Description

• Design, build, deploy, secure, and operate production-ready AI agents using the AWS Strands Agents SDK and Amazon Bedrock AgentCore.

• Architect reusable agent platform components, APIs, deployment patterns, and controls for scalability, availability, observability, governance, and cost efficiency.

• Build AWS Lambda and Glue-based ingestion pipelines for parsing, metadata enrichment, chunking, embeddings, vector indexing, synchronization, and data-quality validation.

• Design Bedrock Knowledge Base and custom RAG solutions, selecting and tuning chunking, embedding, vector store, metadata, retrieval, reranking, and HNSW/IVF index strategies.

• Integrate automated retrieval, response-quality, regression, and safety evaluation into CI/CD release gates.

• Maintain a governed, versioned prompt library and develop platform services, automation, and integrations in Python and JavaScript.

• Implement monitoring, tracing, logging, alerting, security, and troubleshooting across agents and data pipelines.

• Collaborate with product, data, security, DevOps, and application teams to deliver reliable, maintainable AI solutions."
