Details

Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. The Claude.ai consumer product team 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 focused on building polished, high-quality web experiences and collaborating closely with designers and product managers to ship features that feel fast, reliable, and accessible.

Responsibilities

Build and ship user-facing features for claude.ai's web experience, translating design intent into high-quality implementations
Focus on accessibility, performance (latency, responsiveness, reliability), and cross-device responsive behavior
Collaborate tightly with designers and product managers to shape feature scope and iterate quickly based on user feedback and testing
Consume shared components and tooling from the UI Platform team and surface gaps or pain points
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 strong emphasis on UI quality and user experience
Proficient in React, Next.js, and TypeScript; experience with Node.js on the backend side of the stack
Strong attention to accessibility, performance characteristics, and responsive design
Comfortable working in a fast-moving environment and collaborating closely with designers and product managers
Product-first engineering mindset: care about how things feel, load, and behave in real-world use
Education: at least a Bachelor's degree in a related field or equivalent experience

Strong candidates may also have experience with

Accessibility best practices and building inclusive user interfaces
Performance optimization for consumer web apps (profiling, reducing bundle size, improving rendering performance, end-to-end latency)
Designing and implementing responsive layouts across screen sizes and devices
Working on products with real-time or streaming interactions (chat interfaces, live updates)
User research or usability testing and incorporating feedback into product decisions
Working on AI/ML products or in fast-moving consumer product environments
