Contract Power Electronics Engineer

Contract Power Electronics Design Engineer — Spacecraft Payload Power

Open hourly rate

3-month contract – 30 hours per week

Fully remote (US-based)

A space & defense company is hiring a Contract Power Electronics Design Engineer to own a payload power design through a focused three-month push. Flight hardware for real missions, built to high-reliability standards, with the analysis rigour that goes with it.

 

The architecture is set, the program is moving. What’s needed is a design owner who has built spacecraft power boxes before, can pick up a live design without a long runway, and can carry it from schematic through layout and test on a fixed clock.

 

What you’ll be doing

  • 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

 

What you’ll need

  • 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

 

Nice to have

  • 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
