Contract Power Electronics Engineer — Spacecraft Power Systems

EVONA · United States (Remote)

Open hourly rate

6-month contract - 40 hours per week

Fully remote (US-based)

A space & defense company is hiring a Power Electronics Engineer to own board-level power design through a 6-month contract engagement. The hardware is power electronics for spaceflight systems, built to man-rated standard.

The architecture is set, the program is moving. What's needed is a design owner who has taken flight power electronics from schematic through qualification before, can pick up a live design without a long runway, and can carry it from capture through validation on a fixed clock.

What you'll be doing

• Take full ownership of a power board from requirements and architecture through to a qualified, flight-ready unit
• Design and simulate circuits across DC-DC conversion, solid-state switching, fault protection and current limiting
• Produce schematics and lay out multi-layer PCBs, working closely with mechanical on enclosure and packaging
• Bring up your own hardware on the bench and prove it out against spec
• Plan and run the qual campaign — vibe, shock, thermal cycling and vacuum testing
• Lead FMEA work and build the reliability case for your designs at system level

✅ What you'll need

• A degree in electrical engineering
• Solid hands-on background designing and delivering power electronics hardware
• Comfortable owning schematic and layout yourself, not just reviewing someone else's
• Circuit design depth in conversion, switching, protection and conditioning
• Bench skills — simulation tools, scopes, DAQ and test instrumentation
• Familiar with common embedded comms buses and serial interfaces
• Can script or code when the job needs it (Matlab, Python, C)
• Happy making calls with partial information and defending the reasoning
• Clear communicator, in writing and in the room
• US-based and eligible to work on ITAR-controlled programs

⭐ Nice to have

• Hardware you've designed has flown, or been through environmental qual for flight
• Experience taking a product from concept through production
• Data logging and SQL
• Formula SAE or similar student engineering team background
• Prior contract or independent consulting work, you land and add value fast
