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 platform everything runs on. Design the orchestration layer that dispatches parallel research sessions, the data pipelines that feed them, the observability that monitors them, and the trading systems that act on what they find. Distributed systems meets autonomous AI infrastructure.\nYou might work on\nCompute scheduling and resource allocation across hundreds of agents\nStreaming data pipelines for real-time market ingestion\nAgent observability, experiment tracking, and reproducibility at scale\nLow-latency trading system design and optimization\nDetails\nStack: Python, Go, Kubernetes, streaming data, low-latency systems\n\nLocation: San Francisco (in-person)\n\nComp: Competitive salary + meaningful founding equity","description_format":"text","description_chars":1427,"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":"2026-08-28T03:04:54Z"}],"visa":[],"liveness":{"score":17,"band":"cold","label":"Long shot","p_open":1,"p_active":0.372,"p_room":0.45,"age_days":50,"expected_fill_days":30,"reasons":["conf:0","win:tail"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":true},"html_url":"https://alion.io/job/event-horizon-labs-founding-software-engineer","json_url":"https://alion.io/job/event-horizon-labs-founding-software-engineer.json","meta":{"generated_at":"2026-10-18T06:44:31Z","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":10007,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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-software-engineer"},{"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-software-engineer"},{"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-software-engineer"},{"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-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fevent-horizon-labs-founding-software-engineer"}]}
