Responsibilities
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
Drive caching and CDN strategy. Design and maintain caching architectures at every layer (browser, CDN, and edge) to minimize latency and maximize cache hit rates at scale
Build performance observability. Instrument real user monitoring, Core Web Vitals tracking, and synthetic testing so the team has continuous, actionable visibility into performance regressions
Set the performance bar across engineering. Establish benchmarks, budgets, and standards that keep performance a first-class concern as the product and engineering team grow
Qualification
Required
Deep experience in web performance engineering at significant scale – you've worked on systems serving billions of page loads and know what breaks at that level
Strong expertise across the web performance stack: rendering, caching, CDN configuration, bundle optimization, and Core Web Vitals
Proficiency in JavaScript and TypeScript, with a strong understanding of how browser engines, the V8 runtime, and the network layer interact
Experience with real user monitoring, synthetic performance testing, 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
Preferred
Experience with Next.js, React, and modern SSR/SSG rendering strategies at scale
Familiarity with edge computing, worker runtimes, or CDN-level programmability
