Job summary

Muon Space is seeking a Mechanical Engineer II to own end-to-end mechanical execution for spacecraft missions from design through environmental testing and delivery to the launch vehicle. You will work with senior engineers and dedicated analysis teams, tailoring platform components to mission needs and creating mission‑specific hardware.

The role requires 5+ years in mechanical hardware design for complex systems, CAD proficiency (SolidWorks), and strong GD&T and documentation skills.

Qualifications

• 5+ years of experience designing, building, and testing mechanical hardware for complex systems.
• Experience taking hardware from concept through build and test.
• Structural analysis fundamentals: hand calculations, margin assessment, and familiarity with FEA
• Proficiency in CAD for medium‑to‑large assembly design and management (SolidWorks preferred)
• Solid command of drawings, GD&T, BOMs, and tolerance/mass budgets
• Excellent communication and cross‑functional coordination skills
• A strong desire to learn and contribute in a fast‑paced, dynamic environment
• B.S. or higher in Mechanical Engineering or related field

Responsibilities

• Own the mechanical execution of an assigned mission end-to-end — from requirements through design, build, integration, and environmental test — with support from senior engineers
• Tailor Muon's platform components to mission needs and design new mission‑specific components and payload accommodations
• Create and manage spacecraft‑level mechanical assemblies in SolidWorks, including envelopes, interfaces, and configuration control
• Perform first‑order structural and thermal sizing to guide your designs, partnering with Muon's dedicated structural and thermal analysis groups for detailed analysis
• Produce and release engineering documentation: drawings, GD&T, BOMs, and tolerance/mass budgets through ECO/DCO processes
• Support environmental test campaigns (vibration, TVAC) and spacecraft integration alongside production and test teams
• Write build procedures and support hardware assembly and integration on the floor
• Present your work in design reviews (PDR, CDR, MRR) and coordinate across systems, thermal, avionics, and payload teams
