Job description

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.

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.

Role Scope

• Engineer substation designs for campus interconnection: HV yards and MV distribution substations in the reference design.

• Own the physical and electrical design: layouts, bus configurations, and equipment specs to utility standards.

• Interface with utilities and consultants: requirements translated into designs that pass review the first time.

• Standardize the substation: one design stamped across sites instead of bespoke yards.

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 HV substations: physical, one-line, and protection interfaces.

• You've taken substation packages through utility review.

• You specify transformers, breakers, and switchgear at transmission class.

• You've supported substation construction and energization.

• You productize designs rather than redrawing them.

• Bonus: 138kV-plus experience. Grounding studies (IEEE 80). GIS substations. Interconnection processes.

We are committed to pay equity and transparency.
