Lead Semantic Layer Engineer

Oracle Health is seeking a Lead Semantic Layer Engineer to build the governed semantic and knowledge foundation that enables AI agents and end users to work from consistent business definitions, trusted metrics, and reusable analytics logic.

This role will own the design and governance of a semantic layer that captures business entities, relationships, metrics, dimensions, hierarchies, glossary terms, lineage, and validation rules across priority analytics domains. This semantic foundation will power AI-driven analytics use cases such as metric design, natural-language search, self-service reporting, dashboard generation, and executive narrative creation.

The ideal candidate combines strong analytics engineering and data modeling experience with a deep understanding of metric governance, business semantics, and how trusted definitions support both human and AI consumers. This role is central to ensuring that AI outputs are accurate, explainable, and aligned with Oracle Health business meaning.
