Geotechnical Engineer

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 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 geotechnical workstream across a multi-site, multi-state development portfolio, from early site screening through foundation design and construction support. - Scope and direct subsurface investigation programs: write geotechnical RFPs, manage boring and CPT campaigns and lab testing, and drive external geotechnical consultants from scope through final report. - Interpret subsurface data into design parameters and assign foundation systems, working directly with Structural on bearing capacity, settlement, expansive and collapsible soils, liquefaction, seismic site class, shallow versus deep foundations, and ground improvement (rigid inclusions, piles, surcharge or preload). - Set site earthwork and grading strategy with Civil: cut and fill balance, deep-fill and differential-settlement risk to pads, MV duct banks, substations, and roads, and the call between regrade, preload, and ground improvement. - Run geotechnical fatal-flaw screening during site selection and due diligence, catching karst, mine subsidence, abandoned oil and gas wells, uncontrolled fill, high groundwater, and expansive clay before they reach signing or schedule. - Coordinate with Environmental on groundwater, contamination, and Phase II findings that drive subsurface and foundation decisions, and manage geotechnical deliverables to protect IFC and construction dates. 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 https://jobs.ashbyhq.com/fluidstack/05c2e69c-42f9-4fcb-9cf0-a467aaf98f1c. - You've owned geotechnical engineering on large-scale site development, scoping boring programs and turning subsurface data into foundation design parameters. - You've made the foundation and ground-improvement call on difficult sites: deep fill, expansive clay, high groundwater, liquefaction, choosing among shallow foundations, piles, rigid inclusions, and surcharge. - You've directed external geotechnical consultants and labs from RFP through final report, and caught errors before they reached design or construction. - You've screened sites for geot…
