Note: The job is a remote job and is open to candidates in USA. The space and defense company is hiring a Contract Power Electronics Design Engineer to own a spacecraft payload power design through a focused three-month engagement. The role covers end-to-end architecture, schematic capture, PCB layout direction, converter and magnetics design, simulation, high-reliability analysis, hardware testing, troubleshooting, and technical reviews.
Responsibilities
- Owning a payload power electronics design end to end — architecture, schematic capture, PCB layout direction and test
- Designing a phase-shifted full bridge DC-DC converter above 1800W, including the magnetics
- Transformer and inductor design — turns ratio, core and winding selection, thermal and loss budgets
- Running SPICE simulation to close loop stability, transient response and efficiency ahead of hardware
- Producing the high-reliability analyses: parts stress, worst case, derating and failure modes
- Supporting board bring-up, functional test and verification, and troubleshooting when hardware misbehaves
- Presenting the design and its margins at reviews, and writing it up so it stands on its own
Skills
- • Proven spacecraft or space-qualified power electronics design experience
- • Phase-shifted full bridge design experience at >1800W DC-DC
- • Transformer and magnetics design experience
- • Payload power architecture design
- • SPICE simulation and schematic capture through to PCB design (Altium or equivalent)
- • Strong analog and digital electronics fundamentals
- • Space hardware integration, test and verification knowledge
- • Sound engineering judgment — balancing risk and technology against requirements, cost and schedule
- • Exemplary written and oral communication, with a track record of presenting technical material
- • US-based and eligible to work on ITAR-controlled programs
- • High-reliability or Class A mission design standards, NASA, JPL, DoD or MDA programs
- • High-voltage, high-current work (100V+, 100A+), MPPTs, PDUs, batteries, motor controllers, solar arrays
- • Basic test-only firmware development
- • Energy balance modelling, power architecture trade studies and design review support
- • Prior contract or independent consulting work, you land and add value fast
Benefits
- 3-month contract
- 30 hours per week
- Fully remote (US-based)
