About Fluidstack

Technology is the most important tool humans have found for improving the human condition, but it is not a default good. It is a lever for ideology.

Today the most powerful technology in history is being built: machines that solve problems better than humans can. The most important mission of our generation is to imbue AI with democratic values: error-correcting institutions, freedom of speech, individual liberties. AI trains and runs on massive compute clusters. Whichever ideology builds the infrastructure the fastest is the ideology that will endure. Democracy is delicate and won't survive this technology by default.

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.

About the Role

As Cost Lead, you will own cost management across our data center portfolio — from early-stage budgeting and estimating through construction and final account. You'll set up process where it doesn't exist, build benchmarks from scratch, and serve as the Cost Lead of our delivery program. You'll work closely with project managers, A/E design teams, GCs, and other Leads to keep every project on-budget and every decision grounded in credible numbers.

Own cost planning across all project phases — from concept and pre-design through construction documents and GMP negotiation
Develop detailed estimates for civil, structural, MEP, HV/LV power, cooling, fuel systems, and shell construction
Maintain real-time cost forecasts across all active projects; track actuals vs. budget and surface variances early
Own change order review: assess scope validity, commercial accuracy, and contract entitlement before recommending approval
Prepare executive-level cost reports across the portfolio — clear, scannable, exception-based
Manage contingency tracking and cost risk registers across project phases
Lead value engineering exercises with design and construction teams to optimise cost without compromising scope or schedule
Support GC and subcontractor procurement: bid leveling, scope gap analysis, and contract negotiation input
Advise on contract structure and commercial risk allocation across delivery models
Build the cost management function from the ground up: tools, templates, workflows, and reporting cadence
Establish and maintain a unit cost benchmark database covering key DC cost categories — from $/MW to equipment and trade breakdowns
Contribute to precon planning on new sites, including order-of-magnitude estimates to support site selection and investment decisions

Qualifications:

Experience with cost management, quantity surveying, or construction estimating
Meaningful hands-on experience on data center or mission-critical construction — hyperscale, colo, or large-scale build-to-suit
Owner-side experience strongly preferred; GC or QS consulting backgrounds considered if DC domain knowledge is deep
Deep understanding of the DC cost stack: civil, structural, MEP, HV/LV power, cooling (CRAC/CRAH, DLC, immersion), emergency power, and IT fit-out
Understands how design decisions — power density, redundancy tier, cooling strategy — translate directly to capital cost
Comfortable benchmarking at $/MW, $/SF, and $/kW; knows what drives variation between projects
Strong change order discipline: can assess pricing validity, identify scope gaps, and document entitlement
Familiar with GMP, lump sum, and cost-plus contract structures
Proficient with cost management tooling (Procore, Sage, or equivalent); can build process from scratch
Degree in construction management, quantity surveying, engineering, or related field
Builder mindset — comfortable setting up function and process where little exists, and operating with urgency in a fast-moving program
