## Description

We are seeking a GPU Cluster Architect to drive the design of our next-generation AI infrastructure. In this high-impact, hands-on role, you will make end-to-end architectural decisions across compute, networking, and storage , ensuring our platforms can meet the massive scale, performance, and reliability requirements of modern AI workloads.

This is a high-impact, hands-on architecture role where you’ll define how tens of thousands of GPUs are interconnected, cooled down, powered, and optimized across multiple data center sites.

Your responsibilities will include:

- Cluster Design: Architect scalable GPU cluster topologies including compute nodes, interconnect (InfiniBand, Ethernet), storage, and control planes.

- Performance Modeling: Analyze AI/ML workloads (e.g. LLM training, inference) to inform design tradeoffs across latency, bandwidth, and GPU density.

- Network Architecture: Align with network architect relevant design and validate low-latency, high-throughput interconnects (e.g., InfiniBand HDR/NDR, RoCEv2) at POD and DC scale.

- Storage Integration: Work with storage teams to optimize performance for training datasets, checkpointing, and others.

- Reliability & Monitoring: Understand and analyze signal from monitoring systems to detect flows in design.

- Collaboration: Partner with site reliability, networking, storage, and DC engineering teams to operationalize and scale your architecture.

We expect you to have:

- 5+ years of experience designing clusters.

- Deep understanding of modern GPU architecture (NVIDIA, AMD, etc.).

- Experience with HPC interconnects (InfiniBand & RoCE).

- Solid background in systems architecture, networking, and hardware reliability.

- Experience in scripting for automation and telemetry pipelines (Python, Go, etc.)

Benefits & Perks:

- Competitive compensation

- Career growth and learning opportunities

- Flexibility and ownership

- Collaborative and innovative culture

- Opportunity to work on impactful AI projects

- International environment and talented teams
