AI Cluster Architect

Role description

Role Overview

Create and refine large-scale GPU cluster architectures within strict power and infrastructure limits. Focuses heavily on power-aware design, understanding how different GPU SKUs, NICs, switches, and fabrics interact at scale.

What You Will Do

Architect large-scale GPU clusters, model and validate power consumption, evaluate tradeoffs across multiple fabric networking architectures, and determine network scale limits.

Why It Might Be a Fit

Must have deep experience navigating heterogeneous environments, multiple generations of hardware, and end user requirements, with strong documentation, communication, and cross-functional collaboration skills.

Requirements

• 7+ years designing or building large-scale HPC, AI, or hyperscale GPU clusters
• Expert understanding of GPU and accelerator system design
• Strong familiarity with InfiniBand, RoCE, and SpectrumX networking
• Demonstrated experience modeling power draw and thermal characteristics of servers, GPUs, NICs, switches, optics, and storage systems
• Ability to design networks that maintain full non-blocking performance or intentionally introduce over/under-subscription
• Proven ability to gather and analyze vendor SKU-level specifications
• Experience balancing customer-driven requirements for compute, storage, and service density
• Strong documentation, communication, and cross-functional collaboration skills
