Senior / Lead Verification Engineer

About the company: Anthriq is a signal processing infrastructure company. We build the full acquisition and compute stack for human-aware technology — from custom analog front-end IP that captures biosignals at the source, to signal-first compute systems built for time-critical, deterministic workloads. Our infrastructure is designed around one principle: the signal should never be the bottleneck. General-purpose processors — CPUs, GPUs, DSPs — were not built for this class of problems. They approximate determinism. We built it in by architecture. Anthriq Silicon is our ground-up effort to build a new compute category. About the Role We are building a high-performance signal processing ASIC — a multi-core vector processor with a custom ISA, targeting defense, 5G, and test & measurement markets. As a Senior/Lead Verification Engineer, you will own functional verification for major subsystems of the chip, from testbench architecture through coverage closure. You will work closely with RTL designers and the architecture team to build the verification environments, assertions, and test plans that prove the design matches spec before it goes to silicon, and will help set verification methodology and mentor other engineers on the team. Responsibilities - Verify RTL blocks across Anthriq's custom multi-core vector processor — execution units, register files, datapath pipelines, and arithmetic units (integer, fixed-point, floating-point, complex) - Develop UVM-based SystemVerilog testbenches for the on-chip network, switch fabric, PCIe endpoint, DMA engines, and inter-core synchronization engine - Write directed and constrained-random test cases targeting custom ISA opcodes, data types, and pipeline hazard scenarios - Write SVA assertions for protocol compliance across AXI4-Lite bus fabric, credit-based flow control, and virtual channel logic - Verify clock domain crossings async FIFOs, gray-code pointers, 2FF synchronizers across all subsystem boundaries - Verify the RISC-V system management controller — boot flow, reset sequencing, phased initialization, and mode switching - Drive functional and code coverage closure across all execution unit opcodes and supported data types - Debug RTL failures across the full design hierarchy — waveform tracing, root-cause analysis, and tracking to resolution with RTL engineers - Build and maintain regression suites for multi-core coordination, barrier logic, and event distribution scenarios - Verify PCIe endpoint and NoC (network-on-chip) — TLP handling, credit flow control, virtual channels - Verify microprocessor/RISC-V core-level functionality — instruction execution, pipeline behavior, and processor compliance - Automate test generation and regression analysis using Python or TCL scripting Requirements - 5 to 10 years of RTL verification experience in ASIC or SoC environment - Strong SystemVerilog and UVM — testbench architecture, sequences, scoreboards, monitors, functional and code coverage - SVA assertion writing from architecture specifications — not just consuming existing assertions - Protocol knowledge — AXI4, AHB, APB; PCIe TLP handling a strong plus - Hands-on with simulation tools — VCS, Xcelium, or Questa - Strong debugging skills — comfortable tracing failures across deep design hierarchy in Verdi or SimVision - Understanding of processor pipelines — hazard detection, data forwarding, multi-cycle operations - Python or TCL scripting for regression automation and test generation - Ability to work independently from a detailed architecture specification - SoC, NoC, PCIe, and microprocessor-level verification experience Nice to Have - Formal verification — JasperGold, VC Formal, or Questa Formal for exhaustive property checking on arithmetic units and control logic - Floating-point verification experience — IEEE 754 corner cases, rounding modes, denormals, NaN propagation - CDC verification depth — async FIFO design checking, synchronizer verification
