- Investigate and resolve correctness, performance, and stability issues in the agent integration layer across macOS, Windows, and Linux.
- Drive the reliability and performance of sandbox creation, session management, and teardown for AI agent workloads.
- Collaborate with peers, Product, and adjacent teams to evolve the architecture as requirements grow.

- Familiarity with the agentic software development ecosystem: how coding agents work and how tools like Claude Code, Codex, or similar agents interact with their environment.
