About the RolePolymarket 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.
This 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.
What You'll Do- Own the analytics on our largest makers, takers, and brokerages, and be the internal source of truth on how each relationship is performing
- Build the account-level view of every major counterparty - volume, flow composition, spread capture, fee and rebate economics, and how each has trended over time
- Monitor counterparty health and surface concentration risk, deteriorating engagement, or churn signals early enough for the team to act on them
- Analyze trading behavior to understand how each participant actually makes money on our platform, and whether the terms we have given them still make sense
- Support 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
- Quantify how institutional flow affects the broader market, including liquidity, spreads, and the experience of retail traders on the other side of it
- Work with analytics engineers to turn recurring relationship reporting into modeled datasets, so account reviews do not start from scratch every quarter
- Own documentation end-to-end - writing clearly and thoroughly enough that anyone on the team can pick up your analysis without friction
What We're Looking For- 7+ years in analytics, trading, or counterparty analysis, ideally at an exchange, trading venue, brokerage, or market making firm
- Expert SQL - you can work directly against order book and transaction-level data without supervision
- Deep understanding of how professional participants make money - spread capture, adverse selection, inventory risk, and the economics of providing liquidity
- Credibility in a technical conversation with a sophisticated counterparty - you can hold your own with a firm's own quants
- Commercial instinct - you can look at a relationship and articulate what it is worth to us and where the leverage sits
- Strong communication and discretion, including with sensitive counterparty information and in front of external partners
- Comfortable operating in a fast-moving environment where business logic changes frequently and you need to keep pace
- (Plus) Experience with institutional pricing, fee tiers, or rebate program design
- (Plus) Familiarity with on-chain data or blockchain analytics
- (Plus) Python or R for deeper statistical work on trading behavior
- (Plus) Experience in fintech, crypto, prediction markets, or other data-intensive financial products
Benefits- Competitive salary & equity
- Unlimited PTO
- Full Health, Vision, & Dental coverage
- 401k match
- Hardware setup: new MacBook Pro, big display, & accessories
