Claude.ai is one of the most-used AI products worldwide, and the experience we build for our users directly shapes how people interact with AI every day. This product engineering role focuses on building the consumer web app—interfaces, interactions, and moments that turn Claude from a capable model into a product people genuinely enjoy using. The role involves working closely with designers and product managers to bring features from concept to shipped experience, obsessing over details such as latency, responsiveness, and reliability.

Requirements
Skills
- 5+ years of experience building consumer-facing web products, with a strong emphasis on UI quality and user experience
- Proficient in React, Next.js, and TypeScript, and have experience with Node.js on the backend side of the stack
- Genuinely care about the user experience — not just how something looks, but how fast it loads, how reliably it works, and how it feels across devices. You think about latency and responsiveness the same way you think about design
- Collaborate well with designers and product managers, and enjoy the iterative process of turning a design into something that works beautifully in the browser
- Comfortable working in a fast-moving environment where priorities shift and shipping quickly matters
- Pick up slack, even if it goes outside your job description
- Performance optimization for consumer web apps — profiling, reducing bundle size, improving rendering performance, and understanding where latency comes from end-to-end
- Designing and implementing responsive layouts that work well across screen sizes and devices
- Working on products with real-time or streaming interactions (chat interfaces, live updates, etc.)
- Working in fast-moving consumer product environments
Responsibilities
- Set technical direction for Claude.ai and its features
- Build and ship user-facing features for Claude.ai's web experience
- Own the quality bar for how the product looks and feels, treating latency, responsiveness, and reliability as first-class concerns rather than afterthoughts, and advocate for user experience and design considerations early in the process
- Collaborate tightly with product managers to understand user needs, shape feature scope, and make informed tradeoffs as you build
- Iterate quickly based on user feedback and internal testing, improving the experience on a continuous basis
