Director of Security

About Fluidstack We exist to make humanity more free. For most of human history, you farmed or you starved. Technology gave people more time for the things they wanted to do, instead of things they had to do. Powerful AI will be the biggest lever for human choice we've ever built - but only if models are aligned with what humanity actually wants. There are groups building AI who don't share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it. We're singularly focused on delivering 10 to 100s of GWs of compute faster than anyone else, rethinking every layer of the stack. We acquire power, design and build data centers, and operate them - with teams spanning hardware and software. Speed and scale are our key differentiators. Come be a part of building civilization-scale infrastructure for AI. We hire people who care deeply about this problem space. If that is you, please apply! How We Operate High ownership. Full autonomy. Own things end to end often taking on scope outside your core role without being asked to get things done. Velocity. We drive everything forward as fast as possible. First principles. Challenge every assumption. Zero analogy thinking, no egos, the best idea wins. Love of the game. The frontier of AI is the most interesting problem of our time. We put in long hours at high intensity to push the frontier forward. The Security Team Examples of key problems the team is working on You're securing the frontier of AI. The model weights training on our infrastructure are the most valuable and most targeted artifacts in technology, and we're standing up the compute to hold them faster than anyone ever has. A breach isn't a leak, it's the frontier walking out the door. Build the entire security program from scratch. Most leaders inherit someone else's system and spend a career patching it. Here you own it end to end, bare metal to boardroom, as we scale across continents. Your threat surface is measured in gigawatts. The customers running on our infrastructure are building the most consequential technology in human history, and being responsible for the physical and logical security of that work makes everything else feel small. Role Scope Own Fluidstack's global physical security program end to end: standards, policies, roadmap, and execution across a growing multi-site, multi-jurisdiction portfolio. Architect and govern ESS, ACS, and VMS deployments across greenfield builds and operational sites. Lead the GSOC buildout and partner with the cyber-physical and detection engineering functions. Partner with construction and site teams on security requirements from pre-RFS through operations, and manage guard force vendors, systems integrators, and technology vendors, including MSA/SOW negotiation and performance governance. Own physical security control evidence for SOC 2, ISO 27001, FedRAMP, and customer security schedules, and interface with customer security teams during audits, site inspections, and due diligence. Conduct site assessments, threat and vulnerability reviews, and drive remediation. This is a leadership role with real hands-on work as you build the program: deployment support, vendor walk-throughs, resolving an alert, checking the video. What We're Looking For The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would. You've built or run physical security programs for data centers, critical infrastructure, or large-scale industrial facilities, and you know what good looks like at scale. You've stood a program up from early stage and owned both data center and corporate spaces. You understand cyber-physical convergence deeply. This is more than gates, guards, and guns. You have deep hands-on expertise with enterprise ESS, ACS, and VMS platforms (Lenel, Software House, Genetec, Milestone, Avigilon, or equivalents), and you can read and contribute to security design drawings and construction documents. You've managed guard force vendors and systems integrators across multi-site environments with strong contract governance, and you know GSOC operations: alarm management, tooling integration, and escalation. You communicate clearly and concisely with executive leadership and customer security teams, and you'll travel 30 to 40% to Fluidstack offices and sites. Bonus: AI data center infrastructure. CPP, PSP, or CISSP. Threat, vulnerability, and risk assessments. Commissioning experience.
