Muon Space is seeking a Mechanical Engineer II to design and build hardware for the Solar & Deployables group, responsible for solar arrays and deployable systems that power spacecraft. This is a hands-on design role with a fast build-test-learn cycle where you'll take real ownership of components and assemblies from concept through production.
Key responsibilities include:
- Design components and assemblies for solar arrays and deployable systems, including structures, mechanisms, and supporting hardware from concept through detailed design and release
- Produce and release engineering documentation: drawings, GD&T, BOMs, and tolerance stacks under configuration control
- Build and test prototypes to evaluate design concepts and retire risk early
- Support qualification and acceptance test campaigns, including deployment testing with gravity offload and environmental testing (vibration, TVAC)
- Perform first-order engineering analysis—margins, stiffness, and sizing hand calculations—to guide designs, working with analysts on detailed FEA
- Design test fixtures, GSE, and tooling to make hardware fast and repeatable to build and test
- Work with vendors on part fabrication and support build procedures and work instructions for production
- Present work in design reviews and incorporate feedback from senior engineers across disciplines
Required qualifications:
- 5+ years of experience designing, building, and testing mechanical hardware
- Strong CAD skills (SolidWorks preferred) for component and assembly design
- Solid command of drawings, GD&T, BOMs, and tolerance stacks
- Hands-on prototyping and test experience with a bias for learning through hardware
- Familiarity with common fabrication methods (machining, sheet metal, composites, additive)
- Excellent communication and teamwork skills in a fast-paced environment
- B.S. or higher in Mechanical Engineering, Aerospace Engineering, or related field
Nice-to-have skills include spacecraft hardware or deployables experience, structural analysis (FEA/hand calcs), environmental testing experience, composite design, PLM systems, and Python/MATLAB proficiency.
The role is hybrid, requiring three days per week on-site in San Jose. You'll see your hardware go from CAD to flight and help carry designs from first prototypes through constellation-quantity production.
