Software Engineer, Web Infrastructure

Quick Facts

• Role: Junior Software Engineer (Web Infrastructure)

Description

You’ll help build and improve the client-side foundations behind Notion’s web experiences so product engineers can ship faster, more resilient, and more accessible features. Using browser tools and real-world data, you’ll investigate bottlenecks, improve performance tests and guardrails, and ship scoped improvements with measurable impact. You don’t need to be a performance expert on day one—strong fundamentals and a desire to learn by shipping useful work are key.

• Ship improvements to client loading, rendering, asset delivery, or caching; measure impact and check for regressions

• Partner with Web Infrastructure and product engineers to land changes safely across web clients

• Document learnings and share clear recommendations for performance tradeoffs

Requirements

• Solid programming fundamentals

• Some experience building software with JavaScript or TypeScript

• Familiarity with React or another component-based UI framework

• Curiosity about how browsers work and how code affects page load, rendering, and interaction responsiveness

• Thoughtful debugging approach (break down problems, gather evidence, ask for help)

• Clear, kind communication and interest in cross-team collaboration

Benefits

• Highly competitive cash compensation, equity, and benefits

• Estimated base salary range (SF/NYC): $150,000–$168,000 per year (may vary based on factors including location and experience)
