Think semiconductor-fab levels of precision applied to the chaotic world of prototyping and low-volume production. The result? A 10x throughput improvement in one of the world's most foundational industries.\nWe've raised $48M from top-tier investors, including Y Combinator, Google Ventures and now Plural and Sten Tamkivi, and we're already profitable. Our customers include industry leaders like Tesla, Meta, and Zipline.\nThe Grid isn't a prototype. It's live, scaling fast, and delivering real revenue. We're now building the engineering core that will scale it further.\nOverview\nCircuitHub is primarily built using a combination of Haskell, Nix, and PostgreSQL, deployed to both AWS and bare metal machines. We use a significant amount of open-source technology, and also try and give back where possible (for example, both Rel8 and Fast Downward Haskell bindings).\n\nCircuitHub spans a vast problem space. Challenges include computer vision (OpenCV), machine learning (PyTorch), hard optimization problems (Z3/MiniZinc/OR-Tools), and all the normal engineering challenges of building both web-based customer-facing and internal tooling.\n\nWe work on manufacturing execution systems, enterprise resource planning, and robotics. An old video from Haskell Exchange 2019 hints at what we are up to on the robotics side. We have progressed significantly since then!\n\nThese roles are remote (any location), in-person, or hybrid, depending on preference.\n\nWe have offices in South Deerfield - USA, Cambridge, and London, UK.\n\nSalary depends on the candidate and location, but as guidance in the UK, a likely range is £70k to £130k and in the US $130k to $250k, with additional equity.\n\nCircuitHub has raised $48M from top-tier VCs and has been going for about ten years. CircuitHub is profitable, with tens of millions in revenue. Small team (CircuitHub is ~50 employees) with tremendous growth opportunity and low risk. We are aiming to 10x capacity through 2027 in both our existing Massachusetts factory and expand into Europe.\n\nTeam/Environment/Role\nOur R&D team is more than 20 people, with eight engineers working directly on the Haskell code base. We are looking to expand the team significantly this year. We have many exciting problems to solve, from robotic path planning to more conventional web products.\nWe are happy to consider candidates without commercial Haskell experience, but your other skills and experience would need to compensate. A possible profile, for instance, would be a professional robotics background with some hobbyist FP experience.\nConversely, for experienced Haskellers without experience in our domain, we will look for interests that correlate with what we are trying to accomplish. Life is too short to work on something you are not passionate about!\nLocation\nWork remotely, or from one of our labs in the UK (London, Cambridge) or USA (Boston)","description_format":"text","description_chars":3081,"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":["Equity"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"},{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Electronics Manufacturing","PCB Fabrication & Assembly"],"lifecycle":[{"event":"open","at":"2026-07-24T11:45:22Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"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":"2026-10-16T06:21:30+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":0.412,"p_room":0.28,"age_days":83,"expected_fill_days":38,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-16T05:45:00Z"},"pay":{"stated_usd_annual":171817,"is_top_pay":false},"html_url":"https://alion.io/job/circuithub-haskell-engineer","json_url":"https://alion.io/job/circuithub-haskell-engineer.json","meta":{"generated_at":"2026-10-16T18:54:01Z","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":4255,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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":17915},"rest":"https://alion.io/mcp/rest/get_company?id=17915"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcircuithub-haskell-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%2Fcircuithub-haskell-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%2Fcircuithub-haskell-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/circuithub-haskell-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcircuithub-haskell-engineer"}]}
