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 Civil, Structural and Architectural R&D Team The CSA R&D team designs the template buildings, foundations, and modular structures that Fluidstack builds again and again for gigawatt-scale AI data centers. We engineer the design once, prove it, and hand delivery teams a package they can build without reinventing it. Examples of key problems the team is working on

  • Design a repeatable building and foundation system that survives fabrication, transport, and site conditions across very different geographies.
  • Bring structural engineering in-house so design decisions close in days, not in weeks of waiting on an outside engineer of record.
  • Resolve the collisions between structure, equipment, and MEP: load paths, penetrations, attachment points, and tolerances in a tight envelope.
  • Turn factory and field lessons into engineered fixes in the next design revision.

Role Scope

  • Own the structural calculations. Run gravity, lateral, foundation, lifting, and transport analyses for template buildings, equipment supports, skids, and modular structures, and stand behind the numbers.
  • Produce the detailed designs. Take structural systems from concept through fabrication-ready drawings, connection details, and specifications without handing the work to a third party.
  • Make the design repeatable. Build the standard details, load tables, and design rules that let the same structure be built at many sites with minimal site-specific engineering.
  • Integrate across disciplines. Resolve where structure meets architecture, mechanical, electrical, and fire protection so the package builds clean.
  • Run structural support for the factory and the field. Answer RFIs, review shop drawings and submittals, and engineer fixes into the next revision.
  • Hand off to delivery. Package the design so site teams, fabricators, and local engineers of record can execute it with minimal rework.

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 have 7+ years of structural engineering on industrial, mission-critical, or data center buildings, with steel, concrete, and foundation design in your own hands.
  • You perform your own calculations and produce your own detailed designs. You do not need an outside engineer to close a design.
  • You know the codes cold: IBC, ASCE 7, AISC 360, ACI 318, and how to apply them across seismic, wind, and snow regions.
  • You work in structural analysis and drafting tools daily (RISA, SAP2000, ETABS, RAM, Revit, or equivalent) and your drawings build without a stream of fabricator calls.
  • You have designed pre-engineered metal buildings, equipment foundations, or modular and transported structures, and you treat lifting and transport loads as first-class constraints.
  • You work across disciplines instead of throwing problems over walls, and you iterate fast without losing configuration control.
  • Bonus: PE license (SE a plus). Experience as engineer of record on hyperscale data center or industrial projects. DfMA and modular construction depth.
