In this role, you will lead the design and implementation of the AWS AgentCore Gateway for an enterprise AI agent development platform. You will architect and enforce the A2A protocol for secure and efficient agent-to-agent interactions, drive authentication and routing models, and ensure the gateway is resilient and production-ready. This position offers an opportunity to work on cutting-edge multi-agent systems, enabling global-scale AI orchestration within highly secure environments.

- Develop backend features in Python leveraging the AgentCore SDK for gateway interaction
- Perform performance benchmarking and security hardening for critical gateway workloads
- Collaborate with platform, security, and orchestration teams on governance models for multi-agent environments
- Support enterprise-scale deployment, monitoring, and resilience of A2A traffic flows
Requirements
- 5+ years of experience in platform or backend engineering roles
- Hands-on production experience with agent-to-agent (A2A) or agent-to-tool gateway platforms
- Strong knowledge of OAuth 2.0 authentication and identity-driven routing models
- Proven experience implementing machine-to-machine trust models in production systems
- Practical understanding of multi-agent system architectures and invocation lifecycle
- Proficiency in Python backend development for platform-level services
- Familiarity with AWS-native architectures and deployment strategies for cloud-native systems
