UI Software Engineer, Claude.ai Consumer Product

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
