• Collaborate with suppliers to deliver integrated and certifiable subsystems.
• Model electrical and power electronics systems in a high-fidelity Digital Twin to optimize hybrid mission profiles.
• Perform power electronics topology selection and trade studies.

Requirements

• At least 2 years of professional experience with power electronics components.
• Strong experience designing 800V+ high-voltage power electronics, including AC/DC inverters and DC/DC converters.
• Knowledge of high-voltage filter design, grounding analysis, protective-device coordination, and digital power conversion.
• Hands-on experience integrating propulsion or powertrain test stands, including instrumentation, controls, and mechanical assembly.
• Experience with Altium, Cadence or similar tools, SPICE circuit analysis, gate-driver design, oscilloscopes, and network analyzers.
• Experience with C/C++, Python, MATLAB/Simulink, or PLECS, plus knowledge of avionics communications, ARINC, CAN, Ethernet, microcontrollers, multicore processors, and firmware development.

Nice to have

• Knowledge of EASA CS-23/25 or FAA FAR Part 23/25 certification requirements.
• Experience with DO-178C, DO-254, DO-160, hardware design, and airworthiness.
• Knowledge of EMI/EMC physics, specifications, design practices, and mitigation strategies.
• Experience with MATLAB/Simulink auto-code generation.
• Leadership experience in cross-functional engineering teams.

Culture & Benefits

• Work within a propulsion team developing a hybrid-electric regional aircraft.
• Collaborate across mechanical, thermal, electrical, flight-control, and supplier teams.
• Contribute to the development of an aircraft targeted for type certification by the end of the decade.
