Role : AI Context Architect

Experience:
10+ Years Relevant

Experience:
Atleast 3+ Years as AI Architect is mandatory

Location:
Chennai / Bengaluru Role Summary The AI Context Architect designs enterprise knowledge and context architectures that enable AI agents, copilots and applications to access accurate, secure, relevant and trustworthy information. The role focuses on building enterprise semantic layers using ontologies, taxonomies, semantic models and Knowledge Graphs. It architects GraphRAG and hybrid graph-vector retrieval solutions across Neo4j, Amazon Neptune, vector databases, relational databases and NoSQL platforms. The architect establishes governance over metadata, lineage, entity resolution, access control and explainability, while exposing trusted enterprise context through secure APIs and Model Context Protocol (MCP) servers. The ideal candidate is a hands-on AI-native engineer-architect capable of delivering production-grade knowledge and retrieval solutions, defining reusable reference architectures and supporting enterprise AI initiatives.
