You will model real-world workloads, predict system behaviour, and provide insights that guide how our platform evolves.\nSuccess in this role requires not only strong technical depth, but also the ability to work closely with multiple teams to ensure the simulator reflects reality and drives meaningful decisions.\nThe Team \nThe Tenjin team focuses on building advanced simulation capabilities to model and predict the behaviour of large-scale ML workloads on next-generation hardware and software platforms.\nWe operate at the intersection of machine learning, systems, and architecture, developing tools that enable data-driven decisions long before systems are fully built or deployed. Our work helps shape both hardware and software direction by providing early insights into performance, scalability, and efficiency.\nThe team brings together engineers with backgrounds in simulation, ML systems, and computer architecture. We collaborate closely with ML engineers, performance teams, and silicon architects, but operate as an independent group focused on simulation as a core capability.\nResponsibilities and Duties\nDesign and evolve an ML application-level simulator that models workload execution, system behaviour, and resource usage\nTranslate real-world workloads and benchmarking data into accurate simulation models\nValidate simulator outputs against real system measurements and continuously improve fidelity\nBuild scalable, maintainable components that support evolving hardware and software capabilities\nWork closely with performance engineers, ML teams, and silicon architects to ensure the simulator reflects real use cases\nDrive adoption of the simulator as a decision-making tool across the organisation\nCandidate Profile \nEssential:\nStrong C++ development experience, especially in performance-sensitive or large-scale systems\nStrong Python skills and familiarity with ML frameworks (e.g. PyTorch) and execution graphs\nSolid understanding of computer architecture, memory hierarchy, and heterogeneous systems\nFamiliarity with ML accelerator concepts (e.g. tensor cores, compute tiles, high-bandwidth memory)\nDesirable\nUnderstanding of modern ML architectures (e.g. transformers, MoE) in training and inference\nExperience with simulators or performance models (hardware or distributed systems)\nKnowledge of parallelism models and their mapping to hardware\nExperience with profiling and debugging complex, multi-layer systems\nBenefits\nIn addition to a competitive salary, Graphcore offers annual leave policy, medical and dental health plans, a gym card, and employee pension (matched up to 4%). We review our benefits on a yearly basis to ensure we offer a valuable and rewarding benefits programme to our employees. 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":4237,"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"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Processors, MCUs & AI Chips","AI Chips & Accelerators"],"lifecycle":[{"event":"open","at":"2026-05-15T15:11:46Z"}],"visa":[],"liveness":{"score":17,"band":"cold","label":"Long shot","p_open":1,"p_active":0.608,"p_room":0.28,"age_days":154,"expected_fill_days":69,"reasons":["conf:3","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":90061,"is_top_pay":false},"html_url":"https://alion.io/job/graphcore-senior-software-engineer-2","json_url":"https://alion.io/job/graphcore-senior-software-engineer-2.json","meta":{"generated_at":"2026-10-18T07:00:02Z","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":10399,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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-senior-software-engineer-2"},{"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-senior-software-engineer-2"},{"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-senior-software-engineer-2"},{"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-senior-software-engineer-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fgraphcore-senior-software-engineer-2"}]}
