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

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
Drive network and caching strategy. Design efficient data fetching, caching, and synchronization architectures that minimize latency and keep the app responsive under varying network conditions
Build performance observability. Instrument real user monitoring, crash reporting, frame rate tracking, and synthetic testing so the team has continuous, actionable visibility into performance regressions
Set the performance bar across mobile engineering. Establish benchmarks, budgets, and standards that keep performance a first-class concern as the product and mobile team grow
