Sourcing Manager, Compute & Storage
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
Extreme ownership. Full autonomy. Own things end to end often taking on scope outside your core role without being asked to get things done.
Velocity. We drive everything forward as fast as possible.
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.
The Supply Chain Team
Examples of key problems the team is working on
Supply tens of gigawatts of compute, the largest build out of compute in history. Qualify and dual-source across every critical equipment category, with lead-time and capacity thresholds tied directly to the forward build pipeline.
Make supply chain the reason we build faster than anyone. Our modular build redefines speed in this industry, and it lives or dies on supply chain. Keep procurement permanently off the critical path so schedule compression stays our advantage, not our constraint.
Build the most accurate supply chain prediction modelling that exists. Use the frontier of AI to forecast lead times, demand, and disruption with a precision the industry has never had, and turn that foresight into a structural edge.
Role Scope
Own the consumables category: coolant, filters, spares kits, PPE, and everything sites burn through daily.
Set stocking strategies per site so consumables never idle a crew, without tying up capital in dead stock.
Negotiate national and regional agreements that give every new site pricing and supply from day one.
Build the replenishment system that reorders on consumption data rather than someone noticing an empty shelf.
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 managed high-SKU-count procurement (MRO, consumables, spares) across multiple sites.
You've set min/max stocking levels from usage data and defended them against both stockouts and write-offs.
You standardize SKUs across sites so purchasing power consolidates.
You automate reordering rather than running it on memory.
Bonus: Data center or industrial MRO. Coolant and liquid cooling consumables. VMI programs. Punchout catalog systems.
We are committed to pay equity and transparency.

The Security Team
Examples of key problems the team is working on
You're securing the frontier of AI. The model weights training on our infrastructure are the most valuable and most targeted artifacts in technology, and we're standing up the compute to hold them faster than anyone ever has. A breach isn't a leak, it's the frontier walking out the door.
Build the entire security program from scratch. Most leaders inherit someone else's system and spend a career patching it. Here you own it end to end, bare metal to boardroom, as we scale across continents.
Your threat surface is measured in gigawatts. The customers running on our infrastructure are building the most consequential technology in human history, and being responsible for the physical and logical security of that work makes everything else feel small.
Role Scope
Secure the corporate environment end to end: identity, endpoints, SaaS, and email for a workforce growing 10x.
Build detection and response for the corp attack surface, from phishing to token theft to insider risk.
Engineer zero-trust access: SSO, device trust, and least-privilege provisioning that scale with hiring instead of against it.
Automate the controls so security runs as code and policy, not tickets and exceptions.
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 secured a fast-growing company's corp stack hands-on: IdP, MDM, email, SaaS.
You've built detections that caught real attacks, and tuned out the noise that buries teams.
You treat identity as the perimeter and have implemented that in practice.
You automate anything you do twice, in code, not runbooks.
You've responded to live incidents and made the containment call under pressure.
Bonus: Okta or equivalent at depth. SIEM and SOAR engineering. macOS and Windows fleet security. Insider-risk programs.
We are committed to pay equity and transparency.

Role Scope
Own the fiber and optics category: transceivers, fiber cabling, and connectivity components at hundreds of thousands of terminations per building.
Negotiate volume agreements on optics where unit price times quantity makes small percentages worth millions.
Dual-source transceiver types and manage interop qualification so second sources are real, not theoretical.
Forecast optics demand from network designs and keep supply ahead of installation crews.
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 sourced optics, fiber, or connectivity components at high volume.
You understand optics well enough (form factors, reaches, compatibility) to catch a spec mismatch before it ships.
You've qualified second-source components and managed the engineering skepticism that comes with it.
You track consumption against forecast weekly and correct early.
Bonus: 800G/1.6T optics markets. Cable assembly manufacturing. Interop testing programs. Commodity price hedging.

Qualify fabricators on quality and capacity, and manage the load balancing across them weekly.
What We're Looking For

You manage commodity exposure with indexing or hedging rather than hoping.
Bonus: AISC-certified fabrication networks. Modular construction. Weld quality programs. Logistics for oversize loads.

