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.
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

Lead incidents as a senior incident commander in the on-call rotation, and serve as the escalation backstop when a case rises above the responders on call.
Own the 24/7 coverage model, rotation discipline, and response SLAs for your US region, keeping the program humane and the bar high at the same time.
Build and develop a team of senior incident responders, setting the on-call expectations and quality bar they operate to.
Drive executive, legal, and customer communications during declared incidents, including regulated reporting and disclosure timelines.
Own the joint operating relationship with Physical Security and Data Center Operations for incidents that cross cyber, physical, and OT surfaces.
Run the post-incident review cadence and drive remediation to completion across detection, response, and infrastructure.
Hold the bar on the agentic triage layer, defining what the agent escalates and feeding incident learnings back to detection engineering and threat intelligence.

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 led material incidents end to end as a senior incident commander at organizations with sophisticated, well-resourced threat actors.
You've managed and grown a team of senior responders while staying in the on-call rotation yourself.
You've designed or run a 24/7 on-call program: coverage models, rotation discipline, acknowledgement and response SLAs, and escalation chains.
You move between technical containment and executive, legal, or customer-facing communications during a declared incident without losing the thread.
You've made disclosure-grade calls under regulatory and customer reporting clocks.
You've built operating relationships across security, infrastructure, and physical or facilities teams, and led incidents that crossed those boundaries.
You have well-founded opinions on what makes an on-call program humane and an incident response process effective, and you're ready to build one from a small senior core.
