Staff Android Engineer
About This 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 trade 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 an already-scaled product to the next level.
What You'll Be Doing
Set the technical direction for Android at Polymarket, making and owning architectural decisions 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 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 live market features
Operate as a technical leader across a distributed team: communicate clearly, make decisions independently, and raise engineering standards through code reviews
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: influencing how an engineering team works, not just what it ships
Active use of AI tools as a real part of your development workflow
Bonus Points
Experience integrating payments on Android
Experience with WebSockets, gRPC, or other real-time data patterns on mobile
Familiarity with cross-platform shared-code architectures
iOS or Swift experience
Background at a larger, more mature engineering organization where you saw and shaped practices as the company grew
Why Join Us
Competitive salary and equity, with a base salary range of $250,000 to $500,000 plus equity and benefits
Unlimited PTO
Full health, vision, and dental coverage
401k match
