Judgmental forecasting is about making predictions in the absence of good statistical models, often on the topics of geopolitics, business & economics, policy, and technology. Human superforecasters use reasoning and research, and we're building an AI system that does the same.\nWe have an unusually strong technical team, coming from previous work at Google DeepMind, Citadel, Foresight Data Machines, the Bank of England, Goldman Sachs, Palantir, the VGG group at the University of Oxford, and the University of Cambridge.\nAccording to Polymarket, Mantic is \"by far the best performing AI forecasting system that we are aware of\". Mantic placed 4th / 500+ people in the most recent Metaculus Cup, a leading forecasting competition. (The Atlantic, The Guardian.)\nThe role\nWe're looking for a mission-driven candidate to help us push the frontier of forecasting accuracy.\nThe role will primarily involve working with LLM agents. You'll find improvements to scaffolding and run experiments, evaluating on internal benchmarks.\nThe typical project length will be short (e.g. 1 week).\nExample activities: \nMaking new benchmarks\nExperimenting with new tools for letting LLMs express probability distributions\nBuilding out deep research agents\nAnalyzing why we made bad predictions on certain questions\nYour title will be Member of Technical Staff.\nEssential:\nStrong work ethic.\nStrong coding ability.\nExperience working on research projects.\nComfortable with statistics.\n Desired:\nExperience with LLM agent frameworks.\nExperience working in quant finance, an AI lab, an AI startup, or academic research on LLMs.\nStrong academic results.\nEvidence of exceptional ability or achievement (from any domain).\nLocation:\nIn-person, 5 days per week.\nThe Mantic offices are in Camden, on the King's Cross side.\nWe will consider visa sponsorship for exceptional candidates. Mantic has a skilled worker sponsorship licence.\nBenefits:\nGenerous equity.\nCompetitive salary.\nLunch.\nJoin a world class team, working together on one of the world's most exciting problems.","description_format":"text","description_chars":2187,"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":["Machine Learning","Predictive Analytics","Decision Intelligence"],"lifecycle":[{"event":"open","at":"2026-10-12T23:18:23Z"}],"visa":[],"liveness":{"score":4,"band":"cold","label":"Long shot","p_open":1,"p_active":0.128,"p_room":0.28,"age_days":248,"expected_fill_days":26,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-25T05:49:26Z"},"pay":null,"html_url":"https://alion.io/job/mantic-ai-engineer-researcher-llm-agent-focus","json_url":"https://alion.io/job/mantic-ai-engineer-researcher-llm-agent-focus.json","meta":{"generated_at":"2026-10-26T04:48:58Z","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":6437,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-27T00:00:00Z"}},"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":36340},"rest":"https://alion.io/mcp/rest/get_company?id=36340"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmantic-ai-engineer-researcher-llm-agent-focus"},{"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%2Fmantic-ai-engineer-researcher-llm-agent-focus"},{"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%2Fmantic-ai-engineer-researcher-llm-agent-focus"},{"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/mantic-ai-engineer-researcher-llm-agent-focus\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmantic-ai-engineer-researcher-llm-agent-focus"}]}
