Head of Performance Visibility

About the Company

Etched is building hardware for frontier intelligence. We co-design chips, racks, software, and manufacturing to deliver best-in-class throughput and latency across both prefill and decode workloads. Our first products are heavily focused on inference. Backed by hundreds of millions from top-tier investors and staffed by leading engineers, Etched is redefining the infrastructure layer for the fastest growing industry in history.

Responsibilities

• Define the architectural approach for collecting and structuring telemetry across CPUs, drivers, interconnects, and multiple accelerators
