- Build robust backend services and APIs that support the full lifecycle of AI Agent applications, including integration with internal tools, data systems, and business workflows.

- Improve the quality and production readiness of AI applications through systematic work on evaluation, online experimentation, canary release, monitoring, fallback mechanisms, and performance optimization.

- Stay current with frontier AI technologies and apply them pragmatically in high-value security scenarios, working closely with domain experts to turn emerging capabilities into measurable business impact.
