## Description

Who We Are Notion is the collaborative AI workspace where teams and agents think together . We're building one place where your knowledge, projects, meetings, and AI tools live side by side, so work is faster, clearer, and less fragmented. Millions of individuals, small teams, and large companies run their work on Notion. Notinos (our employees) are customer zero in bringing this future of work to life. We care about craft, building things that last, and the belief that great work is still fundamentally human. Our goal isn’t to ship the next feature. Each and every team of Notinos is working to set the standard for how humans work together in the AI era. From building a business’s system of record to making and managing AI agents to automating away the busy work, we care deeply about giving our customers more time for their life’s work. About the Role: Web Infrastructure builds the foundations behind Notion’s web clients so product engineers can ship fast, reliable, accessible experiences. As a junior engineer on the team, you’ll help make those experiences measurably faster and more resilient. You’ll investigate performance bottlenecks, improve how the client loads and responds, and help build tools that catch regressions earlier. You don’t need to arrive as a performance expert; we’re looking for strong fundamentals, curiosity, and a desire to learn by shipping useful work. This role can be based in either San Francisco or New York City. We work from our offices on Mondays, Tuesdays and Thursdays (our Anchor Days) because we do our best thinking and building together in person. We’re looking for someone who’s excited to work alongside the team during those days. What You'll Achieve: Use browser tools and real-world data to investigate page-load and interaction bottlenecks, then turn findings into focused improvements. Help build or improve performance tests, dashboards, and guardrails that make regressions easier to catch during development and rollout. Ship scoped improvements to client loading, rendering, asset delivery, or caching, measuring their impact and checking for regressions. Partner with Web Infrastructure and product engineers to land changes safely across Notion’s web clients. Document what you learn and share clear recommendations so teams can make better performance tradeoffs. Skills You'll Need to Bring: Solid programming fundamentals and some experience building software with JavaScript or TypeScript; familiarity with React or another component-based UI framework is helpful. Curiosity about how browsers work and how code affects page load, rendering, and interaction responsiveness. A thoughtful debugging approach: you can break a problem down, gather evidence, and ask for help when you’re stuck. Clear, kind communication and an interest in collaborating across teams. Intellectual curiosity about AI-enabled engineering tools; you use them thoughtfully and review their output critically. Experience with performance profiling, browser developer tools, React profiling, bundlers, code splitting, service workers, asset caching, or performance testing is a plus—not a prerequisite. We welcome candidates who are excited about the work even if they don’t match every bullet. Notion is committed to providing highly competitive cash compensation, equity, and benefits. The compensation offered for this role will be based on multiple factors such as location, the role’s scope and complexity, and the candidate’s experience and expertise, and may vary from the range provided below. For roles based in San Francisco or New York City, the estimated base salary range for this role is $150,000 - $168,000 per year. By clicking “Submit Application”, I understand and agree that Notion and its affiliates and subsidiaries will collect and process my information in accordance with Notion’s Global Recruiting Privacy Policy and NYLL 144 . #LI-Onsite A Note on AI You don’t need deep AI expertise for every role, but we do expect every
