Structural Analysis Engineer II

Position Summary

Do you want to make a difference immediately? Are you ready to apply your structural design, analysis, and testing skills to develop cutting edge life support and thermal control products for extreme environments on Earth and in space? Are you ready to play a critical role immediately? Can you excel in that team environment and carry your share of the load while also relying on others to do their part?

If this sounds like you, we want you to join Paragon Space Development Corporation now.

Paragon is developing exciting technologies, including spacesuits, lunar in-situ resource utilization (ISRU) systems, lunar dust mitigation, cryogenic fluid storage solutions, atmospheric revitalization for NASA's Lunar Gateway outpost, water recovery systems, and high-turndown morphing radiators.
