About The Role

Staff Spacecraft Platform Engineer

San Jose, CA

About the Role

Muon Space is hiring a Staff Spacecraft Platform Engineer to be a senior technical owner of our spacecraft bus — the reusable architecture behind every Muon mission. You'll own platform-level architecture and requirements, drive trades across mechanical, electrical, solar/power, thermal, and avionics, and keep the platform scaling cleanly as the mission portfolio grows.

This position is hybrid and requires working on-site in our San Jose, CA office three days per week.

Responsibilities

• Own spacecraft platform architecture and its evolution across the mission portfolio.
• Partner with BD, Product, and Engineering to ensure platform architectures align with product roadmaps and near‑term customer missions
• Lead cross-disciplinary system trades (mass, power, thermal, data, cost) and platform requirements development and flow-down.
• Understand the architecture levers that map the spacecraft HW architecture to system / mission performance.
• Serve as the technical authority bridging mechanical, electrical, avionics, thermal, and software.
• Drive reuse, modularity, and standardization so new missions configure quickly and reliably.
• Set platform‑engineering standards and lead platform‑level design reviews, resolving cross‑subsystem interface issues.
• Mentor engineers, raise the technical bar, and help hire and grow the platform team.

Required Qualifications

• 10+ years in spacecraft or complex‑system engineering, including system‑or​-platform‑level ownership.
• Broad understanding of spacecraft subsystems (structures, power, solar / deployables, mechanisms, avionics, thermal, GNC, comms), with deep technical knowledge / expertise in at least one spacecraft subsystem.
• Ownership and delivery of spacecraft subsystems from requirements through design reviews, qualification, V&V, and launch / flight operations.
• Track record leading system trades and requirements across multiple programs or product generations.
• Strong systems‑engineering mindset and fundamentals: budgets, interfaces / ICDs, V&V.
• Strong technical leadership and cross-functional communication.
• B.S. or higher in Aerospace, Mechanical, Electrical, or a related engineering field.

Nice-to-Have

• Flight heritage — platforms you architect that have successful on orbit flight heritage.
• Experience with LEO smallsat / ESPA‑class platforms.
• Experience defining a reusable product platform at a scaling space company.

Salary

The salary range for this role is $202,000 - $223,000, 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.
