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 launching perpetual futures and we're looking for a Senior Web Engineer to own the frontend of our perps product. You'll build the trading interfaces that traders will rely on every day: order entry, position management, real-time market data, and the full suite of UI that makes a great perps exchange feel fast, reliable, and intuitive.

This is a high-ownership role at the intersection of frontend product development, backend systems, performance, and reliability. We want someone who has shipped trading UIs before, understands the domain deeply, and can move fast without compromising quality.

What You'll Do

Own and ship complex trading UI features end-to-end — order books, position panels, trade history, funding rates, liquidation displays, and more — making thoughtful tradeoffs between speed, quality, and long-term maintainability

Work closely with backend engineers to design APIs, reason through real-time data flows, and build reliable trading experiences on top of complex exchange systems
