Verification Engineer

Job Title

Verification Engineer

Role Summary

Join Fractile's silicon verification team to develop pre-silicon verification for ML/AI ICs targeted at data-centre inference. You will work with modelling, architecture and RTL design teams to raise functional quality, improve verification workflows, and reduce tape-out risk and cost.

This role is based in one of Fractile's UK offices (Bristol or London) and involves hands-on verification engineering across RTL, testbenches and verification infrastructure.

Experience Level

Mid-level — approximately 3+ years of relevant verification or software/hardware engineering experience preferred.

Responsibilities

Primary responsibilities include planning and executing verification activities and improving verification workflows to ensure RTL meets specification and quality targets.

• Develop and execute verification plans from specification to closure.
• Design and build testbenches and stimulus for functional verification.
• Create checkers, functional models and coverage strategies; drive coverage closure.
• Debug RTL failures using waveforms and simulation infrastructure.
• Collaborate with architects, RTL designers and modelling teams to refine specifications and fixes.
• Integrate software-oriented practices into hardware verification workflows (monorepo, CI, tooling).
• Contribute to verification tooling, automation and test infrastructure (open-source and commercial tools).
• Participate in architecture and release discussions to raise product quality and reduce time-to-tapeout.

Requirements

Clear distinction between required skills and beneficial experience to perform effectively from day one.

• Must-have: Strong software skills (Python or another object-oriented language such as C++).
• Must-have: Practical understanding of digital hardware and ability to read and debug SystemVerilog RTL.
• Must-have: Familiarity with waveform-based debugging and simulation workflows.
• Nice-to-have: UVM or other verification methodology experience; pre-silicon RTL verification, verification planning and coverage closure.
• Nice-to-have: Transaction-Level Modelling (UVM/SystemC or similar) and SystemVerilog Assertions (SVA).
• Nice-to-have: Experience with cocotb, Verilator, Icarus Verilog, commercial EDA tools, or formal verification.
• Nice-to-have: Experience working in monorepo environments and familiarity with Bazel-style workflows.

Education Requirements

Not specified.
