WHO WE ARE Notion is the collaborative AI workspace where teams and agents think together https://www.youtube.com/watch?v=vkpYpWfEK5s. 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 WEB INFRASTRUCTURE TEAM: The Web Infrastructure team’s mission is to empower Notion engineers with web frameworks that are easy-to-use, performant, consistent and accessible. We own web foundations such as how client code is structured, how assets are served to users and how components are standardized and rendered to users. If we do our job well, Notion engineers should be able to build performant and beautiful product fast while Notion users enjoy a frictionless experience. 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. ABOUT THE ROLE: You’ll be a core engineer on the Web Infrastructure team, focusing on improving Notion’s web client performance and/or development velocity. You will lead projects that reduce time to render a Notion page and time to interact with the page content across the app. You will also build tooling and frameworks
