An embedded system is an electronic and software assembly built into a piece of equipment to perform a specific function, often under strong constraints on size, power consumption, reliability and real-time behavior.
They are everywhere: car control units, aircraft flight controls, satellites, drones, medical devices, industrial robots, connected objects. The core is usually a microcontroller, a processor or an FPGA, programmed in C, C++ or increasingly Rust, sometimes with a real-time operating system. The software has to talk directly to the hardware: sensors, communication buses, actuators.
In critical sectors (aerospace, defense, rail, medical), development follows strict safety standards such as DO-178C or ISO 26262, with extensive testing and traceability.
Why it matters when hiring
"Embedded" covers very different jobs: the electronics engineer who designs the board, the low-level developer who writes drivers, the application software engineer on embedded Linux, the systems engineer. Specify the target layer before searching. The good signal: projects on real hardware, debugging with an oscilloscope, experience in a regulated environment if your sector requires it. The talent pool is tight in defense and aerospace.
