About the role
Polymarket's web team ships to production many times a day across our Next.js apps. This role owns the systems that make that velocity safe: the AI tooling, observability, alerting, and performance discipline that tell us — with evidence, automatically — that the site is fast and correct after every ship.
What they're looking for
- Expert in web performance — you can take a slow page and make it fast, and prove the win with real-user data, not lab runs
- Experience shipping for real users at scale — you've owned a production web app with a large, active user base where a regression hit thousands of users within minutes and monitoring was how you knew
- Deep Next.js experience: App Router, React Server Components, streaming/PPR, caching layers, hydration cost
- Experience building AI/agentic developer tooling — or serious automation — that a team relied on daily, with opinions about where agents genuinely help vs. where they add noise
- Experience owning observability and alerting for a high-traffic production product: instrumentation, dashboards, on-call signal quality
- Strong systems thinking across the full path: CDN/edge caching, browser internals, measurement bias, backend latency's effect on the frontend

This is a hands-on architect role with a clear foundation to build on. The center of gravity is agentic tooling — building the AI-driven review, QA, verification, and release machinery the web team leans on daily. The rest is the observability,...
