We enable individuals to express views on real-world events by trading on outcomes across politics, economics, sports, culture, and current affairs. Built as a peer-to-peer marketplace with no centralized \"house,\" Polymarket aggregates diverse opinions into transparent, market-based probabilities that reflect collective expectations about the future.\nWe're growing fast, both in terms of volume ($115B traded to date) and adoption as an alternative news source. Our ambition is to become a ubiquitous beacon of truth in global media and we need your help adding fuel to the fire.\nAbout the Role\nPolymarket is looking for a Senior Data Scientist / Analyst to own the analytics behind our institutional relationships - the market makers, large takers, and brokerages that account for a disproportionate share of platform volume. You'll be the person who understands each of these counterparties in depth: how they trade, how they make money with us, and whether the relationship is getting healthier or weaker.\nThis is a role for someone comfortable on both sides of the conversation - rigorous enough to analyze flow at the order level, and commercial enough to sit in a partner review and explain what the numbers mean for the terms of the relationship. And you'll do it in a fast-moving environment where the institutional side of the business is being built as you go.\nWhat You'll Do\nOwn the analytics on our largest makers, takers, and brokerages, and be the internal source of truth on how each relationship is performing\n\nBuild the account-level view of every major counterparty - volume, flow composition, spread capture, fee and rebate economics, and how each has trended over time\n\nMonitor counterparty health and surface concentration risk, deteriorating engagement, or churn signals early enough for the team to act on them\n\nAnalyze trading behavior to understand how each participant actually makes money on our platform, and whether the terms we have given them still make sense\n\nSupport the institutional team through reviews and negotiations with the analysis behind them - what a counterparty is worth, what they are asking for, and what we should be willing to give\n\nQuantify how institutional flow affects the broader market, including liquidity, spreads, and the experience of retail traders on the other side of it\n\nWork with analytics engineers to turn recurring relationship reporting into modeled datasets, so account reviews do not start from scratch every quarter\n\nOwn documentation end-to-end - writing clearly and thoroughly enough that anyone on the team can pick up your analysis without friction\n\nWhat We're Looking For\n7+ years in analytics, trading, or counterparty analysis, ideally at an exchange, trading venue, brokerage, or market making firm\n\nExpert SQL - you can work directly against order book and transaction-level data without supervision\n\nDeep understanding of how professional participants make money - spread capture, adverse selection, inventory risk, and the economics of providing liquidity\n\nCredibility in a technical conversation with a sophisticated counterparty - you can hold your own with a firm's own quants\n\nCommercial instinct - you can look at a relationship and articulate what it is worth to us and where the leverage sits\n\nStrong communication and discretion, including with sensitive counterparty information and in front of external partners\n\nComfortable operating in a fast-moving environment where business logic changes frequently and you need to keep pace\n\n(Plus) Experience with institutional pricing, fee tiers, or rebate program design\n\n(Plus) Familiarity with on-chain data or blockchain analytics\n\n(Plus) Python or R for deeper statistical work on trading behavior\n\n(Plus) Experience in fintech, crypto, prediction markets, or other data-intensive financial products\n\nBenefits\nCompetitive salary & equity\n\nUnlimited PTO\n\nFull Health, Vision, & Dental coverage\n\n401k match\n\nHardware setup: new MacBook Pro, big display, & accessories\n\nPay Transparency\nBase salary range: $200,000 to $300,000 annually, plus equity and benefits.\nThis range reflects a good-faith estimate for this position. Experience levels vary widely within a title here, so please reach out even if your expectations fall outside it. We're always happy to chat.","description_format":"text","description_chars":4381,"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":["401k plan","Apple Macbook","Equity","Unlimited PTO"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Blockchain & Crypto","Web3 & dApps","iGaming & Gambling"],"lifecycle":[{"event":"open","at":"2026-08-12T15:28:43Z"}],"visa":[],"liveness":{"score":33,"band":"fade","label":"Fading","p_open":1,"p_active":0.74,"p_room":0.44,"age_days":71,"expected_fill_days":54,"reasons":["conf:2","velocity","win:tail","crowd:"],"computed_at":"2026-10-23T05:54:15Z"},"pay":{"stated_usd_annual":300000,"is_top_pay":true},"html_url":"https://alion.io/job/polymarket-senior-data-scientist-analyst-institutional","json_url":"https://alion.io/job/polymarket-senior-data-scientist-analyst-institutional.json","meta":{"generated_at":"2026-10-23T21:15:46Z","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":3148,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-24T00:00:00Z"}},"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":604},"rest":"https://alion.io/mcp/rest/get_company?id=604"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fpolymarket-senior-data-scientist-analyst-institutional"},{"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%2Fpolymarket-senior-data-scientist-analyst-institutional"},{"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%2Fpolymarket-senior-data-scientist-analyst-institutional"},{"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/polymarket-senior-data-scientist-analyst-institutional\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fpolymarket-senior-data-scientist-analyst-institutional"}]}
