## About the role

Make agents legible, first-class users of our infrastructure. Each one gets an identity of its own, reaches exactly what its task needs and nothing else, and leaves a trail a person can later audit. Build environments for our agents to run in, e.g. short-lived VMs that exist for one task and no-egress sandboxes for long runs.

## What they're looking for

- Have run production infrastructure somewhere dynamic and know which shortcuts you’ll regret
- Use coding agents heavily and have strong opinions on what you let them do, what you don't, and how you verify their work
- Built engineering workflows (methodology, flow automation, review tooling, agent harnesses) that other engineers adopted and kept
- Notice LLM agents asserting something confidently wrong and modify their harness in response
- Have operated Bazel remote execution or a remote cache
- Are familiar with sandboxing and ephemeral compute for untrusted workloads
