The Satellite Development Test Engineer responsible for transitioning satellite tests from engineer-driven ‘new product’ tests to routine, highly automated, efficient test processes that ensure every satellite off the production line is repeatably and robustly tested before shipping and launch. This role leads the development of end-to-end satellite qualification and acceptance test plans, then develops production test strategies, plans, procedures, automation, and supporting Ground Support Equipment (GSE) in preparation for handoff to a Production AI&T team to execute. The position works cross-functionally with Systems Engineering, Production AI&T, and all spacecraft subsystem teams (EPS, ADCS, Communications, C&DH, Flight Software, etc.) to meld verification requirements with real-world system performance variability and constraints into robust, executable test campaigns that minimize test-to-test variability and risk for human error.

This role is critical to enabling reliable and repeatable high-rate satellite production. The ideal candidate brings deep, hands-on experience from multiple spacecraft build and test campaigns and applies strong engineering judgment to develop test systems that minimize risk while maintaining efficiency. They are responsible for transforming early, engineering-driven test approaches into mature, production-ready systems that reduce operator variability, limit reliance on subject matter experts, and ensure consistent, high-confidence outcomes across every vehicle. This position is on-site in our Tukwila, WA office and reports to the VP, Spacecraft Engineering.
