Job description
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 Anthropic's flagship consumer product, spanning web, mobile, desktop, and browser extensions—and it's growing fast. The UI Platform team owns the foundational layer that makes Claude usable for every person who relies on it: the shared components, primitives, automated testing, and tooling that let every other product team at Anthropic ship accessible experiences quickly, reliably, and with confidence. As a Software Engineer on this team, you'll be hands-on designing and shipping accessible shared components and design-system-level abstractions, building the automated accessibility testing layer that catches regressions across surfaces, and improving the build, deploy, and testing systems that keep Claude.ai conformant across surfaces. Your work will directly shape how fast teams across Anthropic can ship accessibly—and how reliable their experiences are for users who rely on assistive technology. As we innovate new Claude products, we have an opportunity to lead the field in designing them in an accessible way. This is a great fit if you care deeply about accessibility and want your engineering work to have outsized leverage: instead of shipping one feature, you're building the tools and systems that make every feature accessible. 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 You may be a good fit if you Have 7+ years of software engineering experience, with significant time spent building accessible products, shared platforms, or developer tools that other engineers rely on Have strong practical skills in modern web technologies (React, TypeScript or comparable frameworks) Have hands-on familiarity with WCAG 2.2 AA, ARIA Authoring Practices, and HTML semantics Have 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 Have 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 Pick up slack, even if it goes outside your job description Strong candidates may also have experience with 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, mac
