About the role
About
the role Muon seeks a Staff Mechanisms Design Engineer to own the design, qualification, and sustainment of the deployable and actuated mechanical systems that power our spacecraft: solar array deployables, solar array drive assemblies (SADA), hold-down and release mechanisms (HDRMs), hinges, dampers, and latches. These are mission-critical, single-point-failure systems, and this role owns them from
requirements definition through qualification and on-orbit operation. As a foundational member of our new Solar & Deployables hardware group, the ideal candidate goes deep on
requirements definition, mechanism design, analysis, prototyping, qualification, and transfer to production while collaborating across disciplines to deliver high-reliability solutions. This position is hybrid and requires working on-site in our San Jose, CA office three days per week.
Responsibilities Serve as the technical owner for deployable and actuated mechanisms — SADA, HDRMs, hinges, dampers, and latches — setting architecture and design direction across missions Lead trades on deployable architectures and release-device technologies, making sound make vs. buy decisions that balance reliability, cost, and schedule Lead the design, analysis, and optimization of deployment mechanisms, actuators, and release devices, including torque/force margin, structural, kinematic, tribological, and dynamic analyses Own single-point-failure management for deployables, including margin, redundancy, and test-coverage strategy Own mechanism qualification campaigns, including deployment testing with gravity offload, lifecycle testing, and environmental test (random vibration, TVAC, shock) Define and champion mechanism design standards and best practices that scale across the organization Mentor mechanical engineers and lead rigorous design reviews (PDR, CDR, MRR) Drive mechanisms from prototype builds to constellation-scale production, applying lessons learned from builds, tests, and on-orbit operations
