Director, Real Estate & Facilities

About the role Muon seeks a Director of Facilities to lead the team responsible for the infrastructure that our spacecraft are designed, built, and tested on. You will own the strategy, capital plan, and day-to-day performance of every facility Muon operates — from cleanroom and AIT space to environmental test infrastructure, critical power and process utilities. This is a hands-on executive role: you will set multi-year site and capacity strategy with the leadership team, defend and manage a capital and operating budget, and then personally drive the projects and vendor relationships that deliver it. You will build and develop the facilities engineering and maintenance organization and act as the single accountable owner for facility uptime against an aggressive spacecraft production ramp. Success in this role looks like spacecraft production never waiting on the building. This position is fully onsite and requires working in our San Jose, CA office five days a week. Responsibilities Build and maintain the multi-year facilities and site strategy for Muon, translating spacecraft production rate targets and program roadmaps into infrastructure and real estate requirements, and presenting those plans and their tradeoffs to the executive team. Build, lead, and develop the facilities organization, including facilities engineers, maintenance technicians, and contract staff. Set performance expectations, grow technical depth on the team, and establish on-call and escalation structures. Partner with Manufacturing, AIT, Test, Quality, Growth, IT/Security, and People Operations to ensure facility design and operations support production flow, cleanliness requirements, and a safe, high-quality work environment. Own the facilities capital and operating budget end-to-end, including forecasting, business case and ROI development for proposed projects, prioritization across competing program needs, and accountability for spend against plan. Serve as executive sponsor for major capital projects — cleanroom build-outs, environmental test installations, utility expansions, and site activations — making scope, schedule, cost, and risk tradeoff decisions. Define and own the reliability strategy for all facility infrastructure, including preventive and predictive maintenance programs, criticality ranking of assets, spares strategy, and redundancy decisions. Establish and report facilities KPIs — uptime, deferred maintenance, project delivery against baseline, and operating cost per square foot — to the team and to executive leadership on a regular basis. Lead the process to source, negotiate and manage contracts and performance for architects, general contractors, MEP design firms, commissioning agents, and service vendors; hold vendors to Muon's technical standards and commercial terms. Develop the code compliance posture of Muon's sites, including permitting strategy with local authorities, occupancy and inspection close-out, hazardous materials management, and environmental compliance. Develop the business continuity and emergency response plans for Muon's facilities, including readiness procedures for seismic events, power loss, and other environmental threats. Qualifications Bachelor's degree in engineering, other technical discipline or equivalent experience. 10+ years of professional experience in facilities engineering, infrastructure, or plant operations, including 5+ years leading and developing teams. Demonstrated ownership of large capital expansion projects from business case through commissioning and close-out, with accountability for multi-million dollar budgets and schedule commitments. Experience setting infrastructure strategy for a manufacturing organization scaling production rate, and communicating that strategy and its tradeoffs to an executive audience. Strong familiarity with MEP and HVAC building systems, including electrical and power distribution, critical power infrastructure, chillers, pl…
