This role defines and enforces standards for data modeling, taxonomy, semantic structures, and knowledge representation to ensure consistency, interoperability, and clarity across the organization.\nThe Semantics Engineer (Ontologist) partners closely with business and technology teams to develop and maintain the enterprise data domain model and ontologies that support governance frameworks, trusted analytics, and downstream consumption across business intelligence (BI), applied AI/ML, and Large Language Model (LLM) use cases. Success in this role requires the ability to translate complex theoretical concepts into scalable, governed information structures that drive adoption of the data catalog, support emerging AI capabilities, and deliver measurable value to colleagues.\nESSENTIAL JOB FUNCTIONS:\nLead the development and maintenance of the enterprise data domain model, taxonomy, and ontologies to ensure shared understanding, semantic consistency, and discoverability of data and knowledge assets.\nDesign and evolve information and semantic models that make enterprise data AI-ready, supporting use cases ranging from traditional analytics and BI to applied machine learning and LLM-based experiences (e.g., search, retrieval-augmented generation, and copilots).\nOperationalize data models, taxonomies, and semantic structures through the Enterprise Data Catalog (Alation).\nDefine and enforce standards for data modeling, taxonomy, nomenclature, and semantic structures to ensure consistency and interoperability across business domains and downstream consumption patterns.\nProvide authoritative guidance on semantic conflicts-resolve definition discrepancies, harmonize terms, and mediate cross-domain dependencies to establish trusted, reusable business meaning.\nContribute to the enterprise data product framework by defining domain boundaries, shared dimensions, and semantic contracts that enable cross-domain interoperability and AI consumption.\nConfirm and document prioritized metadata elements for key business processes, analytical use cases, and AI-enabled workflows, ensuring alignment with governance standards and risk expectations.\nIdentify simplification opportunities-reduce redundancy, converge overlapping datasets, and promote canonical sources to improve trust, efficiency, and reusability across analytics and AI platforms.\nPartner with analytics, data science, and AI engineering teams to ensure information architecture, metadata, and semantic context are sufficient to support explainable, governed, and trustworthy AI outcomes.\nServe as a thought partner, provide insights from modeling, catalog adoption, and AI enablement to shape governance strategy and roadmaps.\nREQUIRED EXPERIENCE:\n10+ years of experience working with data, metadata, and reference data frameworks, including experience in metadata management and/or data quality monitoring\nExperience leading the development of enterprise business glossaries, domain models, and ontologies to enable semantic consistency, shared understanding, and AI ready data usage.\nDemonstrated experience with data management concepts including data governance, data quality, master data management, data lineage, and metadata management.\nProven ability to establish and operationalize metadata governance functions, including policies, standards, roles, and controls.\nDemonstrated verbal and written communication skills, with strong data, metadata, and governance storytelling that drives adoption and influences stakeholders.\nHands on experience implementing and scaling an Enterprise Data Catalog or metadata repository (Alation or equivalent), including curation workflows and adoption strategies.\nUnderstanding of how semantic models, metadata, and knowledge representation enable applied AI and LLM use cases, such as search, question answering, and decision support.\nStrong business acumen in relating data to business process drivers and performance management, with a value delivery mindset.\nCollaborative, team focused delivery experience that drives outcomes across enterprise data, analytics, and technology organizations.\nStrategic thinker with the ability to translate enterprise objectives into actionable plans and measurable outcomes.\nExcellent knowledge of data and metadata management principles, business analysis, and process engineering.\nTECHNOLOGIES:\nKnowledge Graphs\nNeo4j\nStardog\nAmazon Neptune / Azure Cosmos DB (Graph)\nOntology & Semantic Modeling\nOWL / RDF / SKOS\nProtégé\nTopBraid\nStardog Studio\nEnterprise Data & Knowledge Catalogs\nAlation\nCollibra\nMicrosoft Purview\nDataHub\nKnowledge Modeling Techniques\nOntologies & domain models\nBusiness vocabularies & taxonomies\nSemantic normalization\nEntity & relationship modeling\nAI Context Delivery (Grounding Layer)\nVector databases (Pinecone, Weaviate, Azure AI Search)\nGraph + vector retrieval (hybrid RAG)\nMetadata-driven prompt context\nCOMPENSATION AND BENEFITS\nThis position is eligible to earn a base salary in the range of $96,000.00 - $181,000.00 annually.
