Director, Silicon Verification

Job Title

Director, Silicon Verification

Role Summary

Lead Graphcore's silicon functional verification strategy and a globally distributed verification organisation to ensure high-quality, high-performance AI accelerator silicon delivery. The role defines verification lifecycles (planning, infrastructure, execution, coverage closure, debug and sign-off) and partners with Architecture, Logical Design, Physical Design, DFT, Systems and Program Management.

Experience Level

Senior - Director-level leadership role. The posting does not specify years of experience.

Responsibilities

Accountable for verification strategy, execution and delivery across multiple silicon programs.

• Define long-term verification vision, roadmap and scalable methodologies across Graphcore silicon programs.
• Build, lead and develop a high-performing, multi-site verification organisation.
• Own verification planning, execution and sign-off for RTL blocks and top-level SoCs; set functional coverage targets and drive coverage closure.
• Direct debug strategy, triage and root-cause workflows; lead post-silicon debug alignment where required.
• Drive automation, tooling and infrastructure improvements (simulation acceleration/emulation, CI, formal, etc.).
• Evaluate and adopt emerging verification tools and technologies.
• Collaborate with Architecture, Logical Design, Physical Design, DFT and Systems to reduce risk and align on test scenarios and interfaces.
• Manage program risk, resource planning, milestones, budgets and metrics-based verification reporting.

Requirements

Must-have technical and leadership qualifications, plus desirable skills that improve effectiveness.

• Must-have: Proven ability to lead and scale high-performing verification teams and deliver across multiple projects.
• Extensive verification leadership experience in CPU, GPU, ASIC or SoC environments.
• Deep knowledge of modern verification methodologies, flows and infrastructure.
• Strong hands-on experience with SystemVerilog, Python, C++ and Linux-based workflows.
• Expertise in diagnosing complex logic issues across RTL, testbench and system-level domains.
• Strong communication, stakeholder management and cross-functional collaboration skills in a global environment.

• Nice-to-have: UVM and advanced SVA, experience with assembly languages and compiler toolchains (LLVM/GCC), DVCS tools (Git), distributed compute systems (SGE/DRMS), XML/XPath/XSLT, web technologies (HTML/DOM, JavaScript, SQL), and exposure to emulation, FPGA prototyping or formal verification tools.
