The orchestrator, the agents, the compounding knowledge base are already discovering profitable strategies and scaling with each new model release. These are founding roles with competitive salary and equity.\nThe next breakthrough isn't a better model - it's infrastructure for autonomous problem-solving. Markets are the first domain because feedback is immediate, signal is verifiable, and outcomes are directly monetizable. What we're building doesn't stop at markets.\nTeam from Citadel, Jump Trading, Stanford, Caltech, Berkeley.\nYou build the system that generates alpha. Design the research orchestration layer - what to explore, how to evaluate it, what to remember - and train the models that power it. You'll work at the intersection of ML systems and quantitative finance, closing the loop from hypothesis to P&L.\nYou might work on\nResearch orchestration optimized for maximum exploration velocity\nTraining small transformers on proprietary data for signal prediction\nBacktesting frameworks with regime-aware evaluation\nKnowledge systems that compound across thousands of sessions\nDetails\nStack: Python, PyTorch, proprietary feature discovery, model fitting and backtesting infra\n\nLocation: San Francisco (in-person)\n\nComp: Competitive salary + meaningful founding equity","description_format":"text","description_chars":1444,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Machine Learning","Financial AI"],"lifecycle":[{"event":"open","at":"2026-08-28T05:44:54Z"}],"visa":[],"liveness":{"score":18,"band":"cold","label":"Long shot","p_open":1,"p_active":0.404,"p_room":0.45,"age_days":54,"expected_fill_days":30,"reasons":["conf:2","win:tail"],"computed_at":"2026-10-21T05:46:15Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":true},"html_url":"https://alion.io/job/event-horizon-labs-founding-research-engineer-2","json_url":"https://alion.io/job/event-horizon-labs-founding-research-engineer-2.json","meta":{"generated_at":"2026-10-21T13:48:29Z","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":19605,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"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":9360},"rest":"https://alion.io/mcp/rest/get_company?id=9360"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fevent-horizon-labs-founding-research-engineer-2"},{"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%2Fevent-horizon-labs-founding-research-engineer-2"},{"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%2Fevent-horizon-labs-founding-research-engineer-2"},{"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/event-horizon-labs-founding-research-engineer-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fevent-horizon-labs-founding-research-engineer-2"}]}
