Mechanical Engineer II, Solar & Deployables
About The Position
Muon seeks a Mechanical Engineer to design and build hardware for our new Solar & Deployables group — the team responsible for the solar arrays and deployable systems that power our spacecraft. 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.
Requirements
- 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, or additive)
- Excellent communication and teamwork skills, with a strong desire to learn in a fast-paced environment
- B.S. or higher in Mechanical Engineering, Aerospace Engineering, or related field
Nice To Haves
- Experience with spacecraft hardware, deployables, or precision mechanisms
- Structural analysis experience: hand calculations or FEA (FEMAP/NASTRAN, ANSYS, or similar)
- Experience with environmental testing (vibration, TVAC, shock)
- Composite panel or bonded-joint design experience
- Experience with PLM systems and ECO/DCO processes
- Software skills in Python, MATLAB, or similar
Responsibilities
- Design components and assemblies for solar arrays and deployable systems — structures, mechanism components, 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 test (vibration, TVAC)
- Perform first-order engineering analysis — margins, stiffness, and sizing hand calcs — to guide your designs, working with the group's analysts on detailed FEA
- Design test fixtures, GSE, and tooling that 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 your work in design reviews and incorporate feedback from senior engineers across disciplines
Benefits
- medical, dental, and vision insurance
- a 401k retirement plan
- short & long term disability and life insurance
- three weeks paid vacation
- 12 paid holidays
- unlimited sick time
- paid parental leave
