The Ontologist (Knowledge Graph Engineer) at the Customer Data Ecosystem (CDE) is a senior-level role responsible for designing and operationalizing enterprise semantic models to enable trusted analytics, AI, and agentic systems. This involves creating ontologies and knowledge graphs that standardize business meaning across domains, ensuring LLMs and agents can consume governed context and rules. The engineer will work with architects and engineers to embed semantic models into data products and pipelines, aligning them with enterprise governance standards while promoting best practices for ontology reuse. Key technologies include RDF, OWL, SPARQL, and graph databases like Neo4j or Neptune, alongside experience in AI consumption patterns and integrating semantic layers with cloud platforms such as AWS, GCP, and Snowflake.
