Staff UI Software Engineer, Claude.ai Consumer Product at Anthropic — task breakdown

About Anthropic Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems. About the role: Claude.ai is one of the most-used AI products in the world, and the experience we build for our users directly shapes how people interact with AI every day. 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. The pace is fast, the product is evolving quickly, and the opportunity to have a visible, direct impact on how millions of people use AI is real. If you love building consumer products and care about getting the details right, this could be a great fit. 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 You may be a good fit if you: Have 5+ years of experience building consumer-facing web products, with a strong emphasis on UI quality and user experience Are 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 Are 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 Strong candidates may also have experience with: A
