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 HSE Team

Examples of key problems the team is working on

• Own safety on gigawatts of high-energy infrastructure, built from zero. Headcount and sites are scaling faster than institutional knowledge can keep up. The gap between a control written on paper and one actually applied in the field is where fatalities happen.

• Keep a 24/7 workforce running at full intensity, not sidelined by injury. Fatigue, shift work, and high-energy exposure compound on the people running the sites and show up as injuries or claims if no one is tracking them. The work is to catch them first.

• Keep environmental compliance ahead of the fastest build in the industry. Behind-the-meter generation spans multiple states, each with its own air permit conditions, runtime limits, and reporting deadlines, and the company adds sites faster than any manual compliance model can keep up with.

Role Scope

• Own hazardous energy control across multiple concurrent gigawatt-scale data center builds, from first temporary power through construction, Level 1 to Level 5 commissioning, and handoff to operations.

• Write, review, and approve every switching plan, LOTO procedure, energization sequence, and zero-energy verification before medium-voltage or low-voltage gear is landed, tested, or turned on.

• Run the pre-energization and energization kick-off meetings, and hold sole authority to authorize, pause, or stop any energization, isolation, or restoration across the GC, electrical contractors, commissioning agents, and the utility.

• Audit the electrical safety program in the field: JHAs, energized work permits, boundary controls, PPE, arc flash labeling, and the gap between the written control and what the crew actually does at the gear.

• Create and run the Kirk key program: collect, log, and control every Kirk key as switchgear, transformers, and generators are delivered to site, and turn the full key inventory over to operations at handoff.

• Maintain the tamper seal program on all energized and isolated equipment, and act as the only person who can authorize breaking a tamper seal.

• Manage the contract site-level Energy Marshals at every active campus: select and onboard them, set the standard they work to, audit their switching plans and field practice, and remove anyone who does not meet it.

• Build the multi-site Energy Marshal standard, including the templates, energization tracker, and training, so a new campus stands up its energization program in days rather than months.

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 performed as an Energy Marshal or Controlling Energy Marshal for a minimum of five years on data center or mission-critical construction, and have run energizations end to end on more than one site at a time.

• You hold current NFPA 70E qualified-person training and a recognized electrical safety credential (NFPA CESCP or CESW), plus OSHA 30 Construction and current First Aid/CPR/AED.

• You've personally written and approved switching orders and LOTO procedures on MV (above 1000V) and LV distribution: utility service, MV switchgear, transformers, generators, UPS, PDUs, and busway.

• You've stopped an energization when the paperwork was signed but the field didn't match it, and you can walk through the call and how you got the work restarted safely.

• You've directed other Energy Marshals or electrical safety leads across more than one site, held them to a single standard, and replaced one who fell short of it.

• You've coordinated GC, electrical subcontractor, commissioning agent, utility, and owner operations teams on a live campus where construction and energized systems share walls.

• You've run a Kirk key interlock or tamper seal program on live gear and can account for every key and seal from delivery through turnover.

• You keep the energization log, permit records, and isolation registers current enough that an auditor or incident investigation can reconstruct any switching event on any site.

• You explain arc flash boundaries, incident energy, and approach distances to an apprentice and to a VP with the same clarity.

• Bonus: Electrician licensure (journeyman or master). Utility safety leadership (CUSP). Commissioning credentials (CxA, QCxP). Arc flash and coordination study review (SKM, ETAP). Behind-the-meter generation and multi-state utility interconnection.
