Muon Space, a LEO satellite constellation provider founded in 2021, is seeking a Staff Spacecraft Platform Engineer to own the spacecraft bus architecture—the reusable foundation underlying every mission. This is a senior technical role requiring deep systems-engineering expertise and cross-functional leadership.
You will own platform-level architecture and its evolution across the mission portfolio, partnering with Business Development, Product, and Engineering to align platform designs with product roadmaps and customer missions. Key responsibilities include leading cross-disciplinary system trades (mass, power, thermal, data, cost), developing platform requirements and flowing them down across subsystems, and serving as the technical authority bridging mechanical, electrical, avionics, thermal, and software domains.
You will drive reuse, modularity, and standardization to enable rapid mission configuration and reliable deployment. You'll set platform-engineering standards, lead platform-level design reviews, and resolve cross-subsystem interface issues. Additionally, you'll mentor engineers, raise the technical bar, and help hire and grow the platform team.
Required: 10+ years in spacecraft or complex-system engineering with system- or platform-level ownership. Broad understanding of spacecraft subsystems (structures, power, solar/deployables, mechanisms, avionics, thermal, GNC, comms) with deep expertise in at least one. Proven track record delivering spacecraft subsystems from requirements through design reviews, qualification, V&V, and flight operations. Experience leading system trades and requirements across multiple programs. Strong systems-engineering fundamentals (budgets, interfaces/ICDs, V&V) and technical leadership. B.S. or higher in Aerospace, Mechanical, Electrical, or related field.
Nice-to-have: Flight heritage with successful on-orbit platforms. LEO smallsat/ESPA-class platform experience. Experience defining reusable product platforms at scaling space companies.
The role is hybrid, requiring three days per week on-site in San Jose. ITAR/EAR compliance required.
