Staff Mechanical Engineer (Spacecraft Components)

Join Muon, an early-stage space technology company, as a Staff Mechanical Engineer. In this role, you will be the technical owner for spacecraft mechanisms and components design, manage single-point-failure, and oversee component qualification. You will work across engineering, production, and program management, and own the mechanical direction of your spacecraft component or mechanisms from requirements definition through design, build, test, and launch-vehicle integration. You will also lead design reviews, environmental test campaigns, and contribute to maturing Muon's mechanical engineering standards and culture.

• Assumer la responsabilité technique de la conception des mécanismes et des composants des engins spatiaux, en gérant les points de défaillance unique.
• Diriger la portion mécanique des revues de conception internes et externes, et diriger les campagnes d'essai environnemental des composants/sous-systèmes.
• Établir l'architecture mécanique au niveau de la plateforme, définir des campagnes d'essai complexes et posséder des conceptions sur plusieurs missions concurrentes.

• The ideal candidate can go deep on design while carrying a "systems mindset" — a force multiplier who collaborates across disciplines to arrive at an elegant, well-balanced design
• Excellent communication, presentation, and cross-functional coordination skills
• Customer-facing experience: technical interchanges, requirements discussions, or proposal contributions
• Demonstrated experience creating technical documents (ESOW, Technical Specification, DFMEA, Test Verification Plan)
• Proficiency in CAD (SolidWorks preferred) for medium-to-large assembly design and management
• Demonstrated proficiency leading mechanical design for complex electromechanical systems
• B.S. or higher in Mechanical Engineering, Aerospace Engineering, or a related field
• Experience owning a components used across platform, product line, or major subsystems
• 10+ years of experience designing, building, and testing high-reliability hardware
• Mastery of drawings, GD&T, BOMs, FAIs, tolerance budgets, and mass budgets
• Strong mentorship skills
• Recognized depth in a specialty (e.g., Mechanisms, Composites, or Dynamics) with industry references
• Experience with ECO/DCO processes and PLM systems
• Experience managing external vendors for part prototyping and development
• Extensive documentation capabilities: build procedures, test plans, design trades, DOEs
• We encourage you to apply, even if you don't check all the boxes, and we look forward to reviewing your application!
• Software skills in Python, MATLAB, or similar
• Experience running structural analyses (FEMAP, ANSYS, NASTRAN) and environmental testing
• Familiarity with satellite payloads and mission-level mechanical integration
• Experience optimizing and maturing existing designs (not only clean-sheet development)
• Large-assembly management in SolidWorks PDM; PLM systems (Duro or similar)
• Flight heritage on the following components: Gimbaled Devices, Separation/Launch Interface, Electrical Modules, Battery Packs, Reaction Wheel, CMG, Magnetorquer, Star Trackers, Propulsion, Radiators, Instrument Packaging, Instrument Scan Mechanisms
• Qualifying mechanisms to NASA-STD-5017, ECSS, or equivalent
• Experience with thermal management systems for spacecraft
