Software Engineer, Web Infrastructure

Who We Are Notion is the collaborative AI workspace where teams and agents think together. We're building one place where your knowledge, projects, meetings, and AI tools live side by side, so work feels 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, humanity, and building things that last — not just shipping the next feature, but setting a standard for how modern teams with humans and agents working together think and execute. 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 by making the components and other parts 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. We hire talented and passionate people from a variety of backgrounds because we want our global employee base to represent the wide diversity of our customers. 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. Notion is committed to providing highly competitive cash compensation, equity, and benefits. The compensation offered for this role will be based on multiple factors such as location, the role’s scope and complexity, and the candidate’s experience and expertise, and may vary from the range provided below. For roles based in San Francisco or New York City, the estimated base salary range for this role is $260k - $330k per year. 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 make it explicit in the qualifications. People who thrive here don’t treat AI as a novelty. They use it to think better, move faster, and build more creatively. Equal Opportunity & Accommodations Notion is proud to be an equal‑opportunity employer.
