[Job - 32565] AI Engineer Senior, Brazil
CI&T, Brazil
The role
You will build and maintain the core components teams use to ship agents: the Python SDK, agent and MCP templates, memory and context services, the agent registry integration and the FastAPI entry layer. You will often own one component end to end, as primary support.
What you will do
- Build SDK features and framework adapters (Strands, Claude Agent SDK, LangGraph), including memory (AgentCore Memory short- and long-term, Redis), skills, prompt management integration, and evaluation hooks.
- Build and maintain agent and MCP server templates for AgentCore Runtime and ECS Fargate, over HTTP and A2A.
- Integrate with the AWS Agent Registry: registration, approval flow, identity-scoped discovery. Build and support RAG and knowledge services (Bedrock Knowledge Bases, OpenSearch vector, ingestion pipelines).
- Write contract and integration tests.
- Keep the release parity gate green.
- Help use-case teams onboard, debug their agents, and feed what you learn back into the platform.
