Senior Silicon Engineer

Department: Engineering

Location: San Francisco

Employment Type: FullTime

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.
