- Own full hardware development cycle including prototyping, testing, integration, and production deployment
- Conduct comprehensive verification testing and failure analysis for electrical power systems
- Collaborate with RF, mechanical, and systems integration teams to define power electronics requirements
- Perform electrical power system trade studies to optimize performance, efficiency, and reliability
- Rapidly iterate on designs and test results to inform product direction and system-level decisions
What they're looking for
- DC-DC converter design and topology selection
- High-voltage power supply design (kilovolt-level systems)
- Magnetics design including custom transformers and planar inductors
- Power electronics modeling and simulation
- Analog control and compensation design
- Failure mode and effects analysis (FMEA)
- Lab measurement techniques (impedance, loop-gain analysis)
- Embedded systems and telemetry integration
