Ontology & Semantic Architect

The Ontology & Semantic Architect is a strategic and technically strong leader responsible for building and guiding our Ontology strategy. This person is responsible for designing governing and scaling the semantic blueprints that give meaning and structure to our enterprise data. Ontology in our organization defines the concepts relationships and rules that shape how systems understand and interact with dataenabling consistency interoperability advanced analytics and AI-driven capabilities.

The role will oversee the development and stewardship of our enterprise ontology across Microsoft Fabric (including Fabric IQ) and Palantir platforms. This leader will collaborate across business and technical teams to ensure that our semantic models accurately reflect business definitions enable high-confidence data usage support cross-system integration and power next-generation analytics and AI.
