Embedded Systems Developer
For those who find magic in making software talk to hardware — embedded developers program the smart devices, sensors, and controllers that are connecting the physical world to the digital one.”
About This Role
Specializes in programming microchips that control smart appliances, vehicles, and medical devices.
A Day in the Life
Embedded Systems Developers write software for microcontrollers and specialised hardware — programming devices like IoT sensors, automotive ECUs, medical instruments, and industrial equipment in C/C++ with strict real-time and resource constraints.
- Write bare-metal C/C++ code for microcontrollers (STM32, ESP32, PIC)
- Develop and debug RTOS-based firmware (FreeRTOS, Zephyr)
- Implement device drivers for peripherals (UART, SPI, I2C, CAN)
- Interface hardware with oscilloscopes, logic analysers, and debuggers
- Write unit tests for embedded code (Unity, Ceedling)
- Review PCB schematics and collaborate with hardware engineers
- Optimise code for memory footprint, power consumption, and timing
Work Environment
Electronics company, industrial automation firm, automotive supplier, or IoT startup. Lab environment with test hardware and electronics equipment.
Typical hours: 45h/week · WLB score 7/10 · OCCASIONAL overtime
Hardware prototype deadlines and production issues can require extended hours. Generally good WLB in steady-state development.
