## Description (the employer's text)

### 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

Be a barrel. Full autonomy. Own things end to end, take on scope without being asked, no permission required to operate outside your core role.

Insane urgency. We drive everything forward as fast as possible.

Reason from 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.

Build something that actually matters. If you're going to spend your time, spend it on something that matters to the world.

### 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.

The industry's playbook was written for one building at a time. Vendor-managed appliances, manual process, and standards that assume a security team walks the floor. None of that survives contact with what we're building, so we build what should exist rather than buying what does.

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

Build the infrastructure as code that stands up a site's entire security platform, so bringing on a campus is a pipeline run rather than a project.

Own CI/CD and the release path for the security stack, so every change reaches production tested, versioned, and reversible.

Automate the remediation the team would otherwise do by hand, and hold the line that anything done twice becomes code.

Build the package and patch pipeline that keeps a growing fleet current without a person touching a single host.

Get the automation in place ahead of the platform it serves, so on-call stays something a small team can carry as campuses multiply.

### 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 infrastructure as code that other people deploy from, and the systems that exist because your pipeline created them outnumber the ones someone built by following a runbook.

You've automated yourself out of work you used to do by hand, and you can name what the team stopped doing as a result.

You've owned CI/CD for infrastructure rather than applications, including how a bad change gets caught and rolled back.

You've automated Windows fleets, where the tooling is thinner and the ecosystem less forgiving than it is on Linux.
