Full Job Description
The Data Center Operations Team
Examples of key problems the team is working on
Operate at the scale of a nation, not a building. Accelerating toward 10s to 100s of GWs by the end of the decade, more than the entire electricity consumption of many countries. You won't just run a data center; you'll run infrastructure the size of a G7.
Fly the plane while it's being built. Running flawless operations inside a live construction zone, adapting in real time and turning the pace of build-out into our advantage. You will redefine operational excellence.
Write the playbook, don't inherit it. Most operators step into someone else's system. Here you build one, leaving your fingerprints on how the whole company runs. As we scale 100x, you'll set the standards, shape the operating model, and grow the team by the thousands.
Role Scope
Serve as the most senior technical authority for operational mechanical and cooling infrastructure across the hyperscale AI data center fleet.
Lead site assessments and operational audits, and drive team technical readiness ahead of site activation.
Review designs and specifications from an operational lens, and feed operational learnings back into design and manufacturing as the build model becomes productized.
Be the senior voice on chillers, cooling towers, CDUs, and the liquid-cooling architectures AI infrastructure depends on.
Own mechanical operational readiness and the commissioning-to-operations handover for new sites.
Author and approve high-risk mechanical MOPs, EOPs, and AOPs, and lead root cause analysis on significant cooling events.
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 spent a career on critical mechanical systems and you treat thermal precision as non-negotiable for AI workloads.
You command chilled water, chillers, cooling towers, CRAH/CRAC, pumps, CDUs, and direct liquid cooling in live environments.
You've authored and executed high-risk mechanical MOPs and led root cause analysis on significant cooling events.
You assess operational readiness at any site, audit the posture, and raise the standard.
You teach and build the mechanical readiness of teams ahead of activation.
Bonus: Hyperscale or large colocation at hundreds of MW. Direct liquid cooling and CDU operations. ASHRAE TC 9.9. Chilled water plant optimization. Uptime Institute.
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.
Total compensation may also include equity in the form of restricted stock units.
We are committed to pay equity and transparency.
