  • Experience in one of the following domain areas: Cryogenic systems
  • Pressurized systems
  • Mechanical moving assemblies
  • Fluid Systems
  • Hands-on composites manufacturing experience
  • Hands-on metallic fabrication 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.
