Firmware engineer

A firmware engineer writes the low-level software embedded directly in hardware devices — the code that runs on chips and controls how a device behaves at the most fundamental level. They program in C and assembly, work within strict hardware and memory constraints, interface software with electronics, and debug at the boundary of code and circuitry.

The role is among the closest software gets to hardware, requiring electronics knowledge and meticulous, reliability-focused work since firmware bugs can be hard or impossible to patch. Firmware engineers work in consumer electronics, automotive, IoT, and industrial fields.

The job suits people who enjoy working at the lowest software levels and the precise, demanding craft of making hardware come alive.
