Software Engineer, Web Infrastructure

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.

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.

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.
