- Real-time embedded systems and timing-sensitive applications

- Strong debugging skills using JTAG, oscilloscopes, logic analysers or similar

- Experience taking firmware beyond prototyping into robust production systems

- Comfortable working closely with electronics and control engineers

Desirable:

- ARM-based microcontrollers

- Motor control, power electronics or other real-time control applications

- CAN and other embedded communication protocols

- Bootloaders and firmware update mechanisms

- Safety-critical or high-reliability embedded development

- Automated hardware / firmware testing

- Hardware-in-the-Loop (HIL) testing

- MATLAB / Simulink or Model-Based Design exposure

- Aerospace, robotics, automotive or other high-performance embedded systems

Additional Information
