AI Cluster Architect

Job Summary

To create and refine large-scale GPU cluster architectures within strict power and infrastructure limits, the full-time AI Cluster Architect will focus on power-aware design, optimizing GPU density while managing compute services, storage, and networking in a remote environment.

Key Responsibilities

• Architect large-scale GPU clusters within fixed site power budgets to maximize GPU density while considering compute, storage, and networking needs
• Model and validate power consumption across the full cluster bill of materials, ensuring compliance with facility limits
• Evaluate tradeoffs across various fabric networking architectures and document design choices and operational considerations

Required Qualifications

• 7+ years of experience designing or building large-scale HPC, AI, or hyperscale GPU clusters
• Expert understanding of GPU and accelerator system design, including node topology and PCIe/NVLink/NVSwitch/ROCm
• Strong familiarity with InfiniBand, RoCE, and SpectrumX networking, including multi-tier and large-radix switch design
• Demonstrated experience modeling power draw and thermal characteristics of various server components
• Proven ability to gather and analyze vendor SKU-level specifications for scalable cluster architectures
