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!
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 Modular team is building factory-produced modular data centers, taking them from released drawings to rate production on our Phoenix manufacturing line.
Examples of key problems the team is working on:
Bring first-of-a-kind modular data center designs from engineering release to repeatable rate production on the factory line
Engineer power distribution, grounding, and controls integration that builds clean at the station and holds up in the field
Run first-article inspections and electrical checkout so the first unit off the line and the hundredth meet the same bar
Close the loop between the floor and the drawing set, so every issue caught at a station is engineered out of the next revision
Own the electrical systems of the modular product on the line: power distribution, grounding, and controls integration, from released drawings through rate production
Live on the Phoenix manufacturing floor: walk the line daily, catch wiring and termination issues at the station where they happen, and disposition them on the spot
Answer electrical RFIs same-day from the floor, then engineer the fix into the next revision so the same question never comes up twice
Run first-article reviews and electrical checkout in person as units come down the line, with findings documented rigorously enough to drive design and process change
Close the loop to design: feed what the line learns back into one-lines, panel schedules, and the BOM, keeping the drawing set the single source of truth
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 engineered electrical systems hands-on for complex physical products, modular construction, or critical facilities
You've worked on a shop floor or production line, and dispositioning a nonconformance in the moment is familiar work, not an escalation
You've supported production launches of your own designs and stayed with them until the line ran clean
Your drawings build clean: fabricators and electricians rarely call, and when they do, you fix the drawing, not just the unit
You iterate fast without losing configuration control: every floor fix lands in the released drawing set, not in tribal knowledge
You're equally credible in a design review and at the station with a multimeter, and the techs on the line trust your dispositions
Bonus: PE license, working knowledge of NEC and UL 508A panel standards, data center power distribution experience, panel checkout and QC background, or strong DFM instincts
We are committed to pay equity and transparency.
