About the Role

We are looking for a Spacecraft Test Engineer to own mechanical and environmental testing across the spacecraft development lifecycle, from early R&D and design de-risking through first-article spacecraft qualification.

This role sits at the intersection of spacecraft design, mechanical engineering, materials, environmental testing, and systems engineering. You will develop and execute tests that identify failure modes early, establish engineering margins through physical data, and ultimately demonstrate that our spacecraft are ready for launch.

This role will also drive first-article spacecraft environmental testing, including vibration and thermal vacuum testing. You will lead these campaigns from test planning and fixture/instrumentation development through execution, data review, anomaly resolution, and final test
