## Job description

## ABOUT POLYMARKET

Polymarket is the world's largest prediction market platform. We enable individuals to express views on real-world events by trading on outcomes across politics, economics, sports, culture, and current affairs. Built as a peer-to-peer marketplace with no centralized "house," Polymarket aggregates diverse opinions into transparent, market-based probabilities that reflect collective expectations about the future.

We're growing fast — both in terms of volume ($21B traded in 2025) and adoption as an alternative news source. Our ambition is to become a ubiquitous beacon of truth in global media and we need your help adding fuel to the fire.

## 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.

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, alerting, and performance foundation that machinery stands on.

## WHAT YOU'LL DO

- Build and maintain agentic workflows that give every web engineer leverage: PR review agents, automated verification of fixes against production data, perf-regression detection and bisection, release gates
- Define the performance budget for Polymarket web and enforce it automatically — in CI, at the edge, and in RUM
- Instrument what matters: real-user metrics tied to the surfaces where users trade, not vanity lab scores
- Own the alert lifecycle end to end — from detector to dashboard to the engineer who acts on it; kill flaky signals and make green mean shippable
- Set the architecture bar for how the web team measures, ships, and verifies — and automate it so the bar holds at high velocity
- Own Core Web Vitals, real-user monitoring, bundle and rendering budgets, and caching and streaming strategy for Polymarket web
- Maintain one coherent, trustworthy picture of production web health across errors, traces, and RUM
- Own regression detection that fires when something real breaks — performance or correctness — and stays quiet otherwise
- Build and maintain the views the team and leadership actually use: release health, vitals, error budgets, funnel-critical surfaces
- Lead a small team from day one — set the direction, raise the bar, and multiply their output while staying hands-on

## WHAT WE'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
- Bias for ownership — this domain has no backstop
- Able to lead a small team while staying hands-on
- (Plus) Real-money or trading product experience — where latency and correctness both cost money
- (Plus) Cloudflare at depth: Workers, cache rules, edge telemetry
- (Plus) Experience running LLM-based code review or test generation at scale

## BENEFITS

- Competitive salary & equity
- Unlimited PTO
- Full Health, Vision, & Dental coverage
- 401k match
- Hardware setup: new MacBook Pro, big display, & accessories

## PAY TRANSPARENCY

Base salary range: $250,000 to $500,000 annually, plus equity and benefits.

This range reflects a good-faith estimate for this position. Experience levels vary widely within a title here, so please reach out even if your expectations fall outside it. We're always happy to chat.
