UI Software Engineer (Claude.ai Consumer Product)

About this role

• We’re looking for a talented engineer to join the team that builds the consumer web app — the interfaces, interactions, and moments that turn Claude from a capable model into a product people genuinely enjoy using
• This is a product engineering role first and foremost
• You’ll work closely with designers and product managers to bring features from concept to shipped experience, obsessing over the details that make the difference: how something feels when you first land on it, how smoothly a new interaction flows, how an interface holds up under real-world use
• Great UX isn’t just about how something looks — it’s about how fast it feels, how reliably it works, and how well it adapts to the device and context someone is using it on
• You won’t need to be building backend infrastructure or platform tooling — your focus is on crafting the best possible experience for the people using Claude.ai on the web
• 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
