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. The Claude App Infrastructure team owns the reliability, experience, and agentic capabilities of claude.ai, serving the flagship consumer product. We are 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 make sure it feels the same or better. Beyond the foundation, we build 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.

- Experience with containers, sandboxing, or secure execution environments (e.g., gVisor, Firecracker, V8 isolates)
- Write clean, maintainable code in Python, Go, Rust, or a similar language
- Care about security, isolation, and building systems that fail safely
- Comfort with ambiguity and greenfield work where you help shape the architecture

- Low-level systems experience (Linux internals, eBPF, container runtimes)
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
