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.

A NOTE ON AI
You don’t need deep AI expertise for every role, but we do expect every Notino to be intellectually curious, drawn to tinkering and discovery, and excited to use AI as a real collaborator in their work. For some roles, AI fluency is a core requirement — when that’s the case, we'll say so explicitly in the qualifications. People who thrive here don’t treat AI as a novelty. They use it to think better, and make their work easier for others to build on.
