Power Electronics Hardware Engineer (all genders)

Your mission:
We are seeking a highly skilled Power Electronics Hardware Engineer (all genders) to design, develop, and validate high-performance power control and conversion hardware. The ideal candidate will have strong expertise in power electronics design, component selection, simulation, PCB design, testing, and will work closely with cross-functional teams to deliver reliable, efficient, and cost-effective power solutions.

Your Day-to-Day:
• Design and develop power electronics hardware including power distribution & protection units, solid-state power controllers and DC-DC converters.
• Capture requirements and manage them systematically in a traceable way.
• Create schematics, PCB layouts, and BOMs for power electronic systems.
• Perform circuit analysis, simulations, and design optimization (thermal, EMI/EMC, efficiency, reliability).
• Select and qualify power components such as Power MOSFETs, IGBTs, SiC/GaN devices, magnetics, and passive components.
• Lead prototype build, bring-up, debugging, and validation testing.
• Conduct failure analysis and implement design improvements.
• Ensure compliance with relevant safety and regulatory standards (UL, IEC, ISO, etc.).
• Collaborate with firmware, mechanical, manufacturing, procurement and quality teams.
• Support production ramp-up, manufacturing test development, and field issue resolution.
• Prepare and maintain technical documentation, test reports, and design reviews.

Your profile:
• Bachelor or Master degree in Electrical Engineering or related field.
• Strong background in power electronics theory and practical hardware design.
• Experience with electrical protection, power semiconductors, converter topologies and control methods.
• Proficiency in schematic capture and PCB design tools (e.g., Altium, OrCAD, KiCad).
• Hands-on experience with lab equipment (oscilloscopes, power supplies, power analysers, electronic loads).
• Solid understanding of electronics packaging, thermal management, EMI/EMC, and safety design.
• Ability to debug complex hardware issues independently.
• Experience with wide bandgap semiconductors (SiC, GaN).
• Familiarity with simulation tools (LTspice, PLECS, PSIM, MATLAB/Simulink).
• Knowledge of high-voltage and high-power systems.
• Experience with DO-254 process.
• Experience with aerospace & defence standards (DO-160, MIL-STD-810, MIL-STD-461, MIL-STD-704).
