Senior Silicon Engineer

ABOUT THE ROLE Lead silicon design for an AI accelerator, guiding development from FPGA prototype through ASIC tapeout and bring-up. As a founding member of a small silicon team, you will set technical direction and collaborate with PCB, interconnect, software, and systems teams to deliver the accelerator. WHAT YOU'LL DO - Develop and optimize FPGA prototypes, taking designs from specification to working hardware. - Design and review synthesizable RTL for the first ASIC, with a focus on clean microarchitecture. - Build and maintain lint, simulation, synthesis, timing, and verification flows for rapid iteration and tapeout readiness. - Make architecture decisions across compute datapaths, memory systems, on-chip interconnect, and control logic. - Drive design through tapeout, bring-up, and delivery milestones. - Help grow and mentor the silicon team. WHAT WE'RE LOOKING FOR - At least 8 years of experience in digital design or silicon engineering, building RTL, FPGA prototypes, or ASICs. - Experience shipping synthesizable SystemVerilog or Verilog and taking FPGA designs through synthesis, place-and-route, and deployment to working hardware. - Strong digital design fundamentals, including pipelining, clocks, resets, latency, throughput, and microarchitecture. - Experience designing compute datapaths and memory systems with bandwidth and latency constraints in mind. - Familiarity with simulation, linting, synthesis, SDC constraints, timing closure, and CDC verification. - Experience automating hardware flows with Python, Tcl, Make, Nix, or similar tools. - Background in AI accelerators or low-level AI kernels. Tapeout, high-speed interface, formal verification, UVM, cocotb, firmware, or systems-level hardware validation experience is also valuable. COMPENSATION & BENEFITS Salary range: $200,000 to $300,000 annually. Visa sponsorship is available. LOCATION On-site, full-time in San Francisco, United States. This role is not remote or hybrid.
