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.
