The biggest one right now is evaluation. Tutoring is multi-turn and adaptive, there is no verifiable reward signal, and existing benchmarks test single turns in toy scenarios. We are building the evaluations that make tutoring quality measurable, including simulated students realistic enough to test tutors against, and using them to improve our tutor in production.\nYou will own this work end to end: forming hypotheses, running experiments on real production sessions, and shipping findings into the product. You will work directly with one of the cofounders leading research, and with data that few groups have: full multimodal tutoring sessions at scale, with voice, whiteboard state, and student history.\nThis starts as a summer contract, with the intent to continue if it goes well. Full-time in SF is preferred; we are flexible on hours and location for the right person. We support publishing where we can, and we will tell you the constraints up front.","description_format":"text","description_chars":1053,"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":["Artificial Intelligence","Conversational AI","Education AI"],"lifecycle":[{"event":"open","at":"2026-09-06T06:58:52Z"}],"visa":[],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.19,"p_room":0.28,"age_days":124,"expected_fill_days":24,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-11-03T05:54:40Z"},"pay":{"stated_usd_annual":220000,"is_top_pay":true},"html_url":"https://alion.io/job/aristotle-research-scientist","json_url":"https://alion.io/job/aristotle-research-scientist.json","meta":{"generated_at":"2026-11-04T04:50:12Z","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":7458,"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":171283},"rest":"https://alion.io/mcp/rest/get_company?id=171283"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Faristotle-research-scientist"},{"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%2Faristotle-research-scientist"},{"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%2Faristotle-research-scientist"},{"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/aristotle-research-scientist\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Faristotle-research-scientist"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":435694}},{"tool":"search_jobs","arguments":{"company":"heyaristotle.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":435694},"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.
