Responsibilities

Set the multi-generation architecture and roadmap for Cerebras scale-up networks and their interfaces to scale-out and customer-facing networks.
Work with application, compiler, runtime, and communication-library teams to understand mapping and communication choices, then derive the required bandwidth, latency, ordering, availability, and serviceability.
Define fabric topology, protocols, and switch behavior, including routing, buffering, flow control, reliability, and fault containment. Connect data-plane choices to end-to-end system behavior.
Decide when to use standards-based technology or merchant silicon and when a custom protocol, switch, link, or offload is justified.
Use performance models, traffic simulation, prototypes, and lab data to test architecture choices and set acceptance criteria.
Write architecture and interface specifications, lead design reviews, and drive cross-layer decisions through implementation, bring-up, and qualification.
