Power Electronics Engineer

How will you contribute to IENAI SPACE?

As Power Electronics Engineer, your mission will be to develop and optimize high-voltage power electronics for the ATHENA Nano and Pico thrusters. Join our dedicated team as we work to refine this high-voltage converter into a robust, mature, and fully space-qualified device.

Your key responsibilities will include:

• Advanced design of switched-mode power supplies (SMPS): architecture definition, high-voltage design and optimization of thermal and electromagnetic performance.
• Simulation and analysis: use of advanced tools to model and simulate power circuits, parasitic effects and power integrity.
• Component selection: identify and select optimal components for performance, efficiency and reliability.
• PCB design: design multilayer PCBs using Altium Designer, with attention to high-voltage clearances, parasitics and planar transformer integration.
• Thermal and EMC design: perform thermal calculations, simulations and electromagnetic compatibility (EMC) pre-compliance testing.
• Testing setup and lab work: design, plan and execute complex in-house tests (thermal pre-qualification, EMC pre-compliance, etc.).
• Confident in EEE lab environments: circuit debugging, diagnostics and use of lab instrumentation (oscilloscopes, power analyzers, etc.).
• Skilled in SMD soldering and hands-on prototyping.
• Documentation and reporting: produce detailed technical reports, schematics, test documentation and progress updates.
• Collaboration: work closely with multidisciplinary teams to ensure integration with propulsion systems and mission requirements.
