Senior Silicon Engineer

ABOUT THE ROLE Lead silicon design for an AI accelerator, taking designs from FPGA prototypes through ASIC tapeout and bring-up. As a senior member of a small hardware team, you will shape technical direction across architecture, RTL, verification, and tooling, working closely with PCB, interconnect, software, and systems teams. WHAT YOU'LL DO - Lead FPGA prototype development and optimization, from design specifications through deployment on working hardware. - Design and review synthesizable RTL for an ASIC, with a focus on clean microarchitecture. - Build and improve 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, contributing hands-on during critical periods. - Mentor teammates and help grow the silicon engineering 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 in production silicon or FPGA designs, and taking FPGA designs from RTL through synthesis, place-and-route, and deployment to working hardware. - Strong understanding of digital design, including pipelining, clocks, resets, latency, throughput, and microarchitecture. - Experience designing compute datapaths and memory systems with bandwidth and latency constraints. - Hands-on experience with simulation, linting, synthesis, SDC constraints, timing closure, and CDC verification. - Experience automating hardware flows with Python, Tcl, Make, Nix, or similar tools, plus background in AI accelerators or low-level AI kernels. - Tapeout experience, high-speed interfaces, formal verification, UVM, cocotb, firmware, or systems-level hardware drivers are valuable. COMPENSATION & BENEFITS Base salary is $200,000 to $300,000 USD annually. Visa sponsorship is available. LOCATION Full-time, on-site role in San Francisco, United States. This position is not remote or hybrid.
