About the role

View original

At Zetta, we're building the next NVIDIA to accelerate AI discovery. Our XPU chips are state-of-the-art AI compute engines , versatile and efficient enough to support AGI , and eventually ASI , without requiring massive power infrastructure.

We're a small founding team of engineers obsessed with pushing the boundaries of compute, and we're looking for the person who will own our chip design : from FPGA prototypes today to real silicon tapeouts tomorrow.

You Are

Scrappy. You'd rather have a design running on hardware this week than a perfect spec next quarter

Ready to go all-in and do the work of your life

A technical powerhouse who loves living at the hardware-software boundary

Hungry to own a chip end-to-end : architecture, RTL, verification, bring-up

Deeply passionate and obsessed with computing and AI

Someone who doesn't fret when faced with near-impossible technical challenges

Your Background (important in bold)

  • Background in Electrical Engineering, Computer Engineering, or you taught yourself and can prove it

  • Strong digital design fundamentals (RTL, pipelining, clocking/reset strategy, latency vs. throughput tradeoffs, clean microarchitecture)

  • Hands-on FPGA experience : you've taken real designs from RTL to running on a board (Xilinx/AMD or Intel/Altera), debugged timing failures at 2am, and shipped something that worked

  • Synthesizable SystemVerilog/Verilog you're proud of : side projects, university work, open-source contributions, or professional experience all count

  • Toolchain fluency : simulation (Verilator, VCS/Xcelium/Questa, or open-source flows), linting, synthesis, timing constraints (SDC), and iterating toward timing closure

  • RTL quality instincts (assertions, CDC awareness, X-prop, code review hygiene, or the drive to build these habits fast)

  • Build/flow automation (Python, Tcl, bonus points for Nix or Makefile wizardry)

  • Comfort designing compute datapaths and memory subsystems : you understand bandwidth/latency-driven design even if you haven't shipped an AI accelerator yet

  • Huge Plus If

  • Tapeout experience : university shuttle (Tiny Tapeout, MPW, Efabless), research chip, or professional. Any real silicon counts, and if you haven't taped out yet, this role is your path to it

  • FPGA prototyping of large designs (partitioning, multi-FPGA, emulation-style flows)

  • HW/SW bring-up experience (drivers/firmware, performance counters, profiling, debugging across the stack)

  • High-speed interface/IP integration (PCIe, DDR/HBM, Ethernet, SerDes)

  • Verification depth (UVM, formal, or cocotb-style Python testbenches)

  • Systems programming (Linux kernel modules, low-level software)

  • Autodidactic polymath with a strong mathematical background

What You'll Actually Do

  • Own the FPGA prototype of our XPU architecture: get it running, keep it running, make it fast

  • Write and review the RTL that becomes our first ASIC

  • Drive us to tapeout by building the design flow (lint, sim, synthesis, constraints) that gets us to real silicon

  • Work across architecture, verification, and physical design to hit PPA targets

  • Make critical architectural decisions that will live in silicon for years

  • The Opportunity

  • Be one of the first employees shaping a revolutionary technology

  • Go from FPGA prototype to your name on a tapeout . Few roles anywhere offer that arc this early in a career

  • Work directly with the founding team at our San Francisco HQ

  • Grow into the technical leader of our chip team as we scale

  • Highly competitive compensation + significant equity

  • This is THE chance to do the work of your life. The chance to put your architecture into real silicon. To go hardcore on a technical moonshot that will actually matter for over 100 to 1,000 years.
