> Staff Software Engineer on the UI Platform team building accessible component primitives, automated testing infrastructure, and tooling that enables every product team to ship conformant experiences across Claude.ai surfaces. Requires 7+ years of experience with React/TypeScript and hands-on accessibility expertise.

## Job Description

## Responsibilities
- Shape the definition of how AI products should be accessible
- Design and publish accessible component primitives, libraries, and abstractions used across Anthropic's web and mobile surfaces
- Integrate accessibility into product workflows so standards are met by default rather than retroactively remediated
- Develop automated testing and agentic scanning infrastructure that catches accessibility regressions across surfaces
- Partner with product teams to resolve accessibility issues and prioritize the most impactful work
- Maintain documentation and tooling that make accessible engineering approachable

## Requirements
- 7+ years of software engineering experience, with significant time spent building accessible products, shared platforms, or developer tools that other engineers rely on
- Strong practical skills in modern web technologies (React, TypeScript or comparable frameworks)
- Hands-on familiarity with WCAG 2.2 AA, ARIA Authoring Practices, and HTML semantics
- Experience testing with assistive technology — screen readers (VoiceOver, NVDA, JAWS, TalkBack), keyboard-only navigation, magnification, voice control
- Care about developer experience and have a track record of building things that make other engineers more productive
- Solid instincts around accessibility, reliability, and quality—and enjoy operationalizing those instincts in production systems
- Thrive in fast-paced, collaborative environments and enjoy working closely with cross-functional partners

## Nice to Haves
- Building shared component libraries, design systems or reusable UI infrastructure
- Accessibility testing — automated, manual, or with assistive technology such as screen readers
- Streaming or real-time UI accessibility — live regions, dynamic content, queueing announcements under assistive tech
- Native platform accessibility on iOS, Android, macOS, or Windows
- CI/CD, build systems, and/or deployment automation
- Working with WCAG standards and producing or consuming Accessibility Conformance Reports
