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 weve ever built - but only if models are aligned with what humanity actually wants. There are groups building AI who dont share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it.

Were 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

• Extreme 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

• Youre securing the frontier of AI. The model weights training on our infrastructure are the most valuable and most targeted artifacts in technology and were standing up the compute to hold them faster than anyone ever has. A breach isnt a leak its the frontier walking out the door.

• Build the entire security program from scratch. Most leaders inherit someone elses 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 incident response end to end across corporate cloud and data center environments from detection and containment through eradication and post-incident review.

• Build the detection logic response playbooks and forensic tooling for an environment where the assets under threat are the most targeted model weights in technology.

• Run investigations across a threat surface measured in gigawatts correlating signals from cloud endpoint network and physical systems into a single picture of an attack.

• Stand up the incident response function from the ground up defining severity models on-call rotations and the escalation path to leadership.

• Turn each incident into a permanent improvement by partnering with the security and IT teams to close the gaps your investigations surface.

What Were Looking For

• The below is a starting point. We always make space for exceptional people so if you dont fit this role exactly tell us where you would.

• Youve personally led major security incidents from first alert to resolution making containment calls under pressure with the business watching.

• Youve built detection logic and response playbooks that caught real intrusions not just theoretical ones.

• Youve run digital forensics across cloud endpoint and network evidence and reconstructed what an attacker actually did.

• Youve stood up or substantially rebuilt an incident response program rather than only operating inside someone elses.

• Youve hunted for threats proactively and found activity that existing tooling missed.

• You write incident reports and postmortems clear enough that both engineers and executives act on them.

• Bonus: Experience defending high-value targets such as AI labs financial infrastructure or critical infrastructure against nation-state threat models. Cloud-native forensics (AWS GCP). Detection engineering and SIEM or SOAR tooling. Malware analysis or reverse engineering.

We are committed to pay equity and transparency.
