What does a Web Performance Engineer do?

A Web Performance Engineer specializes in optimizing the speed, responsiveness, and overall performance of websites and web applications. They analyze site metrics, identify bottlenecks, and implement solutions such as code optimizations, efficient asset loading, and server-side improvements. Their goal is to ensure users have a fast and seamless experience, which can positively impact user engagement and search rankings. Web Performance Engineers often work closely with developers, designers, and DevOps teams to address performance issues throughout the development lifecycle.

What are some common challenges Web Performance Engineers face when optimizing large-scale websites?

Web Performance Engineers often encounter challenges such as balancing performance improvements with maintaining site functionality, addressing bottlenecks in both front-end and back-end systems, and ensuring that optimizations do not negatively impact user experience. Working with legacy codebases or third-party scripts can further complicate the process, requiring creative solutions and strong collaboration with development, QA, and DevOps teams. Staying current with evolving web technologies and performance measurement tools is also essential to continuously drive improvements.

What is the difference between Web Performance Engineer vs Web Developer?

AspectWeb Performance EngineerWeb Developer
Primary FocusOptimizing website speed and performanceBuilding and maintaining website features and functionality
Skills & CertificationsPerformance testing, web optimization, coding skills, certifications like Google Analytics or LighthouseProgramming languages, front-end/back-end development, frameworks
Work EnvironmentPerformance testing labs, development teams, QA environmentsDevelopment teams, project management, design teams
Industry UsageTech, e-commerce, media, any online service prioritizing speedAll industries with web presence, including tech, retail, finance

While both roles work closely within web development teams, Web Performance Engineers specialize in optimizing website speed and efficiency, whereas Web Developers focus on creating and maintaining website features. Understanding these differences helps organizations assign the right talent for performance versus development tasks.

What are the key skills and qualifications needed to thrive as a Web Performance Engineer, and why are they important?

To thrive as a Web Performance Engineer, you need expertise in front-end and back-end web technologies, knowledge of web performance optimization strategies, and a relevant degree in computer science or a related field. Familiarity with tools such as Lighthouse, WebPageTest, Chrome DevTools, and content delivery networks (CDNs) is crucial, and certifications like Google Mobile Web Specialist can be advantageous. Strong problem-solving skills, attention to detail, and effective communication help you collaborate with development teams and present findings clearly. These skills and qualities are essential to ensure websites run efficiently, deliver excellent user experiences, and meet business objectives.

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 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.
  • 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.
What We're Looking For
  • 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
  • (Plus) Experience with Next.js, React, and modern SSR/SSG rendering strategies at scale
  • (Plus) Familiarity with edge computing, worker runtimes, or CDN-level programmability
Benefits
  • Competitive salary & equity
  • Unlimited PTO
  • Full Health, Vision, & Dental coverage
  • 401k match
  • Hardware setup: new MacBook Pro, big display, & accessories
