About the role

Senior Harness Engineer responsible for end-to-end electrical interconnect system design, 3D harness routing, manufacturing coordination, and integration on Starcloud spacecraft.

Responsibilities

  • Own harness design from concept to flight
  • Drive the electrical interconnect architecture for spacecraft power, data, RF, and GPU/compute subsystems, including high-current power distribution for multi-kilowatt payloads
  • Produce complete harness designs: interconnect diagrams, wiring schematics, wire lists, connector and contact selection, wire gauge and derating analysis, shielding and grounding schemes, and bend-radius/routing constraints
  • Model 3D harness routing in CAD (NX, Creo, CATIA, or Siemens Capital/Zuken E3 for electrical), coordinating clearances, clamp locations, service loops, and keep-outs with the mechanical team
  • Define and release harness drawings, build books, from/to lists, and inspection criteria; manage revisions through release and ECO processes
  • Work as the bridge between EE and Mech
  • Partner with electrical engineers to capture pinouts, signal integrity and EMI/EMC requirements, power budgets, and connector interfaces from every avionics box and payload
  • Partner with mechanical and structures engineers on routing paths, mounting provisions, thermal environments, and vehicle access for assembly and rework
  • Own and maintain the interface control documentation (ICDs) for all electrical connections across the vehicle; catch interface mismatches before they reach the floor
  • Drive harness manufacturing to completion
  • Own the build plan: sourcing of wire, connectors, contacts, backshells, overbraid, and tooling; long-lead procurement; and kitting
  • Write build, crimp, solder, and inspection procedures to IPC/WHMA-A-620 (Space Addendum) and NASA-STD-8739.4 standards
  • Stand up and scale harness production, in-house or with contract manufacturers; train and support harness technicians; perform or sign off on first-article inspections
  • Be on the floor during builds to resolve issues in real time, disposition non-conformances, and implement fixes without stopping the line
  • Support integration, test, and flight
  • Support vehicle integration, continuity/hipot/insulation resistance testing, and functional checkouts
  • Own harness-related anomaly investigation and root cause, in test and on orbit
  • Feed lessons learned back into design standards, part libraries, and process documentation as we move from one-off builds to repeatable, rate production

Qualifications

  • Bachelor's degree in electrical, mechanical, aerospace engineering, or a related technical discipline
  • 3+ years of experience designing and building electrical wire harnesses for spacecraft, launch vehicles, aircraft, automotive, or similar high-reliability hardware
  • Hands-on experience taking a harness design from schematic through fabrication and installation
  • Proficiency in at least one 3D CAD package and one electrical/harness design tool

Skills

Required:Electrical harness design from schematic to fabrication3D CAD modeling (NX, Creo, CATIA, or Siemens Capital/Zuken E3 for electrical)Interface control documentation (ICD) ownership

Benefits

  • Lead Harness Engineer: $100,000 - $110,000 per year
  • Senior Harness Engineer: $140,000 - $190,000 per year
  • Potential for stock options, discretionary bonuses, and other long-term incentives.
  • Comprehensive medical, vision, and dental coverage.
  • 401(k) retirement plan with company match.
  • Short and long-term disability insurance, life insurance, and paid parental leave.
  • Generous paid vacation, holidays, and sick leave

About Starcloud

Data centers in space

(Formerly known as Lumen Orbit) Starcloud is building data centers in space, initially to provide GPU compute to other satellites, and later to address the rapidly growing demand for energy caused by the deployment of AI. Falling launch costs give us access to abundant energy, passive cooling, and the ability to rapidly scale in space. In Partnership with NVIDIA's Inception Program, we are launching our demonstrator satellite in late 2025, which will have 100x more powerful GPUs than have ever been operated in space.
