Ontology & Semantic Architect

Overview

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 data—enabling 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.

• Lead the creation and management of semantic models within Microsoft Fabric IQ, including domain modeling, semantic enrichment, and unified business definitions.
• Oversee the design and governance of Palantir Ontology artifacts, including object types, relationships, functions, schema transformations, and operational pipelines.
• Ensure consistency and alignment between semantic models implemented in Palantir and those implemented in Fabric.
• Drive best practices for building scalable data models, ontology-driven access patterns, and knowledge graph structures across platforms.

• Define the enterprise semantic architecture, including how ontologies integrate with data products, data pipelines, APIs, and AI/ML solutions.
• Establish and maintain a semantic layer strategy to ensure business-aligned meaning across systems.
• Partner with integration and API teams to ensure semantic alignment in data contracts and experience APIs.
• Promote an ontology-driven approach to data interoperability, lineage, data quality, and governance.
