In this role, you will be responsible for designing, building, and maintaining the hardware-in-the-loop (HITL) testbeds that serve as the primary proving ground for every satellite we build and fly. You will collaborate with nearly every engineering team — Flight Software, Guidance Navigation & Control, Avionics, Power, Payload, and Mission Ops — to ensure our testbeds are flight-representative, reliable, and always ready to support testing.

If it runs on a satellite, it gets proven on HITL first.

Role Own the full lifecycle of flatsat and HITL testbed builds, from initial design and BOM development through hardware procurement and software bring-up Scope and design harnessing needs, coordinating with manufacturing to produce custom harnesses for flight-like hardware

Serve on a rotating on-call point of contact for testbed health, triaging anomalies and managing access for other engineers

Diagnose and resolve hardware and software failures on the testbed, spanning firmware interfaces, flight software, and physical components

Drive testbed architecture decisions, including hardware allocation tradeoffs and risk mitigation for testbed contention

Expand simulation capabilities as new satellite blocks come online, integrating motor emulators and deployment simulators

Develop tooling to improve testbed observability, monitoring, and automated operations
