We are seeking a versatile, high-impact Principal Engineer to lead the development of mission-critical hardware. This is a "full-lifecycle" role where you will own everything from the initial conversion of ambiguous concepts into rigorous requirements to the hands-on assembly and environmental qualification of flight hardware. You will also review and advise across mechanical programs, contribute to proposals, and serve as a senior technical resource for our growing team.
