We trade all asset classes globally, with a focus on options.\nWe are made up of developers, researchers, and traders, although the roles are quite fluid. Everyone on the team writes and ships code.\nOur primary office is in New York. We also have people in Zurich, Singapore, Hong Kong, London, and Austin.\nThe Role\nThe Quantitative Developer role on our team has evolved substantially in light of recent AI developments.\nDevelopers now focus on the larger architectural problems: the platforms and core tools that power the team's workflows, and their speed, reliability, and safety.\nDevelopers also maintain our live trading systems and work with our traders throughout the trading day.\nHow We Work\nLike a startup. We do not have a slow-moving ticket queue or product managers. We resolve problems quickly and aim to ship the same day.\nAI-native. AI agents are central to how we build. The value of the developer is directing agents to work on the right tasks and holding their output to a high standard.\nImmediate ownership. The team is lean. You will very quickly lead projects which directly impact trading.\nIn office. We work from our Hudson Yards office every day. Traders, researchers and developers all sit right next to each other.\nOur Stack (any is a plus)\nPython (Polars), Linux\nRedis, Postgres, ClickHouse, Iceberg, Airflow\nTypeScript / React\nRust, C++\nPreferred Experience\n3+ years of experience as a software engineer\nExperience in trading or finance\nVery strong in Python\nA software engineer first. This is not an options pricing or modeling role.\nAI-first mentality\nMillennium pays a total compensation package which includes a base salary, discretionary performance bonus, and a comprehensive benefits package. The estimated base salary range for this position is $100,000 to $200,000, which is specific to New York and may change in the future. When finalizing an offer, we take into consideration an individual’s experience level and the qualifications they bring to the role to formulate a competitive total compensation package.","description_format":"text","description_chars":2200,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Hedge Funds & Alternative Investments"],"lifecycle":[{"event":"open","at":"2026-11-12T01:55:09Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":1,"expected_fill_days":90,"reasons":["conf:4","win:early","comp:brand"],"computed_at":"2026-11-12T05:56:27Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":true},"html_url":"https://alion.io/job/millennium-management-quantitative-developer-5","json_url":"https://alion.io/job/millennium-management-quantitative-developer-5.json","meta":{"generated_at":"2026-11-12T05:56:27Z","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":11799,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-13T00:00:00Z"}},"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":704283},"rest":"https://alion.io/mcp/rest/get_company?id=704283"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmillennium-management-quantitative-developer-5"},{"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%2Fmillennium-management-quantitative-developer-5"},{"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%2Fmillennium-management-quantitative-developer-5"},{"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/millennium-management-quantitative-developer-5\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmillennium-management-quantitative-developer-5"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4128640}},{"tool":"search_jobs","arguments":{"company":"mlp.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4128640},"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.
