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.
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 that help product engineers build new products with a high quality experience.
What You'll Achieve:- Improve Users Page Loading experience through modularizing client codebase, lazy loading or caching relevant assets for the users.
- Improve Interaction Latency through make the components and other part of codebase more lightweight and efficient.
- Define best practices and build developer tooling so that web engineers can develop product features more easily with confidence.
Skills You'll Need to Bring:- You have around 8-10+ years of experience building and optimizing large web applications in React or similar frameworks.
- Proven track record improving real-user performance metrics at scale, from page load to post-load interactivity.
- Strength in modern bundling and build tooling such as Webpack and performance profiling.
- Strong systems thinking and ability to design paved-road abstractions, guardrails, and tooling for many teams.
- Excellent collaboration and communication across platform and product teams, with a bias toward iterative, measurable impact.
- You don't need to be an AI expert, but you're curious and willing to adopt AI tools to work smarter and deliver better results.
Nice to Haves:- Experience with modularizing large monorepos, reducing cyclic dependencies, and improving build times.
- Familiarity with design systems and component performance, accessibility, and ergonomics.
