Fluidstack at a glance
Builds and operates gigawatt-scale AI data centers and fully managed GPU clusters for frontier AI labs, governments, and enterprises.
Fluidstack acquires power, designs and builds data centers, and operates them, and it delivers fully managed multi-thousand-GPU clusters to AI companies. It pitches gigawatts of compute in roughly six months versus an industry norm of 18 to 24, and is the builder behind Anthropic's $50B US data center buildout.

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. If that is you, please apply!
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.
THE DATA CENTER DESIGN TEAM
Examples of key problems the team is working on
- Lead the design, development, and execution of 10s to 100s of GWs of data centers this decade.
- Drive the next generation of liquid cooling and electrical distribution systems.
- Develop and scale first-of-a-kind modular data centers.
- Influence behind-the-meter designs and planning for multi-GW campuses.
ROLE SCOPE
- Own the civil engineering workstream across a multi-site development portfolio from site screening through permitting and construction completion.
- Lead civil due diligence for greenfield and conversion sites: topography, drainage, utilities, soils, floodplain, and environmental constraints, flagging fatal flaws and cost risks during site selection.
- Develop and maintain the civil basis of design, master specs, and standard drawings, and establish grading strategies, earthwork balance, and cut/fill sequences for large campus developments.
- Structure phased delivery with early work packages (mass grading, site utilities, enablement) to accelerate the critical path.
- Lead civil permitting strategy across jurisdictions: land disturbance, NPDES/SWPPP, floodplain (CLOMR/LOMR), environmental, and utility permits.
- Manage external civil consultants from schematic through IFC and coordinate civil scope with structural, MEP, fiber, and architectural teams.
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. jobs.ashbyhq.com
- You've owned civil engineering on large-scale site development (data centers, industrial, logistics, or power infrastructure), ideally owner/developer-side.
- You've directed external civil consultants and managed design deliverable quality through IFC.
- You know grading, earthwork, stormwater, and site utility design cold, plus NPDES and floodplain (FEMA/CLOMR/LOMR) permitting.
- You've identified civil fatal flaws and quantified cost risk during site selection, not just executed design after the site was chosen.
- You've coordinated geotechnical investigations and interpreted boring programs into design actions.
- Bonus: PE license. Hyperscale or energy infrastructure development. Expansive clay, karst, or high water table conditions. MISO/utility interconnection civil coordination. AutoCAD Civil 3D and GIS.
We are committed to pay equity and transparency.
