Own the end-to-end architecture for the AI Native Intelligence platform on AWS - ingestion, enrichment, the semantic/business ontology layer, retrieval-augmented generation (RAG), knowledge graphs, and agentic orchestration (Amazon Bedrock, Bedrock AgentCore, Amazon Neptune, OpenSearch Serverless, AWS Glue, Amazon Transcribe/Comprehend, and related services). This is a hands-on, builder-leader role: someone who sets the technical vision and roadmap, but who is equally comfortable reviewing a Bedrock agents tool-calling logic, debugging a Step Functions pipeline, or sketching a knowledge graph schema on a whiteboard.
