About Etched

Co-designed chips, racks, and software to push the pareto frontier to best-in-class throughput and interactivity. Backed by Kleiner Perkins and Sequoia.

About the role

Etched is building a new category of AI hardware: frontier inference clusters. As a top-level PD engineer, you will own full-chip implementation—encompassing floorplanning, P&R, clocking, timing analysis, physical verification, and sign-offs—from synthesis through to GDSII completion. You will lead critical efforts in these areas, leveraging our PD flows to drive aggressive PPA optimization and timing closure.

What they're looking for

  • 10+ years of previous experience with chip planning, top level PD, floorplanning
  • Experience with top-level and full-chip closure on advanced process nodes (5nm and below)
  • Experience with Cadence (Innovus, Genus) or Synopsys (Fusion Compiler) automated RTL-to-GDSII flows
  • Experience with Synopsys PrimeTime and Cadence Tempus for timing signoff
  • Experience with Pegasus or Calibre for physical verification signoff
  • Experience with hierarchical timing budgeting, constraint management, and ECO closure
More about this role

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.
