The platform standardizes agent development across the organization using LangGraph and Strands Agents on AWS AgentCore Runtime, providing a single-file developer experience where the platform handles runtime, tooling, observability and deployment automatically. The initiative spans agent framework design, runtime architecture, marketplace integration, CI/CD automation and enterprise-grade observability — reducing agent development from months to days while enforcing consistent security, quality and governance standards.

- Own the functional policy test suite covering permit/deny correctness, forbid-overrides-permit and parameter-level conditions
- Manage LOG_ONLY to ENFORCE mode switching validation
- Develop functional and security test design strategies
- 3+ years of experience in quality assurance or security testing
- Background in automated security test suite implementation
- Expertise in API security testing (OWASP API Top 10)
