Job Description
To pursue our ambitious vision, we are looking for a Senior Power Electronics Engineer. In this role, you will design the power conversion electronics at the heart of a satellite power system — owning your subsystem end-to-end, from first calculations to flight hardware. Your Mission Will Be To
• Design and develop multi-kW-class DC/DC power converters for satellite power systems: semiconductor selection, gate drive circuits, power magnetics, and thermal management.
• Design isolated and non-isolated auxiliary and bias power supplies (buck, flyback, push-pull, LLC topologies), including magnetics selection, isolation requirements where applicable, and common-mode behavior in high-dv/dt environments.
• Design motor driver electronics for the actuation of deployable structures.
• Perform circuit simulation and analysis: switching losses, thermal modeling, worst-case analysis, and stability of control loops.
• Build, bring up, and validate prototypes in the lab: functional testing, efficiency and thermal characterization, EMC. Requirements
• Professional engineering education (MSc or equivalent) in electrical engineering / power electronics, with 5+ years of hands-on converter design experience.
• Solid theoretical foundation in power converter topologies, magnetics design, and control theory.
• Practical experience with wide-bandgap devices (SiC/GaN): gate driving, switching characterization, layout for high dv/dt environments.
• Strong analog design
skills:
sensing chains, amplifiers, comparators, protections.
• PCB design proficiency (KiCad) with focus on power layout and EMI mitigation.
• Autonomy in the lab: oscilloscopes, differential/isolated probes, power analyzers, electronic loads.
• Strong analytical skills, a proactive attitude, excellent interpersonal skills and unbounded curiosity.
• You enjoy owning your scope end-to-end.
• Professional level English — further languages welcome. Nice To Have
• Experience in space, automotive, aerospace, or other high-reliability industries.
• Familiarity with photovoltaic systems: solar cell/array characteristics, IV curve behavior, MPPT techniques.
• Familiarity with motor drives: stepper/BLDC control, driver stages, current regulation.
• Embedded C programming for real-time control on DSP/MCU.
