We are looking for a Senior/Lead Automation Tester in Python to own functional and regression test suites for agentic memory behavior within an Enterprise Agent Development Platform - a production-grade, cloud-native ecosystem that enables engineering teams to define, orchestrate, deploy, and observe AI agents at scale. The platform standardizes agent development across the organization using LangGraph and Strands Agents on AWS AgentCore Runtime, spanning 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.

• Conduct memory retrieval testing to validate agents retrieve relevant context and filter irrelevant memories
• Perform memory lifecycle testing, including TTL expiration, user deletion, and namespace isolation
• Run agent regression testing to verify memory does not degrade agent response quality
• Build Python test automation for memory workflows

Requirements

• 3+ years of experience in QA engineering for AI/ML or conversational AI systems
