91 Facilities Manager

Own the day‑to‑day operation, maintenance, and compliance of our London site as the single point of accountability for everything the building needs to function. Establish and manage our health and safety framework from first principles, including COSHH compliance, risk assessments, incident reporting, and safe systems of work. Manage all contractors on‑site onboarding, permits to work, supervision, and sign‑off ensuring work is delivered safely and to standard. Liaise with and support our on‑site security teams, coordinating access control, visitor management, and site security procedures. Own reactive and planned maintenance across the building, rolling your sleeves up for hands‑on tasks and escalating specialist work where needed. Provide logistical support across the business deliveries, internal moves, equipment set‑up, and space management as we scale. Manage COSHH substances, hazardous materials storage, and associated documentation with precision and accountability. Keep facilities documentation, compliance records, and contractor registers accurate and audit‑ready at all times. Identify and flag risks early to people, operations, or the site and take initiative to resolve them without being asked.

Who You're: An experienced facilities professional with a track record of managing buildings, contractors, and H&S compliance in a hands‑on role. COSHH certified, with real applied experience managing hazardous substances in a working environment not just the paperwork. Qualified to IOSH Managing Safely or NEBOSH General Certificate standard, with a thorough working knowledge of UK H&S legislation. Experienced managing contractors on‑site, including issuing permits to work, conducting inductions, and holding third parties to standard. Practically capable and comfortable picking up tools, diagnosing faults, and completing minor maintenance tasks yourself. Someone who has operated in a secure or access‑controlled environment and understands the discipline that requires. Discreet and security‑conscious by nature, able to work with sensitive information and people without needing to be told how to behave. A self‑starter who identifies what needs doing and does it without waiting for a process document or a prompt from above. Able to balance compliance rigour with start‑up pace, making sound judgement calls when the situation is ambiguous or fast‑moving.

What We Offer: A mission driven environment with the opportunity to work on one of Europe’s most consequential defence challenges, with direct impact on sovereign capability and security. Daily collaboration with top experts across engineering, operations, and defence, with real opportunity to learn from the best, contribute, and grow. High ownership and autonomy; no time tracking, no micromanagement, just clear objectives and accountability for outcomes. A fast paced environment where good ideas are implemented quickly, and feedback from test and flight drives real decisions. A culture that values clarity, integrity, and excellence, and supports people who take initiative and push boundaries responsibly. Competitive compensation and real share options aligned to responsibility and impact, not tenure or hierarchy.
