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 Android Engineer to help build a world-class trading app on Android. Millions of users follow markets, track positions, and make trades on their phones — and the Android experience needs to match that level of engagement.
This is a high-ownership, high-influence role for someone who has operated at the staff level before and knows what it means to shape a platform, not just build on it. You'll set the technical direction for Android at Polymarket, raise the bar across the codebase, and help take a product that's already at scale to the next level.
