Chief Engineer, MV Switchgear

Fluidstack; Northern (KY); Hybrid; USD 140,000 - 220,000; Full time

Job summary

Fluidstack is seeking a senior electrical engineer to own the design of metal-clad MV switchgear and drive performance from concept to production. You will lead a team through type-testing campaigns at high-power labs, integrate third-party breakers, and define protection architectures for multi-GW deployments.

We value first-principles reasoning, rapid execution, and building infrastructure that accelerates AI readiness.

Qualifications

• Designed metal-clad MV switchgear at an OEM as the accountable engineer.
• Led a switchgear design through a full type-test campaign at a high-power lab and directed redesign after failures.
• Made insulation coordination, bus bracing, creepage and clearance decisions.
• Integrated third-party breaker elements into an enclosure and owned secondary design end to end.
• Led a product team from concept to production release and managed design freeze amid late-change requests.

Responsibilities

• Own the clean-sheet design of Fluidstack's metal-clad MV switchgear platform.
• Deliver a production-released, fully type-tested lineup with parallel test campaigns.
• Lead a dedicated team of engineers for design, testing and compliance.
• Run high-power laboratory type-tests including short-circuit and temperature rise; manage redesign loops.
• Define platform ratings ladder, protection and IED integration, and racking architecture for large-scale deployments.

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.

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 Manufacturing Engineering Team

Examples of key problems the team is working on

• Take product lines from clean sheet to production. This is an opportunity to reason from first principles. Challenge every industry standard and focus on Speed and Safety.

• Build Data Center products behind 10s of GW a year. Design and productize Data Center modules, switchgear, switchboards, busway, skids, E-Houses, and cooling systems that every Fluidstack building runs.

• Own the designs, IP, and test campaigns. Full in-house design authority on platforms Fluidstack owns outright, from the first one-line through type testing to factory acceptance.
  

Role Scope

• Own the clean-sheet design of Fluidstack's wholly-owned metal-clad MV switchgear platform, built around a purchased, type-tested vacuum breaker element.

• Deliver a production-released, fully type-tested lineup running design and the IEEE C37.20.2 and C37.09 test campaigns in parallel.

• Lead a dedicated team of engineers to develop the design, testing and compliance effort.

• Run the type-test campaign at high-power laboratories, covering short-circuit, internal arc, BIL, and temperature rise, and own every redesign loop as needed.

• Define the platform's ratings ladder, protection and IED integration, and racking and interlock architecture so one design covers MV distribution across 10s of GW of buildings a year.

What We're Looking For

• You've designed metal-clad MV switchgear and/or GIS switchgear at an OEM as the accountable engineer.

• You've taken a switchgear design through a full type-test campaign at a high-power lab and led the redesign after a failed internal arc or short-circuit shot.

• You've made the insulation coordination, bus bracing, and creepage and clearance decisions.

• You've integrated third-party breaker elements or operating mechanisms into an enclosure and secondary design you owned end to end.

• You've led a product team from first concept to production release and held the design freeze against late-arriving change requests.

We are committed to pay equity and transparency.
