What this posting asks for

Level: Not stated — The posting does not state a level or years of experience.

Main responsibilities

• Design, build, and operate the sandboxing infrastructure that runs untrusted, model-generated code and agent workloads at scale
• Improve sandbox startup time, density, and throughput, including snapshot and restore, checkpointing, and warm pools
• Strengthen isolation across compute, filesystem, and network, including egress controls and per-session credential handling
• Investigate and fix performance, reliability, and security issues at the kernel, hypervisor, and container runtime level
• Build the monitoring, tracing, and debugging tools that show where time and resources go inside a sandbox
• Work with researchers to support reinforcement learning environments and evaluations that need fast, reproducible, isolated execution
• Work with product and platform engineers to expose sandboxes as a dependable, well-designed capability for Claude products and customers
• Partner with security teams to threat-model the platform and to test, harden, and respond to escape and abuse scenarios
• Work with cloud providers on the hardware and platform features that our workloads depend on
• Share knowledge on systems programming and Linux internals, and help set technical standards for the team

Competencies an interviewer will look for

• Technical skill Core
