Staff Incident Responder

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!

About the Role

Fluidstack operates the compute infrastructure powering frontier AI. The work running on it is among the most consequential being done today, and the adversaries interested in it are among the most sophisticated, persistent, and well-resourced anywhere. We are building Detection & Response Engineering from the ground up: engineering-led, agent-first, and built to scale across IT, OT, and physical surfaces. As the Staff Incident Responder, you are the most senior incident commander in the program. You define what material-incident response looks like at Fluidstack, set the runbook standard the rest of the IR function operates inside, and lead the room when those systems come under attack.

Preferred Qualifications

• Experience running incidents that bridge cyber, physical, and OT or ICS surfaces. • Experience at critical-infrastructure operators, data centers, or industrial environments. • Experience designing or operating agent-augmented incident response, including triage, investigation, or response automation. • Experience tuning LLM-based IR systems against measured precision and recall.

About You

• You have run material incidents at companies with sophisticated threat models, as the most senior commander on the call. • You have made disclosure-grade calls under regulatory and customer reporting clocks. • You have written runbooks that other engineers followed under pressure, and rewritten them after they did not work. • You have built operational processes from the ground up in environments where structure did not previously exist. • You read the agent-first thesis as one of the most interesting design choices in incident response today. • You have well-founded opinions on what makes a runbook actually used or an incident response process actually effective. • You move fluently between technical containment and executive, legal, or customer-facing conversations during a declared incident. • You see what is needed, scope it yourself, and run with it.
