## Description

Polymarket 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
