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 App Infrastructure owns the reliability, experience, and agentic capabilities of claude.ai. We're 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're the team that makes sure it feels the same or better. Beyond the foundation, we're building the agentic layer that turns claude.ai from a chat surface into an execution surface: task execution, personalization, browser use, and 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. Key responsibilities - 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, so Claude can act on behalf of users securely - Create observability and debugging tools for agent execution, so we understand 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 Minimum qualifications - Experience building distributed systems, infrastructure, or platform services at scale
