Senior Security & Test Engineer, A2A

We are looking for a Senior Security & Test Engineer to take ownership of the security, functional, and performance test suites for our A2A gateway within an enterprise-grade Agent Development Platform. This production-ready, cloud-native ecosystem empowers engineering teams to define, orchestrate, deploy, and monitor AI agents at scale, standardizing agent development through LangGraph and Strands Agents on AWS AgentCore Runtime.

This position centers on verifying Cedar policy enforcement accuracy and performing trust model gap analysis for non-AgentCore A2A agents, ensuring uniform security, quality, and governance standards throughout the platform.

Experience the freedom of remote work from anywhere in Georgia, whether from the comfort of your home, our modern offices in Tbilisi and Batumi or a coworking space in Kutaisi.

• Validate Cedar policy enforcement correctness across LOG_ONLY and ENFORCE modes
• Conduct trust model gap analysis for non-AgentCore A2A agents
• Design and execute functional and security test strategies for agentic AI systems
• Build and maintain Python-based security test automation frameworks
• Perform performance testing and benchmarking for cloud APIs using k6 and Locust
• Test permit/deny correctness and forbid-overrides-permit logic within Cedar policies
• Apply agentic AI and LLM threat modeling practices to identify risks such as excessive agency and tool parameter exfiltration
• Evaluate A2A trust model components, including OAuth 2.0, signed Agent Cards, JWT validation, and token scope enforcement for agent channels

Requirements

• 3+ years of experience in security engineering or QA
• Expertise in API security testing and performance benchmarking for cloud APIs
• Skills in security test design for AI/agent systems beyond traditional REST APIs
• Background in enforcement mechanism design or implementation
• Knowledge of A2A trust model concepts, including OAuth 2.0, signed Agent Cards, JWT validation, and token scope enforcement
