Requirements
- 5+ years building and operating production infrastructure, with meaningful exposure to security.
- Deep knowledge of Google Cloud Platform and/or AWS, including compute, networking, IAM, and security services.

- Strong coding ability in at least one systems language (e.g., Python, Go, TypeScript).
- Experience applying AI-assisted tooling (Cursor, Claude Code, etc.) to enhance engineer effectiveness.
- Experience with secure container deployment, service mesh, and Kubernetes security best practices.
