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 Staff iOS Engineer to help build our iOS product as we invest seriously in mobile. This is a high-ownership role for someone who understands what it takes to build a great trading or wagering experience on mobile – the performance requirements, the real-time data challenges, the UI patterns that make fast-moving information feel intuitive rather than overwhelming.

You'll work closely with product, design, and engineering leadership to deliver a high-quality iOS experience and help raise the bar across the mobile codebase. The right person has been in this world before: they know what a great trading or sportsbook app feels like from the inside, and they want to build something better.

What You'll Do

Own the iOS product. Take end-to-end ownership of Polymarket's iOS experience, from technical architecture and performance to product quality and release discipline.

Set the technical direction. Make and own architectural decisions for the iOS platform, ensuring the codebase is built to scale and maintained with rigor as the product grows.

Build for real-time. Design and implement experiences that handle live market data, fast-moving prices, and real-time order state in a way that feels fast and reliable to users.
