Meticulous is growing revenue exceptionally fast with leading companies adopting the tool at record pace.\nWe’ve brought together a small team of some of the most talented engineers in the world. This has allowed us to build a technology that fully autonomously and exhaustively tests frontend codebases.\nSuch a capability has never existed before, and no other company is even close to building such a capability - it’s built on the back of a range of novel technologies and research (hint: the core itself doesn't use transformers or LLMs, but something more novel).\nAs a result the demand for the product has been immense. In addition to being one of the fastest growing companies, customers like Dropbox, Wiz, Notion are often paying more for Meticulous than any other vendor or software product - and then spontaneously referring us to other companies.\nWe believe that autonomous and exhaustive testing is the missing piece in unlocking the full potential of code generation, and automating the majority of software development.\nWe are a team of ten onsite in London. We believe in building a small but extremely talented team.\nWe are hiring in London and are considering opening up Forward Deployed Engineering roles in San Francisco shortly. If either role sounds interesting please apply to this job posting here.\nWhat you may work on:\nBuild a distributed system to concurrently replay thousands of sessions, such that a developer gets a result in seconds.\n\nIntegrate Meticulous into the inner loop of agentic code generation, to produce a coding agent far beyond anything that exists today - by giving it a feedback loop to understand the exhaustive impact of every change it makes and iterate against; while also allowing it to understand the full runtime behaviour of the code it’s editing and space of data and edge cases it may operate over.\n\nDerive algorithms to detect sessions that cover differing code paths and edge cases, and ignore sessions that are too similar.\n\nWork directly with engineering leaders across the world's top technology companies to help them deploy Meticulous to their organisations.\n\nWhat you get from working here:\nWorld-class compensation, exceeding top technology companies and startups.\n\nWork with exceptional colleagues to solve novel and exceedingly difficult problems and change the way the world develops software. Work with some of the very best engineers who were previously at Uber, Google, Dropbox, GitHub, Meta and Palantir, including previously leading 100+ engineer organisations at these companies.\n\nExpand your network - Guillermo Rauch (founder of Vercel), Jason Warner (CTO of GitHub), Calvin French-Owen (founder of Segment), Jared Friedman (YC partner and founder of Scribd), Scott Belsky (CPO of Adobe), Arash Ferdowsi (founder of Dropbox) and many others are all personal investors in Meticulous. We can connect you with anyone in the technology world.","description_format":"text","description_chars":2986,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Software Testing & QA"],"lifecycle":[{"event":"open","at":"2026-09-12T11:59:26Z"},{"event":"open","at":"2026-09-25T20:35:26Z"}],"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":"2026-11-04T06:27:35+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.178,"p_room":0.28,"age_days":546,"expected_fill_days":30,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-11-04T06:34:25Z"},"pay":{"stated_usd_annual":401573,"is_top_pay":true},"html_url":"https://alion.io/job/meticulous-software-engineer","json_url":"https://alion.io/job/meticulous-software-engineer.json","meta":{"generated_at":"2026-11-04T17:44:00Z","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":27158,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-05T00:00:00Z"}},"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":679700},"rest":"https://alion.io/mcp/rest/get_company?id=679700"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmeticulous-software-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%2Fmeticulous-software-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%2Fmeticulous-software-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/meticulous-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmeticulous-software-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":818297}},{"tool":"search_jobs","arguments":{"company":"meticulous.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":818297},"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.
