Job description

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 already at scale to the next level.

What You'll Do

• Set the technical direction for Android at Polymarket, making and owning architectural decisions that the team builds around
• 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 under real trading conditions and meet a high bar for feel and reliability
• Own CI/CD pipelines and Gradle configuration, keeping the build fast and the release process reliable as the team and product grow
• Build and maintain integrations across WebSockets, gRPC, and streaming data to power the live market features traders depend on
• Operate as a technical leader across a distributed team: communicate clearly, make decisions without hand-holding, and raise the engineering bar through code reviews and strong engineering standards
• Actively incorporate AI tools into your development workflow to move faster and maintain a high output bar
• Identify and address gaps in Android architecture and engineering practices before they become problems at scale

What We're Looking For

• Significant Android engineering experience, with a track record of owning and shaping Android platforms at scale, not just contributing to them
• Strong, current expertise in Kotlin with the ability to speak concretely to tradeoffs and make architectural calls with confidence
• Deep experience building production UI with Jetpack Compose and a high bar for performance and polish
• Experience owning CI/CD pipelines and Gradle build configuration end-to-end
• Solid understanding of modern Android architecture with the judgment to evolve it as the product scales
• A track record of technical leadership: you've influenced how an engineering team works, not just what it ships
• Active use of AI tools in your development workflow, not occasionally, but as a real part of how you work
• (Plus) Experience integrating payments on Android
• (Plus) Experience with WebSockets, gRPC, or other real‑time data patterns on mobile
• (Plus) Familiarity with cross-platform shared-code architectures
• (Plus) iOS or Swift experience
• (Plus) Background at a larger, more mature engineering organization where you saw and shaped practices as the company grew

Benefits

• Competitive salary & equity
• Unlimited PTO
• Full Health, Vision, & Dental coverage
• 401k match
• Hardware setup: new MacBook Pro, big display, & accessories
