Fluidstack is building civilization-scale AI compute infrastructure, acquiring power, designing and operating data centers at unprecedented speed and scale. The Manufacturing Engineering team is responsible for taking product lines from concept to production, designing data center modules, switchgear, switchboards, busway, skids, E-Houses, and cooling systems that power Fluidstack's 10+ GW annual capacity.
As Chief Engineer for MV Switchgear, you will own the clean-sheet design of Fluidstack's wholly-owned metal-clad medium-voltage switchgear platform, built around a purchased, type-tested vacuum breaker element. You will deliver a production-released, fully type-tested lineup while running IEEE C37.20.2 and C37.09 test campaigns in parallel. This is a leadership role where you will lead a dedicated team of engineers through design, testing, and compliance efforts.
Key responsibilities include:
- Own end-to-end design authority from one-line diagrams through type testing to factory acceptance
- Run the type-test campaign at high-power laboratories, covering short-circuit, internal arc, BIL, and temperature rise testing
- Own every redesign loop following test results
- Define the platform's ratings ladder, protection and IED integration, and racking and interlock architecture to support MV distribution across 10 GW of buildings annually
- Lead product team from first concept to production release, holding design freeze against late-arriving changes
- Challenge industry standards and focus on speed and safety through first-principles reasoning
Fluidstack operates with full autonomy, insane urgency, first-principles reasoning, and a focus on building something that matters. The role requires ownership end-to-end, taking on scope without permission, and operating at high intensity.
REQUIREMENTS:
- Designed metal-clad MV switchgear and/or GIS switchgear at an OEM as the accountable engineer
- Taken a switchgear design through a full type-test campaign at a high-power lab and led redesign after failed internal arc or short-circuit testing
- Made insulation coordination, bus bracing, and creepage and clearance decisions
- Integrated third-party breaker elements or operating mechanisms into an enclosure and secondary design owned end-to-end
- Led a product team from first concept to production release and held design freeze against late-arriving change requests
