About the role

  • At Nexthop AI, the correctness of our digital logic is non-negotiable - a single functional escape in an FPGA or ASIC can compromise an entire switching platform once it ships.

Responsibilities

  • Own the testbench: Design, build, and maintain the verification environments for our digital subsystems - from block level through full-chip / subsystem integration - for both FPGA and ASIC targets.
  • Reference modeling: Develop behavioral / reference models where needed to independently predict expected DUT behavior and catch discrepancies automatically.
  • triage failures to root cause and partner with RTL designers on the fix.
  • Regression: Stand up and maintain automated regression suites - keeping them fast, deterministic, and green so the team gets rapid feedback on every RTL change.
  • Waveform debug: Debug efficiently at the waveform level and produce clear, reproducible failure reports that shorten the design-debug loop.

Requirements

  • Tools: Hands-on experience with logic simulators - Modelsim / Questasim and/or NC-Verilog.
  • Experience collaborating with software / firmware teams on system bring-up and HW/SW co-validation.
  • Familiarity with networking / switching datapaths or high-speed interfaces.

Nice to have

  • Proficiency in Verilog (SystemVerilog strongly preferred).
  • Language: Proficiency in Verilog (SystemVerilog strongly preferred).

Skills

  • Hands-on experience with logic simulators - Modelsim / Questasim and/or NC-Verilog.

Benefits

  • Test Development & Coverage
  • Coverage-driven closure: Define functional and code-coverage goals and drive them to closure - identifying coverage holes and writing the stimulus to fill them.

Company info

  • Fast, deterministic regressions catch breakage the same day it's introduced, so designers refactor with confidence.
