Network Architect

Cerebras Systems builds the world's largest AI chip, 56 times larger than GPUs. This architecture allows Cerebras to deliver industry-leading training and inference speeds; over 10 times faster than GPU-based hyperscale cloud inference services. This order of magnitude increase in speed is transforming the user experience of AI applications, unlocking real‑time iteration and increasing intelligence via additional agentic computation. Cerebras works with the leading model labs, global enterprises, and cutting‑edge AI‑native startups. OpenAI recently announced a multi‑year partnership with Cerebras, to deploy 750 megawatts of scale, transforming key workloads with ultra high‑speed inference.

About The Role

As a Network Architect on the Cluster Architecture Team, you will work closely with the vendors, internal networking teams and industry peers to develop best‑in‑class front‑end data‑center and interconnect architecture of the current and future generations of the Cerebras AI clusters. You will be responsible for developing proof‑of‑concept of new network designs and features enabling resilient and reliable network for AI workloads. The role will require cross‑functional collaboration and interaction with diverse hardware components (e.g., network devices and the Wafer‑Scale Engine) as well as software at several layers of the stack, from host‑side networking to cluster‑level coordination. The role also requires understanding of network monitoring systems and network debugging methodologies.

Responsibilities
