Senior Mechanical Engineer (Spacecraft Components and Systems)

• Muon seeks a Senior Mechanical Engineer to serve as a hardware expert in component design. You’ll own the mechanical direction of the component from requirements definition to installation on the launch vehicle
• This will include direct collaboration with Muon’s engineering teams to understand requirements, execute designs, deliver robust hardware, pulling in relevant stakeholders (such as structural, thermal, electrical, etc) at the appropriate times to deliver a satellite on-time
• Being an early-stage startup with a small team, breadth is extremely important and we expect this person to dive into structural analysis, dynamics, thermal design, supplier management, and everything else associated with the full lifecycle of an electromechanical product
• Have a deep understanding of Muon’s spacecraft platforms & capabilities. Tailor and develop components to these platforms to meet mission needs
• Design, build, and test mission specific components and payloads
• Create, analyze, and refine spacecraft system mechanical designs in SolidWorks
• Design & document new, reusable components to be included in Muon’s common platform
• Lead mechanical portion of both internal and external design reviews
• Interface with structural and thermal engineers to define and run analysis
• Lead component environmental testing campaigns (vibration, TVAC, etc)
• Write new documentation and build procedures unique to the mission

Benefits

• 100% health, dental, and vision coverage for employees; 50% coverage for dependents (Concierge Medical offered through One Medical where available)
• Parental leave for primary and secondary caregivers
• Generous time off policy
• 401(k) plan through Betterment and equity management through Carta
• Fully stocked kitchen at our HQ and we cater lunch 3 days per week
• Dog-friendly office- Proficiency in CAD (SolidWorks preferred) for component and assembly design
• Demonstrated proficiency leading mechanical design for complex electromechanical systems
• Experience technically leading or managing a small team of engineers and/or technicians
• B.S. or higher in Mechanical Engineering or related field
• Experience managing external vendors for part prototyping and development
• 8+ years of experience designing, building, and testing high reliability hardware
• Mastery of drawings, GD&T, BOMs, FAIs, tolerance budgets, and mass budgets
• Excellent communication, presentation, and cross-functional coordination skills
• Experience with ECO/DCO processes and PLM systems
• Extensive documentation capabilities: build procedures, test plans, design trades, DOEs
• Flight heritage—hardware you designed that has successfully operated in space
• Familiarity with satellite payloads and mission-level mechanical integration
• Experience optimizing and maturing existing designs (not only clean-sheet development)
• Experience with deployable hardware (solar arrays, antennas, mechanisms)
• Experience with ADCS components: reaction wheels, torque rods, star trackers
• Experience running structural analyses (FEMAP, ANSYS) & environmental testing
• Experience with thermal management systems for spacecraft
• Large assembly management in SolidWorks PDM; experience with PLM systems (Duro or similar)
• Project management experience: customer reviews, Gantt charts, risk tracking
• Software skills in Python, MATLAB, or similar
• Experience qualifying external vendors and contract manufacturers
• We encourage you to apply, even if you don’t check all the boxes, and we look forward to reviewing your application!