The Modular Team
Examples of key problems the team is working on
Design the module that makes 6-month data centers possible. Fluidstack builds data centers in months, not years, and that speed lives in the modular product: a data center engineered as a manufactured unit, not a construction project.
Take designs from concept to the manufacturing line in weeks. Concept, released drawings, first article, and rate production on a compressed schedule, with the factory building from your work the same month you release it.
Engineer for the thousandth unit, not the first. On the way to 10 GW, every drawing, tolerance, and BOM decision has to survive rate manufacturing, so repeatability is designed in from the start.
Role Scope
Engineer the mechanical systems of the modular product: cooling, piping, and airflow from concept to released drawings.
Own the liquid cooling loops, pumps, and heat rejection design the modular product's density depends on.
Solve the integration problems where mechanical meets structure and electrical: routing, interfaces, and tolerances where the disciplines collide.
Support the factory and field: mechanical RFIs answered same-day, fixes engineered into the next revision.
Prototype and validate: mockups, fit checks, and first-article reviews you attend in person.
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, .
You've engineered mechanical systems for complex physical products or modular construction hands-on.
Your drawings build clean: fabricators rarely call, and when they do you fix the drawing.
You work across disciplines instead of throwing problems over walls.
You've supported production launches of your own designs.
You iterate fast without losing configuration control.
Bonus: Liquid cooling depth. Sheet metal and piping design. 3D CAD mastery (SolidWorks, Inventor, Revit). DFM instincts.
We are committed to pay equity and transparency.

The Fluidstack Labs Team
Examples of key problems the team is working on
Qualify the hardware the frontier runs on before it runs anywhere else. First samples of next-generation accelerators, switches, storage, and liquid cooling land here, and leave as production-ready platforms with runbooks the whole fleet inherits.
Compress silicon-to-production to weeks. The lab closes the gap between vendor sample and customer-ready gigawatt infrastructure, and every week cut here pulls the entire 10 GW deployment curve forward.
Run the lab like a production site. Provisioning, telemetry, demand management, and liquid cooling mirror production architecture exactly, so a qualification pass in the lab is a deployment guarantee in the field.
Prove the power envelope nobody else will touch. Dynamic demand management lets AI compute deploy beyond nominal electrical capacity, and the lab validates the full detection-to-shutdown response chain that makes it safe.
Role Scope
Bring up first-sample accelerator platforms (NVIDIA, AMD, custom accelerators) end to end: rack integration, liquid cooling commissioning, firmware baseline establishment, network connectivity, and software stack validation at rack densities up to and beyond 120 kW.
Validate network platforms across Broadcom Tomahawk, Broadcom Jericho, and NVIDIA Spectrum silicon, driving Keysight Ixia traffic generation for RFC 2544/2889 benchmarking, line-rate stress, and protocol correctness.
Verify the optical layer with EXFO test equipment, covering BER characterization and power budget analysis across the link inventory a qualification depends on.
Qualify CDUs and liquid cooling across nVent, CoolIT, and Vertiv platforms: commissioning procedures, BMS telemetry integration, leak detection validation, coolant chemistry verification, and the operational runbooks that fall out of each pass.
Exercise the full power oversubscription response chain: graceful and forced shutdown paths, power-cap and p-state levers via BMC, ATS transfer scenarios, breaker-trip detection, rPDU commissioning with outlet-level telemetry, and repeatable power-virus stress harnesses against accelerator hardware.
Co-develop qualification matrices with hardware partners, evaluate converged local-NVMe storage platforms (Weka, Hammerspace, VAST Data), and turn results into runbooks production teams inherit.
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, .
You've personally brought up servers, accelerators, or switches from first power-on: racking, cabling, firmware, first boot, and everything that goes wrong in between.
You script your test harnesses and automation rather than clicking through runs, so your results are repeatable and your throughput compounds.
You're deep in Linux and manage hardware at the BMC level: IPMI, Redfish, sensor telemetry, and power and boot control from the command line.
You document methodically, producing test reports and runbooks that someone else can execute without you in the room.
You've worked hands-on with liquid-cooled, high-power hardware and treat its safety procedures as part of the craft.
You debug across hardware, firmware, and software layers yourself, without waiting for someone else to isolate the fault.
Bonus: RDMA/RoCEv2 fabrics. Optics testing depth. Kubernetes-based provisioning stacks. Power and electrical instrumentation experience.
We are committed to pay equity and transparency.

Develop vendor packages: CDUs, pumps, and dry coolers specified, evaluated, and integrated.
Support prototypes and first builds: test data reconciled against design.
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 designed mechanical or HVAC systems for data centers or industrial plants.
Your hydraulic and thermal calcs are yours, not the vendor's.
You've specified and integrated major cooling equipment.
You've validated designs against commissioning or test data.
You draw clean P&IDs and mean them.
Bonus: Liquid and direct-to-chip cooling. Revit or plant CAD. ASHRAE datacom depth. Field commissioning exposure.
We are committed to pay equity and transparency.
