## About the role

Polymarket is looking for a Lead Mobile Performance Engineer to own the speed, efficiency, and responsiveness of our mobile platform. You'll set the direction for mobile performance at Polymarket, establish the standards and systems that keep the product fast at scale, and shape how Polymarket thinks about performance as a discipline across iOS and Android.

## What they're looking for

- Deep experience in mobile performance engineering at significant scale, across iOS, Android, or both
- Strong expertise across the mobile performance stack: rendering, memory management, network optimization, background processing, and app startup
- Proficiency in Swift and/or Kotlin, with a strong understanding of how the underlying mobile runtimes, rendering systems, and OS scheduling interact
- Experience with real user monitoring, frame rate profiling, and building observability systems that surface regressions before users feel them
- A rigorous, measurement-driven approach — you don't guess at performance problems, you profile, instrument, and prove them
- Technical leadership experience — you've set direction, raised the bar across a codebase, and influenced how a broader engineering team thinks about performance
