The posting, in Muon Space's own words
archived Oct 16, 2026About the role
Muon seeks a Mechanical Engineer to design and build hardware for our spacecraft platforms. Working alongside the group's senior and staff engineers, you'll take real ownership of components and assemblies: designing them, releasing them, prototyping them, and proving them out in test. This is a hands-on design role with a fast build-test-learn loop. You'll see your hardware go from CAD to flight, and you'll help carry designs from first prototypes through constellation-quantity production. This position is hybrid and requires working on-site in our San Jose, CA office three days per week.
What you'll do
Own the design of components and assemblies within a spacecraft subsystem, from concept through CAD, flight build, and test, Develop and document design options and trades, with guidance from senior engineers on approach. Present your designs at reviews and participate as a peer reviewer. Drive integration and test of your hardware, and troubleshoot issues through root cause during build, qualification, and mission operations. Partner with the dedicated structural and thermal groups on detailed analysis, and coordinate across adjacent disciplines to keep the vehicle integrated. Mentor engineers, raise the team's technical bar, and influence design standards and best practices beyond your immediate scope.
