Job summary

Fluidstack is building civilization-scale infrastructure for AI. The Product Engineering, Electrical Equipment Team seeks a senior design leader to own the LV/MV switchgear, BBU, and busway lineup, drive the certification strategy, and coordinate EE, ME, controls and drafting.

This is a hands-on, leadership-heavy role focused on scalable, safe, certificated gear for data-center projects. You will shape ratings philosophy, decide make-vs-buy, and guide a 9-person gear team.

Qualifications

• 12+ years in switchgear and electrical equipment design.
• Experience leading design teams at an OEM (Powell, IEM, Eaton, ABB or equivalent).
• Experience with UL 891/1558 or IEC 61439 listings and witness testing at labs.
• Experience in handling short-circuit test failures and retests.
• Ownership of product architecture across LV/MV lineup including BBU integration.
• Ability to structure a 9-person gear team and staffing decisions.
• Defending ratings philosophy against test labs and cost targets.

Responsibilities

• Own product architecture across LV/MV switchgear, BBU, and busway lineup.
• Lead end-to-end certification strategy: NRTL relationships, test campaigns, lab bookings and budgets.
• Guide the gear design team across EE, ME, controls, and drafting.
• Set the ratings philosophy for short-circuit, withstand and temperature-rise design standards.
• Make make-vs-buy recommendations per product category backed by cost, schedule and risk.

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.

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.

Product Engineering, Electrical Equipment Team

Examples Of Key Problems The Team Is Working On

• Design an LV/MV switchgear, BBU, and busway lineup purpose-built for AI data centers instead of adapting legacy utility gear.
• Get first-of-a-kind gear through NRTL certification on schedules where a failed test shot costs months, not weeks.
• Decide product by product what we design in-house, what we co-develop with OEMs, and what we simply buy.
• Converge the lineup on the minimum set of frame sizes and bus ratings that covers the overwhelming majority of site demand.

Role Scope

• Own product architecture across the LV/MV switchgear, BBU, and busway lineup, including the frame-size and bus-rating matrix that covers 90% of demand with the fewest SKUs.
• Run the certification strategy end to end: NRTL relationships, test campaign sequencing, lab bookings, and budgets that account for the real cost of a failed shot.
• Lead the gear design team across EE, ME, controls, and drafting, with team structure and staffing decisions that hold up as the lineup grows.
• Set the ratings philosophy for the lineup: short-circuit, withstand, and temperature-rise design standards rigorous enough to pass witness testing on the first campaign.
• Make the make-vs-buy recommendation per product category, including the call that we shouldn't build a category at all, backed by cost, schedule, and certification-risk math.

What We're Looking For

• 12+ years in switchgear and electrical equipment design, with time leading design teams at an OEM such as Powell, IEM, Eaton, ABB, or equivalent.
• You've personally taken gear through UL 891/1558 or IEC 61439 listing, including witness testing at KEMA or PowerTech-class labs.
• You've lived through a short-circuit test failure, driven it to root cause, and led the redesign that passed the retest.
• You've owned product architecture across an LV/MV lineup, including BBU integration and the certification path each integration option implies.
• You know how to structure a 9-person gear team: which seats can double up, which can't, and where the first hire goes when the lineup expands.
• You can defend a ratings philosophy, short-circuit, withstand, and temperature-rise, against both a test lab and a cost target.
• Bonus: BBU or energy storage integration into gear, busway product experience, arc-resistant designs, or deep NRTL relationships.

We are committed to pay equity and transparency.
