Additional Information

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.
