Senior Payment Risk Analyst

About the Role

Polymarket operates as a CFTC-regulated prediction market exchange, which means money movement is not a back-office function. It is core infrastructure. Deposits, withdrawals, and settlement payouts happen at high volume and accelerate dramatically around major real-world events. The Senior Payment Risk Analyst role exists to own the risk posture around all of it: how money gets onto the platform, how it moves across it, and how it leaves.

This is a senior / contributor role on the Payments Risk team within the US Exchange. You will sit at the intersection of fraud operations, payment rail mechanics, and regulatory compliance. Day to day, that means investigating live cases, monitoring transaction data, writing and tuning fraud rules, and maintaining the banking, card network, and processor relationships that depend on us keeping our house in order. You will work closely with Compliance, Engineering, Legal and InfoSec. When you identify a control gap, you are expected to close it, not just document it.

The challenge here is real. Payment volumes can spike by an order of magnitude in hours when a major market goes live. Fraud patterns shift fast. Regulatory expectations are high and still evolving. If you want a role where the risk environment is stable and well-understood, this is not it. If you want to build the payment risk function at a company that is redefining how people engage with information and markets, read on.

What You'll Do

• Investigate live payment fraud cases across deposits, withdrawals, and settlement payouts, making timely decisions on holds, reversals, and account actions.

• Monitor transaction data for anomalies tied to high-volume market events, distinguishing normal volume spikes from genuine abuse signals.
