Rack Systems Architect, Technical Lead

About the role

The Rack Systems Team at Fluidstack is responsible for owning the rack as a product for 150kW-class liquid-cooled deployments. This includes architecture, power budget, cooling, interconnect topology, structure, and serviceability, with tradeoffs made explicitly and defended on the record.

Responsibilities

• Own the rack as a product for 150kW-class liquid-cooled deployments: architecture, power budget, cooling, interconnect topology, structure, and serviceability, with tradeoffs made explicitly and defended on the record.
• Write and hold the interface control documents between rack and facility, precise enough that power, liquid, and network teams can each move independently without breaking the boundary.
• Lead the rack EE, ME, and thermal engineers, owning the architecture they execute and the technical calls that unblock them.
• Align the rack roadmap with accelerator vendors and Fluidstack's facility architecture, so each rack generation lands in a facility built to receive it.

Requirements

• 10+ years in system architecture of rack-scale compute at a hyperscaler, NVIDIA-ecosystem ODM, or AI systems company.
• You've owned a rack as a product end to end: power budget, cooling architecture, interconnect topology, weight, transport, and serviceability.
• You've shipped dense liquid-cooled rack-scale products, NVL-class or equivalent.
• You've led the EE, ME, and thermal engineers who executed your architecture, not just advised them.
• You've traded real things away on a shipping rack and taken the pushback that came with it.
• You write interface control documents that let both sides of a boundary move independently, and you've seen what happens when they don't.
• You hold a defensible view on copper versus optics for scale-up interconnect at 200G+ per lane, and you can argue where the crossover sits.

Qualifications

• Bonus: NVL-class rack programs, transport and seismic qualification, facility-side liquid cooling fluency, or direct engagement with accelerator vendor roadmaps.

Skills

• System architecture of rack-scale compute.
• Experience with dense liquid-cooled rack-scale products.
• Leadership of EE, ME, and thermal engineers.
• Interface control document writing.
• Experience with copper versus optics for scale-up interconnect.
