About the role
Muon seeks a Principal Mechanical Engineer to join our Mechanical Engineering team, reporting to the Director of Mechanical Engineering. This role will be deeply technical with a focus on solving the most demanding design, analysis, test, reliability, and manufacturing challenges across multiple spacecraft platforms. This role will also have the opportunity to frequently be hands-on with both prototype and production hardware.
You will serve as a technical leader, mentor, and advisor to others on the mechanical team, leveraging previous experience in designing & building spacecraft to push boundaries and design industry leading "new space" satellites for many different commercial and national security applications. Additionally, you will help define product roadmaps & use a breadth of knowledge to make system level tradeoffs and optimizations.
This hybrid role requires onsite work at our San Jose location three days a week.
Responsibilities
- Serve as a technical advisor and domain expert, leading the team to optimal designs of spacecraft structures and components
- Identify opportunities and lead efforts to improve performance, reduce mass, lower cost, improve manufacturability of current spacecraft platforms.
- Interface directly with Muon's product & business teams to understand market needs define multi-year roadmaps for mechanical subsystems
- Act as a force multiplier by providing strong, hands-on mentorship to mechanical engineers at all levels, developing their technical skills and systems-level thinking
- Define mechanical team standards and best practices
- Contribute broadly to hiring, onboarding, and training of mechanical engineering talent, helping build a culture of technical excellence
Required Qualifications
- 12+ years of experience designing, building, and testing flight hardware in the space industry, with multiple programs through on-orbit operations.
- Strong mentorship experience with demonstrated success in developing junior and mid-level engineers & directly or indirectly leading a team of engineers.
- Proven track record of optimizing and maturing existing designs and proven approach to clean-sheet development
- Expert technical knowledge of structural mechanics and analysis, thermal management and modeling, environmental testing (TVAC, vibration)
- Experience with a variety of manufacturing methods and techniques for space applications, including machining, composites, molding, 3D printing, etc
- Mastery of standard tools: CAD (SolidWorks preferred), PLM, ERP, FEA, test hardware and equipment
- Expert-level skills with drawings, GD&T, BOMs, FAIs, tolerance budgets, and mass budgets
- Experience managing external vendors for part development and manufacturing
- Excellent communication, presentation, and coordination skills
- B.S. or higher in Mechanical Engineering or related field
Nice-to-have Skills
- Experience with deployable structures (solar arrays, antennas, mechanisms)
- Optomechanical instrument or payload design experience
- Software skills in Python, MATLAB, or similar
- Experience with reaction wheels, torque rods, star trackers, or other ADCS components
- Large assembly management in SolidWorks PDM, Duro, or similar PLM
- Experience running structural analyses (FEMAP, ANSYS)
- Track record of establishing engineering standards at an organizational level
Salary
The salary range for this role is $222,000 - $250,000, plus a competitive equity grant and comprehensive benefits package. Final compensation will be determined based on skills, qualifications, experience, and geographic location as assessed during the interview process.
