Staff Spacecraft Platform Engineer

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
