Axiom Space is building the world’s first commercial space station –Axiom Station. Serving as a cornerstone for sustained human presence in space, this next-generation orbital platform fosters groundbreaking innovation and research in microgravity, and cultivates the vibrant, global space economy of tomorrow. Today, driven by the vision of leading humanity’s journey off planet, Axiom Space is the principal provider of commercial human spaceflight services to the International Space Station and developer of advanced spacesuits for the Moon and low-Earth orbit.

Axiom Space is building era-defining space infrastructure that drives exploration and fuels a vibrant space economy that will empower our civilization to transcend Earth for the benefit of every human, everywhere.

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 Associate ,
Propulsion Test Engineer who is fueled by high ownership, execution horsepower, growth mindset, and driven to understand our world, science/technology, and life itself, for the benefit of all on Earth and beyond.

We are seeking a resilient, high-energy Propulsion Test Engineer 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.

• 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 readiness
• Serve as technical authority on test architecture and readiness, including instrumentation & DAQ, test stand interfaces/GSE, propellant loading/pressurization, chill down/thermal conditioning, purges/venting, ignition sequencing, controls, and safety systems
• Develop and maintain test plans, procedures, and verification matrices (ATP/OTP/qualification/acceptance), including success criteria, constraints, and configuration baselines
• Lead and support test readiness activities (TRR/FRR) including hazard analyses, permit/compliance requirements, FMEA inputs, checklists, and go/no-go criteria
• Lead and participate in test trade studies, instrumentation selection, stand upgrades, operating envelopes, control logic, acceptance limits and coordinate subassembly integration and fit checks
• Conduct test operations: briefings, procedural compliance, real-time decision-making, and safe conduct of hazardous testing
• Own anomaly response and closure: lead troubleshooting, root-cause investigations, corrective actions, and retest plans; drive disposition through configuration control
• Utilize analysis/modeling and test data reduction tools to predict performance, validate models, and ensure requirements compliance (transient performance, thermal limits, stability margins)
• Perform data reduction, correlation, and performance reconstruction — steady-state and transient — including model validation and requirements compliance verification
• Manage vendor and supplier interfaces for test hardware/GSE/DAQ/instrumentation on cost, schedule, manufacturing, calibration, and verification deliverables
