Responsibilities
Build and ship user-facing features for claude.ai's web experience, working closely with designers to bring detailed, polished interactions to life
Translate design intent into high-quality implementations — paying close attention to accessibility and the small details that add up to a great product feel
Build responsive applications that work well across devices and screen sizes, and actively care about the performance characteristics that shape how the product feels to use — latency, responsiveness, and reliability are first-class concerns, not afterthoughts
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
Work with the UI Platform team to consume shared components and tooling effectively, and flag gaps or pain points that would help the broader team move faster
Help maintain a high bar for code quality and consistency within the consumer product codebase
Qualification
Required
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
At least a Bachelor's degree in a related field or equivalent experience
Preferred
Accessibility best practices and building inclusive user interfaces
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.)
User research or usability testing, or a track record of incorporating user feedback into product decisions
Working on AI/ML products or in fast-moving consumer product environments
