Python engineer for agent integration

We are looking for a Senior Python Backend Engineer to build and integrate agent-to-agent communication capabilities on AWS AgentCore platforms. The role focuses on Python backend development, A2A protocol implementation, agent discovery and registration, event-driven communication, and scalable multi-agent interactions. The ideal candidate has strong backend engineering experience, expertise in asynchronous systems, and hands-on knowledge of modern API and agent integration patterns.

• Design and implement backend services using Python and AWS AgentCore SDK.
• Build and maintain A2A integrations using AWS AgentCore Runtime and Gateway.
• Implement agent registration, target configuration, and agent discovery workflows.
• Develop and maintain Agent Card definitions and .well-known/agent.json endpoints.
• Implement A2A communication patterns using JSON-RPC 2.0 and event-driven architectures.
• Design and support agent invocation workflows between caller and target agents.
• Build asynchronous communication flows using SSE, webhooks, and push notifications.
• Develop REST APIs and backend services that enable reliable agent interaction and routing.
• Implement event lifecycle handling, task status tracking, and agent execution monitoring.
• Ensure secure and scalable communication between distributed agents and services.
• Collaborate with AI, platform, and security teams to support multi-agent ecosystem integration.
• Troubleshoot, test, and optimize backend services for performance, reliability, and scalability.
• Produce technical documentation for integration standards, APIs, and agent connectivity patterns.

• Python (async, AgentCore SDK, REST)
• AWS AgentCore Runtime and Gateway (agent card registration, target configuration)
• A2A agent invocation patterns (caller and target template integration)
• A2A protocol wire format (JSON-RPC 2.0, SSE task lifecycle events, push notifications)
• Agent Card JSON schema authoring and /.well-known/agent.json endpoint implementation
• 5+ years Python or Go backend engineering
• API integration and routing
• Agent or microservice communication patterns
• REST API implementation (building endpoints, not just consuming them)
• Understanding of async/event-driven patterns (SSE, webhooks)
• Будет плюсом: AWS AgentCore Gateway template integration validation; AWS Bedrock multi-agent invocation patterns; SSE event streaming (task lifecycle events, push notifications); OpenTelemetry trace propagation across A2A agent hops (ADOT)
