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 world-class infrastructure engineer to join our DeFi team and help scale the systems that power our trading platform. You'll be responsible for designing, building, and maintaining the backbone of our engineering platform: from developer workflows and CI/CD pipelines to core infrastructure supporting the high-performance APIs, data services, and real-time trading systems at the heart of what we do. You'll have the autonomy to make big technical decisions, drive system architecture, and implement solutions that balance speed, reliability, and long-term maintainability in one of the most demanding technical environments in crypto.

What You'll Do

Build and automate development workflows. Design and maintain infrastructure that standardizes how we develop, version, test, and deploy software across environments.

Architect scalable systems. Make thoughtful architectural decisions and tradeoffs, balancing risk, performance, cost, and maintainability across the DeFi trading stack.

Power high-performance trading services. Contribute to infrastructure supporting real-time APIs, low-latency data feeds, and the exchange systems that underpin Polymarket's markets.
