We bet everything on the logical conclusion: that the only way to truly unlock this latent value, to make speed viable at scale, was to radically re-invent the hardware that we run our frontier AI models on. Ever since, we have been building chips and systems that tackle this problem: how to efficiently generate output at thousands of tokens per second, while handling the complexity and capacity challenges of operating large models at very long contexts.\nThe workloads that push to the limits of the current frontier are already transformational; it is the technical and economic limits on inference speed that are constraining progress. The defining work of the 21st century will be marked by the engine of inference delivering immense and diffuse chains of intellectual inquiry, in drug discovery, in software engineering, in materials discovery, in any field where progress is driven by deep reasoning and intelligence to resolve complex problems. \nAbout the Hardware organisation at Fractile\nProcessor Architecture sits within Fractile’s hardware organisation, which owns everything from compute engine definition and ISA design through memory hierarchies, on-chip interconnects, and the path from early architectural exploration through to tapeout and post-silicon validation. Architecture at Fractile isn’t a paper exercise - it’s built in constant collaboration with logical design, physical design, and verification teams, so that every architectural decision is grounded in what will actually perform in working silicon.\nAbout the team and role\nAs an Early Career Processor Architect, you’ll join our architecture team to learn how to define the compute engines, ISA definitions and programming models that sit at the heart of our silicon. Working closely with senior architects and our logical design, physical design, and verification teams, you’ll get real exposure to performance modelling, specification writing, bottleneck analysis, and pre- and post-silicon validation - with experienced architects mentoring you as you build toward owning more of this yourself.\nAbout you\nWe’re looking for someone with a strong foundational understanding of computer or processor architecture - built through coursework, personal projects, internships, placements, or research - who’s genuinely curious about performance and power trade-offs and eager to learn how to navigate them. You don’t need prior industry experience as a Processor Architect; what matters is real hands-on exposure to processor or accelerator design, through a final-year project, FPGA build, RISC-V implementation, internship, or research, plus a comfort working across disciplines and a track record of thriving in ambiguity and fast iteration.\nKey Requirements\nA degree (BEng, MEng, MSc or equivalent) in Electronic Engineering, Computer Engineering, Computer Science, or a related field - or equivalent practical experience.\n\nA solid foundational understanding of computer/processor architecture, including matrix- and vector-centric floating-point arithmetic and memory hierarchies, gained through study, projects, internships, or research.\n\nSome exposure to RTL design concepts and how physical design constraints feed back into architectural choices - academic or internship-level experience is fine.\n\nAny hands-on exposure to architectural performance modelling tools (gem5, SystemC, or custom cycle-accurate simulators), compiler/toolchain interactions, or AI acceleration/vector-matrix compute, through study or projects, is highly valued.\n\nA clear communicator, comfortable working across architecture, modelling, implementation, verification, and software teams, who thrives in ambiguity and fast iteration.\n\nWhat We Offer\nCompetitive salary: A competitive salary reflective of your experience and the specialist nature of the role.\n\nEquity & Ownership: meaningful equity so everyone shares in the value creation\n\nBenefits: Private Medical, Dental and Vision, Contributory Pension, 25 Days holiday plus bank holidays and Life/Critical Illness Insurance.\n\nDiverse & fun office: we believe the hardest problems get solved by the broadest range of minds. We are committed to Equal Employment Opportunity through attracting and retaining a diverse team and building an inclusive environment.\n\nFractile is seeking to increase the clock speed of global progress, one chip at a time. We’ve recently raised $220M from investors including Founders Fund and Accel and our most important work lies ahead. Join us!\n Export controls\nOur work involves technologies subject to UK, US and other international export control regulations. Certain roles may require additional eligibility checks to ensure compliance with applicable law. We'll be transparent about this throughout the hiring process.","description_format":"text","description_chars":4959,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Foundation Models","AI Compute & Inference","AI Chips & Accelerators"],"lifecycle":[{"event":"open","at":"2026-11-05T01:59:07Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"adverts_offering_sponsorship_24m":0,"sanctioned_now":false,"evidence":"Licensed UK visa sponsor (Skilled Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Skilled Worker","cap_exempt":false,"checked_at":"2026-11-10T06:21:00+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":11,"expected_fill_days":160,"reasons":["conf:3","velocity","win:early","comp:junior"],"computed_at":"2026-11-10T06:52:35Z"},"pay":null,"html_url":"https://alion.io/job/fractile-early-career-compute-architect","json_url":"https://alion.io/job/fractile-early-career-compute-architect.json","meta":{"generated_at":"2026-11-10T07:06:06Z","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":16497,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-11T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":51523},"rest":"https://alion.io/mcp/rest/get_company?id=51523"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffractile-early-career-compute-architect"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Ffractile-early-career-compute-architect"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Ffractile-early-career-compute-architect"},{"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/fractile-early-career-compute-architect\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffractile-early-career-compute-architect"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3783079}},{"tool":"search_jobs","arguments":{"company":"fractile.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3783079},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
