The opportunity
Claude App Infrastructure owns the reliability, experience, and agentic capabilities of claude. ai.
What you'll do
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
Experience building distributed systems, infrastructure, or platform services at scale
What they're looking for
- 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)
