About Polymarket

Polymarket is the world’s largest prediction market platform. 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.

We're growing fast – both in terms of volume ($21B traded in 2025) 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.

About the Role

Polymarket is looking for a pragmatic full-stack engineer to join our US Exchange team. You'll build the critical internal systems that power our CFTC-regulated exchange operations—from payment reconciliation and transaction processing to operational dashboards and compliance tooling.

This is a high-impact role where you'll work directly with operations teams, build systems that handle real money at scale, and help establish the technical foundation for our growing US exchange business. If you enjoy solving complex problems in fintech, building tools that people actually use every day, and shipping code that matters, this role is for you.

What You’ll Do

Build tools for US exchange operations. Create systems that help control desk operators, supervisors, and compliance teams manage high-volume payment processing and reconciliation workflows.

Ship production features regularly. Launch improvements and fixes frequently in a fast-paced, regulated environment where reliability matters.

Work across the full stack. Build frontend interfaces for operational dashboards and backend APIs for transaction processing, reconciliation, and payment provider integrations and other control desk operations.
