Software Engineer (Web Infrastructure)

Join Notion's Web Infrastructure team as a Software Engineer. You'll focus on improving web client performance and development velocity, leading projects to enhance page loading and interaction latency. You'll also build tooling and frameworks to help product engineers create high-quality experiences. Ideal candidates have 8-10+ years of experience in web application development, strong collaboration skills, and a passion for building and optimizing software.

• Lead projects that reduce time to render a Notion page and time to interact with the page content across the app.
• Build tooling and frameworks that help product engineers build new products with a high quality experience.
• Define best practices and build developer tooling so that web engineers can develop product features more easily with confidence.
• You have around 8-10+ years of experience building and optimizing large web applications in React or similar frameworks
• Excellent collaboration and communication across platform and product teams, with a bias toward iterative, measurable impact
• 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
• 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
• Experience with modularizing large monorepos, reducing cyclic dependencies, and improving build times
• Familiarity with design systems and component performance, accessibility, and ergonomics
• If you’re excited about a role but your past experience doesn’t align perfectly with every bullet point listed in the job description, we still encourage you to apply. If you’re a builder at heart, share our company values, and enthusiastic about making software toolmaking ubiquitous, we want to hear from you
