On-siteQuality AssuranceFull-time

About the role

You verify the blocks and subsystems of a first-of-its-kind chiplet — building UVM testbenches, writing tests, and driving coverage to closure. Guided by the verification plan and methodology, you take assigned blocks from testbench bring-up through coverage signoff, and help debug across simulation and emulation.

Responsibilities

  • Build and extend UVM testbenches (agents, sequences, scoreboards) for assigned blocks and subsystems.
  • Write directed and constrained-random tests; develop functional coverage and drive it to closure.
  • Verify the in-house engines against an algorithmic golden model, with programmable error injection and error-pattern coverage.
  • Integrate and use VIP (e.g., UCIe) and run compliance, link-training, loopback, and lane-repair scenarios.
  • Run regressions, triage failures, and help maintain the CI/regression flow.
  • Register (UVM RAL) verification, firmware co-simulation, and boot flows on the MCU subsystem.
  • Mixed-signal co-simulation — verifying digital blocks against behavioral / real-number models of analog/mixed-signal blocks.
  • Support hardware-assisted verification — bring up and run tests on emulation / FPGA prototyping.
  • Participate in gate-level and low-power (UPF) verification during signoff.
  • Collaborate with the design, architecture, modelling, and DFT teams as your blocks move through the flow.

Requirements

  • BS or MS in Electrical/Computer Engineering (or equivalent experience).
  • 3+ years of ASIC/SoC functional verification.
  • Solid UVM/SystemVerilog; constrained-random and coverage-driven verification.
  • Testbench development and coverage closure — building block/subsystem testbenches and driving functional + code coverage to closure.
  • Strong debug skills across simulation; scripting in Python, Perl, or TCL.
  • Familiarity with regression/CI flows and failure triage.

Preferred

  • High-speed SerDes, PAM4, or FEC/coding (Reed-Solomon) verification.
  • UCIe, PCIe/CXL, Ethernet, or UALink VIP / compliance experience.
  • Mixed-signal verification (Verilog-AMS or SV real-number models).
  • Hardware-assisted verification — emulation (e.g., Palladium/Veloce) and/or FPGA prototyping (e.g., HAPS/Protium).
  • Low-power/UPF and gate-level simulation; performance-verification methodology.
  • Exposure to NICs, Ethernet/IB switches, or cache-coherent fabrics (multi-core / coherent fabric).
  • Formal verification for control/interlock logic; portable stimulus.
