Senior Harness Engineer

Starcloud is building a network of data centers in space, starting at kilowatts and scaling to gigawatt capacity. Falling launch costs allow us to take advantage of the abundant energy, radiative cooling techniques, and ability to rapidly scale in space. Join our team, push the boundaries of the space economy, and be part of this pioneering effort to redefine the future of energy.

Starcloud is building data centers in space. By placing compute in orbit, we can draw on near-continuous solar power and radiate heat directly to space, unlocking a path to scaling AI compute that is not constrained by land, water, or terrestrial grids. Our first satellites are already flying GPUs in orbit, and our roadmap scales to multi-megawatt, then gigawatt-class orbital compute platforms. Every watt of power and every bit of data on our spacecraft travels through a harness. The Harness Engineer is the person who makes that system real.

As a Harness Engineer at Starcloud, you will own the electrical interconnect system of our spacecraft end to end: from architecture and connector selection, through detailed design and 3D routing, to build documentation, manufacturing, inspection, and integration on the vehicle. You will be the single point of accountability for getting harnesses designed, built, tested, and installed on schedule. This is a hands-on, full-lifecycle role. You will spend time in CAD, in design reviews with electrical and mechanical engineers, on the production floor with technicians, and in the integration bay with the vehicle. You will drive decisions, not wait for them.

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
