Principal Incident Responder

How We Operate

• Extreme ownership.
• Full autonomy.
• Velocity.
• First principles.
• Love of the game.

Role Scope

• Serve as the most senior incident commander in the program, running material incidents across detection, response, physical security, data center operations, legal, communications, and customers.
• Build the IR program from the ground up: runbook standards, severity definitions, materiality methodology, evidence contracts, and post-incident review cadence.
• Define the agent-human contract for response: escalation criteria, evidence packages required from agents, and human-verdict feedback into agent quality.
• Design and operate the senior-IR on-call rotation (ack SLAs, escalation chain, fan-out), and stay an active senior IC inside it.
• Turn incident trends into systemic fixes, drive cross-functional remediation to completion, and define and report the IR program's KPIs to leadership.
• Set the tabletop and exercise cadence, and carry the external face of IR for regulatory and customer disclosure obligations and audits.

What We're Looking For

• You've run material incidents as the most senior commander on the call, at companies with sophisticated threat models.
• You've made disclosure-grade calls under regulatory and customer reporting clocks.
• You've written runbooks other engineers followed under pressure, and rewritten them when they didn't work.
• You've built operational processes from nothing where no structure existed, and you find the agent-first thesis one of the most interesting design choices in IR today.
• You move fluently between technical containment and executive, legal, and customer conversations during a declared incident.
• Bonus: Incidents bridging cyber, physical, and OT/ICS. Critical-infrastructure, data center, or industrial environments. Agent-augmented IR, including tuning LLM-based systems against measured precision and recall.

Salary & Benefits

• Competitive total compensation package (salary + equity).
• Retirement or pension plan, in line with local norms.
• Health, dental, and vision insurance.
• Generous PTO policy, in line with local norms.

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!
