Rack Systems Architect & Tech Lead — 150kW Liquid-Cooled

fluidstack; New York (NY); On-site; USD 180,000 - 260,000; Full time

Job summary

Fluidstack is seeking a senior Rack Systems Architect in the United States to own the rack as a product for 150kW-class deployments. You will define power budgets, cooling architectures, and interconnect strategies while leading EE/ME/thermal teams to high-integrity designs.

You will drive interface control documents and design reviews to prevent field faults, and align roadmaps with accelerator vendors and Fluidstack facilities for scalable deployments.

Qualifications

• 10+ years in system architecture of rack-scale compute at a hyperscaler or AI systems company.
• Own a rack as a product end to end: power budget, cooling, interconnect topology, weight, serviceability.
• Shipped dense liquid-cooled rack-scale products (NVL-class or equivalent).
• Led EE, ME, and thermal engineers who executed your architecture.
• Wrote interface control documents enabling independent movement across a boundary.

Responsibilities

• Own the rack as a product for 150kW-class deployments: architecture, power budget, cooling, interconnect topology, structure, and serviceability.
• Write and hold the interface control documents between rack and facility, precise enough that power, liquid, and network teams can move independently.
• Lead the rack EE, ME, thermal, and integration engineers, owning the architecture they execute.
• Run design reviews where a 7-person team catches what a 70-person team would, and faults die in review.
• Align the rack roadmap with accelerator vendors and Fluidstack's facility architecture.
