Lead Performance Web Engineer

About the Role

Polymarket is looking for a Lead Web Performance Engineer 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 (ie 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.

What You'll Do

• Own web performance end-to-end. 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.

• Set the technical direction. Define the architecture, standards, and tooling that govern how Polymarket approaches performance – caching strategy, rendering pipeline, bundle discipline, and edge delivery.

• Optimize the critical rendering path. Identify and eliminate bottlenecks in how pages load and render, including server-side rendering, hydration, code splitting, lazy loading, and asset delivery.
