The Claude App Infrastructure team builds and maintains the platform that powers Claude.ai, focusing on reliability, scalability, and agentic capabilities. The role involves designing sandboxed compute environments, state management, authentication frameworks, observability tools, and collaborating closely with product and research teams to ship features.

Requirements

Skills

  • Experience building distributed systems, infrastructure, or platform services at scale
  • Comfort building cloud native infrastructure on GCP, AWS, or Azure
  • 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
  • Interest in problems that don't have existing playbooks
  • Experience building multi-tenant execution platforms or serverless infrastructure
  • Background in security engineering, sandboxing, or isolation technologies
  • Familiarity with workflow orchestration systems (Temporal, Airflow, Step Functions)
  • Experience with state machines, checkpointing, or durable execution patterns
  • 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
