Job description

We are seeking a Harness Design Engineer to own the complete lifecycle of electrical harness development for advanced spacecraft programs. This role combines electrical design, systems integration, and hands‑on hardware development, supporting missions from initial concept through fabrication, integration, and flight acceptance.

The ideal candidate will have experience designing aerospace‑grade wiring harnesses and enjoy working closely with electrical, mechanical, manufacturing, and integration teams to deliver reliable flight hardware. This is an opportunity to play a critical role in the development of next‑generation satellite systems operating in demanding space environments.

What You'll Do

• Design and develop spacecraft electrical harnesses from requirements definition through fabrication, integration, and acceptance testing
• Create and maintain harness design documentation, including wire lists, schematics, connector selections, drawings, and routing diagrams
• Author and maintain engineering specifications, manufacturing work instructions, and acceptance test procedures (ATPs)
• Support and lead harness fabrication efforts alongside manufacturing and technician teams, providing build support and resolving production discrepancies
• Perform and review electrical analyses, including wire sizing, voltage drop calculations, grounding and shielding strategies, and derating assessments
• Lead spacecraft harness integration activities, including continuity testing, pull testing, hi‑pot testing, and functional verification
• Drive continuous improvement initiatives through lessons learned, Design for Manufacturability (DFM) reviews, and failure investigations
• Work directly with suppliers and vendors to specify, procure, and qualify harness components such as connectors, wire, backshells, and associated hardware

What We're Looking For
