We make powerful AI systems safe to deploy, a problem that gets more urgent as AI becomes more capable and autonomous. Backed by leading investors, with IOI/IMO medalists, top-university PhDs, best-paper winners, and advisors holding top prizes in CS and AI, including a Turing Award holder.\nYou'll look closely at what AI agents actually do: reviewing their transcripts, judging their behaviour, and building the datasets our research and customer work rely on. It's focused, detail-heavy work, and it suits someone who enjoys getting things exactly right.\nWhat you'll work on\nReview transcripts of AI agents using tools and judge whether they behaved correctly, safely and as intended\n\nBuild “gold” datasets: carefully labelled reference examples we use to evaluate AI systems and our automated judges\n\nPre-select and prepare examples for customer reports, with a senior researcher giving final sign-off\n\nSpot patterns, edge cases and inconsistencies, flag them to researchers and help sharpen the guidelines\n\nNot a rubric-ticking labelling job: you'll learn what we're working on and use your own judgement when a case doesn't fit the rules\n\nWhat we look for\nReliable and high-integrity — you care about the quality of what you hand over; we'll trust your judgement\n\nQuick to understand — picks up new topics fast, notices nuance and small details\n\nCareful and patient — comfortable spending most of the week reading data closely\n\nTechnical background — ideally you've completed at least one computer science or data science course\n\nStrong English reading comprehension\n\nBonus\nSome previous work experience, ideally where precision matters (banking, for example)\n\nInterest in AI and how modern AI systems are evaluated\n\nAble to start soon\n\nWhat we offer\nA close look at how AI safety research works, side by side with a top-tier team\n\nCompetitive compensation\n\nPart-time: 30 hours a week as a baseline, some weeks noticeably more. We guarantee an average of at least 30 hours a week every month\n\nOffice in the centre of Prague\n\nCatered lunch and a fully stocked office kitchen\n\nPlenty to learn along the way, from how AI agents work to how they're evaluated","description_format":"text","description_chars":2284,"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":["Operating Systems","Streaming & OTT Platforms"],"lifecycle":[{"event":"open","at":"2026-11-13T02:41:34Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":26,"reasons":["seen:0","win:early"],"computed_at":"2026-11-13T03:24:05Z"},"pay":null,"html_url":"https://alion.io/job/stealth-data-specialist","json_url":"https://alion.io/job/stealth-data-specialist.json","meta":{"generated_at":"2026-11-13T03:24:05Z","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":7117,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-14T00:00:00Z"}},"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":30930},"rest":"https://alion.io/mcp/rest/get_company?id=30930"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fstealth-data-specialist"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Fstealth-data-specialist"},{"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%2Fstealth-data-specialist"},{"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/stealth-data-specialist\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fstealth-data-specialist"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4215866}},{"tool":"search_jobs","arguments":{"company":"stealth.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4215866},"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.
