Senior Data Scientist / Analyst, Finance

About the Role

Polymarket is looking for a Senior Financial Data Analyst to sit between our finance team and our data warehouse. You'll build and own the reporting layer that finance runs on, turning raw platform, on- and off-chain trading activity, and general ledger data into clean, reconciled financial reporting that people can trust without checking it by hand first.

The other half of the role is analytical. You'll be the person who understands how fees, incentives, and promotions actually flow through to revenue and retention, including what a promotion cost, what it returned, and whether the traders it brought in stayed. And you'll do it in a fast-moving environment where new products and incentive structures launch constantly.

What You'll Do

• Build and maintain the financial reporting layer in our data warehouse, including the modeled tables finance relies on for close, forecasting, and board reporting

• Work across the general ledger and platform data to reconcile what the business recorded against what actually happened on the platform

• Translate raw transaction, fee, and trading activity data into clean financial reports that need no manual cleanup before anyone can use them
