As part of our Ultra Low Latency team, you’ll have the opportunity to collaborate with people in areas across the firm, including trading, networking and research infrastructure. We are looking for someone who can contribute to all of our projects and be happy to work on both FPGA-based and ASIC-based technologies.\nWe’re big believers in the ability of tools to improve the productivity, reliability and day-to-day joy of hardware engineering. That’s why we created Hardcaml, a hardware development toolchain embedded in OCaml. We don’t expect you to know OCaml (we’ll teach you here), but we are looking for hardware engineers who are excited about the advantages that better tools can bring, and are willing to try new things as a result.\nAbout you\n4+ years of practical experience in RTL design and verification, with a significant focus on ASIC design verification.\nExperience verifying ASIC designs using either Synopsys or Cadence tools.\nExperience applying software engineering techniques to improve the hardware design process and programming in high-level languages such as Python, C++, Java, or Haskell.\nAdditional (preferred) experience in any of the following; formal verification, front-end RTL design and synthesis, or back-end physical design.\nFluent in English\nIf you're a recruiting agency and want to partner with us, please reach out to .","description_format":"text","description_chars":1526,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Machine Learning","Financial AI"],"lifecycle":[{"event":"open","at":"2026-09-10T14:59:02Z"}],"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":12,"band":"cold","label":"Long shot","p_open":1,"p_active":0.432,"p_room":0.28,"age_days":352,"expected_fill_days":141,"reasons":["conf:0","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/janestreet-dev-asic-engineer","json_url":"https://alion.io/job/janestreet-dev-asic-engineer.json","meta":{"generated_at":"2026-10-18T00:24:42Z","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":747,"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":7349},"rest":"https://alion.io/mcp/rest/get_company?id=7349"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fjanestreet-dev-asic-engineer"},{"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%2Fjanestreet-dev-asic-engineer"},{"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%2Fjanestreet-dev-asic-engineer"},{"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/janestreet-dev-asic-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fjanestreet-dev-asic-engineer"}]}
