Harness Design Engineer

Location: San Jose, CA

Employment Type: Full-Time

Work Arrangement: Onsite

About The Role

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

Required Qualifications

What We're Looking For

Bachelor’s degree in Electrical Engineering, Aerospace Engineering, or a related technical discipline
2+ years of experience designing electrical harnesses for aerospace, spacecraft, defense, or other high-reliability systems
Hands-on experience with harness design tools such as OnShape, Altium, or similar platforms
Experience supporting hardware through build, integration, and test phases
Solid understanding of grounding, shielding, and EMI/EMC principles for complex electrical systems
Strong technical documentation skills, including specifications, engineering drawings, and manufacturing work instructions

Preferred Qualifications

Experience supporting LEO, GEO, or other spacecraft programs
Familiarity with aerospace wiring and connector standards, including MIL-DTL-38999, MIL-W-22759, NASA-STD-8739.4, or similar
Knowledge of NASA, ECSS, or equivalent aerospace workmanship standards
IPC/WHMA-A-620 certification or equivalent harness manufacturing certification
Experience working within AS9100 quality management environments
Familiarity with Product Lifecycle Management (PLM) or Product Data Management (PDM) systems

Why Join Us?

Contribute directly to the development of next-generation spacecraft and satellite systems
Own critical hardware from concept through flight-ready integration
Collaborate with multidisciplinary engineering teams in a fast-paced aerospace environment
Gain hands-on experience with cutting-edge spaceflight hardware and mission-critical systems
Play a key role in delivering reliable spacecraft that support Earth observation, communications, science, and exploration mission
