Polymarket is looking for a Lead Web Engineer, Performance to own the speed, efficiency, and scalability of our web platform. You'll set the direction for web 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
We're looking for someone who has operated at serious scale (billions of page loads) and knows what it takes to make a high-traffic web product fast for every user, everywhere. You'll come in with deep technical conviction and lay the foundation for a world-class web performance practice
Take responsibility for load times, rendering performance, and runtime efficiency across Polymarket's web platform, with measurable targets and a clear plan to hit them
Define the architecture, standards, and tooling that govern how Polymarket approaches performance — caching strategy, rendering pipeline, bundle discipline, and edge delivery
Identify and eliminate bottlenecks in how pages load and render, including server-side rendering, hydration, code splitting, lazy loading, and asset delivery
Design and maintain caching architectures at every layer (browser, CDN, and edge) to minimize latency and maximize cache hit rates at scale
Instrument real user monitoring, Core Web Vitals tracking, and synthetic testing so the team has continuous, actionable visibility into performance regressions
Establish benchmarks, budgets, and standards that keep performance a first-class concern as the product and engineering team grow
