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.

We're looking for someone who has operated at serious scale and knows what it takes to make a high-traffic mobile product feel instant and reliable for every user, everywhere. You'll come in with deep technical conviction and lay the foundation for a world-class mobile performance practice.

What You'll Do

Own mobile performance end-to-end. Take responsibility for startup time, rendering performance, and runtime efficiency across Polymarket's mobile platform, with measurable targets and a clear plan to hit them.

Set the technical direction. Define the architecture, standards, and tooling that govern how Polymarket approaches mobile performance: memory management, rendering pipelines, network efficiency, and background processing.

Optimize the critical path. Identify and eliminate bottlenecks in app startup, screen transitions, real-time data rendering, and network request handling across iOS and Android.
