Staff+ Software Engineer (Claude App Infrastructure)

About this role

• Claude App Infrastructure owns the reliability, experience, and agentic capabilities of claude.ai
• We are the platform team for Anthropic’s flagship consumer product — responsible for the serving architecture that keeps Claude available at scale, the conversation experience, and the infrastructure that lets every product team at Anthropic ship into claude.ai safely and fast
• When the product grows at hyper scale, we are the team that makes sure it feels the same — or better
• Beyond the foundation, we are building the agentic layer that turns claude.ai from a chat surface into an execution surface: task execution, personalization, browser use, server-side tools
• This is where the next generation of the product gets built — the primitives that let Claude act in the world, not just respond
• We believe reliability and velocity are the same problem, and our job is to build the systems that make both inevitable
• Design and build sandboxed compute environments where Claude can safely execute code, access tools, and interact with external services
• Build state management systems for long-running agent tasks—handling checkpoints, recovery, and resumption across failures
• Develop authentication and authorization frameworks for delegated access—enabling Claude to act on behalf of users securely
• Create observability and debugging tools for agent execution—understanding what Claude did, why, and how to make it better
• Partner closely with product and research teams to define what’s possible and ship it
