- Review and verify AI-generated code before it reaches production, including testing edge cases, security implications, and overall quality.
- Maintain strong engineering and architectural standards in an AI-assisted codebase.
- Debug production issues across services using telemetry and observability tools.
- Collaborate with Product Managers, Designers, DevOps, and QA.
- Quickly adapt to unfamiliar technologies and ecosystems when required.
