Xona develops satellite navigation services delivering positioning, navigation, and timing data via a Low Earth Orbit network. Backed by NGP Capital.
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.
What they're looking for
- Develop spacecraft-level verification strategies that connect early R&D testing with formal qualification and acceptance testing
- Define test objectives, success criteria, instrumentation, and data requirements
- Support PDR/CDR and other design reviews by providing test-derived evidence of mechanical and environmental performance
- Develop and maintain test plans, procedures, reports, and verification documentation
- Lead test readiness reviews and coordinate closure of test prerequisites and open technical issues
- Support qualification, acceptance, and flight hardware testing throughout the spacecraft lifecycle

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...
