Mechanical Engineer II — Solar Arrays & Deployables

Climactic; San Jose (CA); Hybrid; USD 144,000 - 177,000; Full time

Job summary

Muon Space is seeking a Mechanical Engineer II to design, prototype, and release hardware for solar arrays and deployable systems destined for space. You will own components from CAD to flight, with a fast build-test-learn loop and collaborative work with senior engineers.

The role emphasizes hands-on prototyping, detailed drawings, GD&T, BOMs, and tolerance analysis, while collaborating across disciplines to bring hardware to production readiness in a hybrid on-site setting in San Jose, CA.

Qualifications

• 5+ years of experience designing, building, and testing mechanical hardware.
• Solid 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.

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
