Staff Software Engineer, Claude.ai

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.

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:

• Set technical direction for Claude.ai and its features
• Build and ship user-facing features for Claude.ai's web experience
• Own the quality bar for how the product looks and feels, treating latency, responsiveness, and reliability as first-class concerns rather than afterthoughts, and advocate for user experience and design considerations early in the process
• 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

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 responsivene
