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 Senior 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 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 raise the bar across the Android codebase and help take a product that's already at scale to the next level.
WHAT YOU'LL DO
- Build and own Android features spanning payments flows, real-time market data, and core UI with full accountability from design handoff through to production
- Implement polished, performant interfaces with Jetpack Compose that hold up
