs directly on embedded hardware. While both roles require embedded systems knowledge, the embedded systems engineer has a broader scope including hardware design, whereas firmware engineers concentrate on software development within embedded environments.
