Contract Power Electronics Design Engineer — Spacecraft Payload Power

Contract Power Electronics Engineer — Spacecraft Payload Power

Open hourly rate

Contract - 40 hours per week

Fully remote (US-based)

An aerospace electronics manufacturer is hiring a Power Electronics Engineer to take a spacecraft payload power supply through to final flight design. You’ll own the design and analysis from current baseline through to flight.

The program is live. What’s needed is an engineer who has designed high-power converters for flight, backs every design with their own analysis, and can work remotely without waiting to be told what to do next.

What you’ll be doing

• Complete final flight designs for the spacecraft payload power supply, baselining Coilcraft CPS series magnetics
• Run EMI filter simulations to MIL-STD-461 CE101 and RE102
• Perform worst case circuit analysis per EEE-INST-002 Class 3 derating, using client-provided EOL parameters
• Cover parts stress, power dissipation, DC regulation, transient analysis and stability
• Provide power supply noise content data for the TCM and FPSM subsystems

✅ What you’ll need

• Degree in Electrical Engineering
• 8+ years of power electronics design experience
• Phase-shifted full-bridge DC-DC converter design above 1800W
• Transformer and magnetics design
• Payload power architecture design
• SPICE simulation, schematic and PCB design capture, electronic test and power supply design
• Analog and digital electronics, plus space hardware integration, test and verification
• Clear communication, including presenting technical material in design reviews
• US-based and eligible to work in the US

⭐ Nice to have

• Flight heritage on NASA or commercial spacecraft power systems
• WCCA, parts stress and FMECA experience on flight programs
• LTspice, PLECS, Altium Designer or Ansys Maxwell
• Prior contract or independent consulting work, so you can land and add value fast
