Anthropic is hiring a staff software engineer for the Web Platform team behind Claude.ai. The job is building shared infrastructure for the consumer product: reusable UI components and design-system abstractions, backend-for-frontend APIs for client applications, and build, deploy, testing and observability tooling. The posting asks for strong React and TypeScript skills, API design experience, and a record of building platforms other engineers depend on, with 5+ years preferred. Distinctive: the emphasis on developer velocity, and a hybrid policy expecting at least 25% in-office time, with visa sponsorship mentioned.
