Responsible for mechanical and environmental testing of spacecraft throughout development, ensuring spacecraft readiness for launch through rigorous testing and data analysis.
Обязанности
- 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 reporting.
- The ideal candidate is equally comfortable developing a novel coupon test in the lab, working directly with a spacecraft on the integration floor, troubleshooting a test setup, and presenting test results across teams.
Требования
- 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.
- Drive lessons learned from testing into spacecraft design standards, manufacturing processes, and future vehicle builds.
- Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a related field.
- 3+ years of relevant engineering experience , with demonstrated ownership of hardware testing and verification.
- Experience developing and executing mechanical or environmental tests on complex hardware.
- Direct experience with one or more spacecraft environmental tests such as vibration, thermal vacuum, thermal cycling, shock, or structural testing .
- Strong understanding of mechanical engineering fundamentals, including structural mechanics, materials, thermal effects, fasteners, joints, and interfaces.
- Experience developing test fixtures, instrumentation, and data acquisition systems.
- Ability to interpret test data, identify anomalies, and perform root-cause analysis.
- Strong technical writing skills and experience producing engineering test plans, procedures, and reports.
- Ability to work hands-on with flight hardware and test equipment.
- Strong communication skills and the ability to work effectively across multiple engineering disciplines.
- Demonstrated ability to take ownership of ambiguous problems and drive them to completion.
