Data Center Capacity Analyst

Fluidstack; Austin (TX); On-site; USD 120,000 - 180,000; Full time

Job summary

Fluidstack is building civilization-scale infrastructure for AI and seeks a capacity/space planning specialist to model greyspace and track capacity across multiple sites. You will own capacity models, maintain a single source of truth, and present options with trade-offs to inform decisions.

You will work with electrical, mechanical, and project teams to ensure capacity plans align with design and delivery while pushing for fast, precise execution in a high-urgency environment.

Qualifications

• Capacities to model space, electrical, mechanical budgets for data center sites.
• Able to build capacity models that reveal constraints early.
• Comfort with drawings and spreadsheets to support capacity decisions.
• Maintain a single source of truth across multiple concurrent changes.
• Present constraints with actionable options and trade-offs.

Responsibilities

• Model greyspace capacity across sites and budgets.
• Track allocation as designs evolve and catch shortages early.
• Create source-of-truth views used by design, delivery, and operations.
• Analyze trade-offs when programs compete for same space or capacity headroom.

Job description

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.

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.

Role Scope

• Model greyspace capacity across sites: the electrical, mechanical, and support space budgets behind every megawatt of whitespace.

• Track allocation against design as builds evolve, catching where greyspace runs out before power does.

• Build the source-of-truth views that design, delivery, and operations use to answer whether it fits.

• Analyze trade-offs when programs compete for the same square footage or capacity headroom.

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 done capacity or space planning for data centers, industrial plants, or utilities.

• You're comfortable in drawings and single-lines as well as spreadsheets.

• You've built capacity models that caught a real constraint early.

• You keep a source of truth current across many concurrent changes.

• You present a constraint with options attached.

• Bonus: DCIM tools. Electrical and mechanical fundamentals. SQL and BI tooling. Multi-site portfolios.

We are committed to pay equity and transparency.
