Senior Propulsion Test Engineer
Axiom Space Inc., Houston, TX, United States
Axiom Space fosters a work environment inclusive of all perspectives. We are the pioneers of commercial space, leading the transformation of low-Earth orbit into a global space marketplace. Our mission-driven team is seeking a bold and dynamic We are seeking a resilient, high-energy Propulsion Senior Engineer - Test to own end-to-end test execution for a bipropellant engine/propulsion assembly—from translating requirements into test objectives and plans through test article integration, stand readiness, checkouts, hot-fire/qualification testing, anomaly resolution, and flight/acceptance readiness. You will lead cross-functional teams and suppliers to deliver safely to aggressive cost and schedule targets while maintaining rigorous configuration control, test discipline, and data integrity. The ideal candidate brings deep hands-on propulsion test operations experience, strong technical leadership, clear communication, and a bias for rapid, repeatable execution.**KEY DUTIES & RESPONSIBILITIES**Own end-to-end propulsion test execution, from requirements flow down and test strategy through test article integration, stand readiness, hot-fire/qualification/acceptance testing, anomaly resolution, and flight readinessLead and support test readiness activities (TRR/FRR) including hazard analyses, permit/compliance requirements, FMEA inputs, checklists, and go
