Senior Python Engineer (A2A Integration)

Sobre a vaga

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.

O que vais fazer

• 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

O que é pedido

• 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)

Valorizado

• 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)
