We ensure that the RTL delivered by Logical Design and used by Physical Design team implements Graphcore’s architectural needs and meets the company's quality standards. As a Director of Silicon Verification, you will help lead this multi-site organisation, define verification strategies across multiple silicon programs, and drive best in class execution to ensure high-quality, high-performance silicon delivery. \nRole Summary \nWe are seeking a proven leader to help direct Graphcore’s verification strategy and methodologies. This role sets direction for the verification lifecycle including - planning, infrastructure, execution, coverage closure, debug strategy and sign-off for Graphcore’s complex, high performance AI accelerators. \nReporting to the Senior Director of Verification the Director will partner closely with other teams such as Architecture, Logical Design, Physical Design, DFT, Systems as well as Program Management teams to ensure accurate implementation, accelerated debug cycles, high coverage confidence and predictable silicon delivery. \nResponsibilities \n Leadership & Strategy \nDefine the long-term vision, roadmap and strategy for silicon functional verification across all Graphcore silicon programs. \nBuild, lead, and develop a high performing, globally distributed verification organisation. \nEstablish scalable methodologies, leading edge verification techniques, and best practice processes. \nDrive automation, tooling and infrastructure evolution to improve productivity and verification quality. \nEvaluate emerging tools and technologies and drive adoption to deliver competitive advantage. \n Technical Ownership \nOwn verification planning, execution and sign off for all RTL blocks and top-level SoCs. \nOversee definition of test plans including functional coverage targets. Drive close through prioritisation of test content and coverage signoff. Iterate plans to close verification gaps. \nDirect debugging strategies, triage processes and root-cause analysis workflows to enhance team productivity. \nSteer integration of verification technologies including formal methods, simulation acceleration/emulation and system level validation. \n\nCross Functional Collaboration \nEnsure high quality feedback to other functions within the Silicon Team. \nPartner with Architecture to influence and refine specifications for verifiability and risk reduction. \nCollaborate with Logical Design to align on design intent, architectural corner cases and test scenarios. \nWork closely with Physical Design and DFT teams to ensure coherent verification of interfaces, timing assumptions and test structures. \nLead post-silicon debug alignment where needed, ensuring learning cycles feed back into RTL and verification methodology. \nExecution & Delivery \nDeliver verification sign off on schedule across multiple parallel projects. \nGuide program risk management, resource planning, milestone creation, and verification budgeting. \nDrive consistent metrics-based verification management (structural and functional coverage, bug funnels, simulation performance, CI health, etc.). \nProvide scheduled reports into program management on progress with associated metrics based collaterol. \nEssential Skills \nDemonstrated ability to lead, scale and inspire high performing verification teams. \nExtensive verification leadership experience within CPU, GPU, ASIC or SoC environments. \nDeep understanding of modern verification methodologies, flows, and infrastructure. \nStrong capability in SystemVerilog, Python, C++ and Linux-based workflows. \nExpertise in diagnosing complex logic issues across RTL, testbench and system level domains. \nStrong communication, collaboration and stakeholder management skills across global sites. \nDesirable Skills \nUVM and advanced SystemVerilog Assertions (SVA). \nExperience with assembly languages and compiler toolchains (LLVM, GCC). \nKnowledge of DVCS tools (e.g., Git). \nFamiliarity with distributed compute systems (SGE or other DRMS). \nExperience with XML, XPath/XSLT. \nWeb technologies such as HTML/DOM, JavaScript, SQL. \nExposure to emulation, FPGA prototyping, or formal verification tools. \nBenefits\nIn addition to a competitive salary, Graphcore offers flexible working, a generous annual leave policy, private medical insurance and health cash plan, a dental plan, pension (matched up to 5%), life assurance and income protection. We have a generous parental leave policy and an employee assistance programme (which includes health, mental wellbeing, and bereavement support). We offer a range of healthy food and snacks at our central Bristol office and have our own barista bar! We welcome people of different backgrounds and experiences; we’re committed to building an inclusive work environment that makes Graphcore a great home for everyone. We offer an equal opportunity process and understand that there are visible and invisible differences in all of us. We can provide a flexible approach to interview and encourage you to chat to us if you require any reasonable adjustments.","description_format":"text","description_chars":5846,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Annual leave","Flexible schedule","Health insurance","Parental leave"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Processors, MCUs & AI Chips","AI Chips & Accelerators"],"lifecycle":[{"event":"open","at":"2025-12-10T11:30:58Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"evidence":"Licensed UK visa sponsor (Senior or Specialist Worker, Skilled Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Global Business Mobility: Senior or Specialist Worker; Skilled Worker","cap_exempt":false,"checked_at":"2026-10-17T06:21:15+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":8,"band":"cold","label":"Long shot","p_open":1,"p_active":0.3,"p_room":0.28,"age_days":310,"expected_fill_days":69,"reasons":["conf:3","velocity","ghost","win:tail","crowd:brand"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/graphcore-director-silicon-verification","json_url":"https://alion.io/job/graphcore-director-silicon-verification.json","meta":{"generated_at":"2026-10-17T21:01:53Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":5437,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":33},"rest":"https://alion.io/mcp/rest/get_company?id=33"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fgraphcore-director-silicon-verification"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fgraphcore-director-silicon-verification"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fgraphcore-director-silicon-verification"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/graphcore-director-silicon-verification\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fgraphcore-director-silicon-verification"}]}
