ABOUT FLUIDSTACK At Fluidstack, we build the compute, data centers, and power that will fuel artificial superintelligence. We supply GWs of compute capabilities to the world’s biggest AI Labs at industry-defining speeds. Our team is small, fast, and obsessed with quality. We own outcomes end-to-end, challenge assumptions, and treat our customers' problems as our own. No task is beneath anyone here. There are a few thousand people who will shape the trajectory of superintelligence. Come and be one of them. About the Role Frontier AI runs on bare metal — and the bare metal it runs on has to be trustworthy from the silicon up. As Fluidstack's Information Security Engineer for Bare Metal, you'll own the security of the physical fleet powering some of the most important AI workloads in the world. This is a deeply technical, hands-on role for an engineer who thinks in firmware, kernels, and packet flows, and who wants the rare opportunity to design fleet-wide security controls from a clean slate rather than inherit someone else's compromises. You'll work at the intersection of hardware, operating systems, and network security in an environment where performance margins are thin, customer trust is paramount, and the threat model includes nation-state-level adversaries. The systems you build will protect tens of thousands of GPUs and the workloads of customers whose models will shape the next decade of computing. What You’ll Own: - Fleet lifecycle security. End-to-end security for every server in our bare metal fleet — from supply chain and provisioning through hardening, operation, and secure decommissioning. - Hardened OS images. Design and maintain the golden images that run our production and development environments, including automated vulnerability scanning, patch pipelines, and configuration drift detection. - BMC security. Define and enforce the security model for baseboard management controllers: access control, credential rotation, audit logging, and firmware int
