- Ability to work effectively with cross-functional engineering, manufacturing, quality, supply chain, and test teams.
THESE QUALIFICATIONS WOULD BE NICE TO HAVE
- Experience developing spacecraft mechanisms, robotic manipulators, precision motion systems, actuators, gimbals, deployment systems, or similar high-reliability hardware.
- Experience supporting hardware through environmental testing, including vibration, shock, thermal-vacuum, or life testing.
- Experience with finite element analysis and interpretation of structural, vibration, or thermal test data.
- Experience taking a component or assembly from concept through fabrication, assembly, test, and production readiness.
- Experience with NASA, JPL, DoD, commercial space, or other high-reliability aerospace programs.
- Strong mechanical problem-solving skills and a practical, hands-on approach to hardware development.
This position may require prolonged periods of sitting, standing, walking, computer work, and occasional exposure to moderate levels of noise, dust, and fumes in production areas.

Level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience.
WHAT TO EXPECT
We’re on a mission to unlock the potential of space to improve life on Earth, but that’s not an easy task. It takes hard work, determination, relentless innovation, teamwork, grit, and an unwavering commitment to achieving what others often deem impossible. Our people out-think, out-work, and out-pace. We pride ourselves on having each other’s backs, checking our egos at the door, and rolling up our sleeves on all tasks big and small. We thrive under pressure, work to tight deadlines, and our focus is always on how we can deliver, rather than dwelling on the challenges that stand in the way.
