## Job Description

## 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
- 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

## Requirements
- 5+ years of experience building consumer-facing web products, with a strong emphasis on UI quality and user experience
- Proficiency in React, Next.js, and TypeScript
- Experience with Node.js on the backend side of the stack
- Genuine 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
- Comfort working in a fast-moving environment where priorities shift and shipping quickly matters
- Willingness to pick up slack, even if it goes outside your job description

## Nice to Haves
- Experience with 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
- Experience 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
- Experience working on AI/ML products or in fast-moving consumer product environments

## Compensation & Benefits
- Annual Salary: $320,000–$405,000 USD
- Location-based hybrid policy: Staff expected in office at least 25% of the time
