Lead applied research on predictive models, dividing your time between inventing new modeling approaches and moving the strongest ones into live use. You will collaborate closely with senior technical and business leaders in an on-site team.\nWhat you'll do\n- Devote roughly 70% of your time to research, inventing and testing new model designs for risk prediction.\n- Mine sizable, imperfect in-house data to surface new features and predictive signals.\n- Investigate language-model and multimodal techniques that go beyond current tree-based approaches.\n- Devote roughly 30% of your time to production work, covering deployment, data sourcing needs and ongoing monitoring.\n- Work with a highly technical team and report to senior business and engineering leaders.\nRequirements\nWhat we're looking for\n- Roughly 5 to 10 years in applied machine learning research, where academic lab and doctoral work can count toward that time.\n- Hands-on background in an academic or university research lab.\n- An advanced degree in a quantitative discipline such as computer science, mathematics or physics, ideally from a highly ranked university.\n- Deep practical experience building predictive models with classical machine learning methods; a profile centered only on language models is not a fit.\n- A record of modeling complex, noisy real-world systems where many factors interact, such as robotics, physics or chemistry; finance experience is not needed.\n- Strong Python skills for both analysis and production machine learning.\n- Disciplined approach to testing models, including time-aware validation, probability calibration, decision threshold tuning, spotting data leakage and judging statistical significance.\n- Working knowledge of SQL, a dataframe library such as Pandas, and model explainability tooling.\n- Ability to work on-site five days a week.\nBonus points\n- Experience at leading AI research organizations.\n- Exposure to large language models.\nBenefits\nCompensation and benefits\n- Base salary: USD 250,000 to 400,000 per year\n- Equity\nLocation and work model\n- San Francisco, CA, United States\n- On-site, 5 days per week in office\n- Full-time","description_format":"text","description_chars":2294,"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"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-31T22:14:15Z"}],"visa":[{"country":"US","licensed_sponsor":false,"adverts_offering_sponsorship_24m":32,"sanctioned_now":false,"evidence":"Offered visa sponsorship in 32 of its adverts here in 24 months","filings_12m":0,"filings_prev_12m":0,"green_card_filings_12m":0,"median_offered_wage_usd":null,"route":null,"cap_exempt":false,"checked_at":"2026-11-09T07:32:21+00:00","sources":["Alion: sponsorship offered in the employer's own job adverts (24 months)"],"filings_for_role_12m":0}],"liveness":{"score":24,"band":"cold","label":"Long shot","p_open":1,"p_active":0.44,"p_room":0.55,"age_days":25,"expected_fill_days":22,"reasons":["conf:1","agency","velocity","win:tail","comp:brand"],"computed_at":"2026-11-10T06:52:35Z"},"pay":{"stated_usd_annual":400000,"is_top_pay":true},"html_url":"https://alion.io/job/raydar-machine-learning-researcher","json_url":"https://alion.io/job/raydar-machine-learning-researcher.json","meta":{"generated_at":"2026-11-10T09:33:51Z","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":22238,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-11T00:00:00Z"}},"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":4478753},"rest":"https://alion.io/mcp/rest/get_company?id=4478753"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fraydar-machine-learning-researcher"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Fraydar-machine-learning-researcher"},{"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%2Fraydar-machine-learning-researcher"},{"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/raydar-machine-learning-researcher\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fraydar-machine-learning-researcher"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3576834}},{"tool":"search_jobs","arguments":{"company":"raydar.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3576834},"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);
