Own the rack as a product for 150kW-class, liquid-cooled AI deployments—covering architecture, power budget, cooling, interconnect topology, structure, and serviceability. Create and maintain interface control documents between rack and facility so power, liquid, and network teams evolve independently. Lead EE/ME/thermal/integration engineers, run high-rigor design reviews, and align the rack roadmap with accelerator vendors and facility architecture.

Key Responsibilities

  • •Own the rack as a product for 150kW-class, liquid-cooled deployments, including architecture, power budget, cooling, interconnect topology, structure, and serviceability.
  • •Write and hold interface control documents between rack and facility so power, liquid, and network can evolve independently.
  • •Lead the rack EE, ME, thermal, and integration engineers, owning the architecture and technical decisions that unblock execution.
  • •Run design reviews with high rigor so faults are caught before integration; align stakeholders to the rack roadmap.
  • •Coordinate the rack roadmap with accelerator vendors and facility architecture so each rack generation lands in a facility designed to receive it.

Key Requirements

  • •10+ years in system architecture of rack-scale compute at a hyperscaler, NVIDIA-ecosystem ODM, or AI systems company.
  • •Own rack end-to-end: power budget, cooling architecture, interconnect topology, weight, transport, and serviceability.
  • •Ship dense liquid-cooled rack-scale products (NVL-class or equivalent).
  • •Lead EE, ME, and thermal engineers who executed your architecture, not just advised them.
  • •Write interface control documents that enable independent boundary evolution, and defend tradeoffs (e.g., copper vs optics for 200G+ per lane).
