How much do ontology jobs pay per hour?
As of Aug 17, 2026, the average hourly pay for ontology in the United States is $19.35, according to ZipRecruiter salary data. Most workers in this role earn between $15.87 and $21.15 per hour, depending on experience, location, and employer.
What is an ontology?
An Ontology job involves designing, developing, and managing structured frameworks that define relationships between concepts in a specific domain. Ontologists work with knowledge representation, semantic data modeling, and taxonomies to improve data interoperability and retrieval. They often collaborate with data scientists, engineers, and domain experts to ensure accurate and meaningful data organization.
What are the typical daily responsibilities of an ontology specialist?
As an Ontology Specialist, your daily tasks often involve designing and maintaining domain ontologies, collaborating with subject matter experts to capture and model knowledge, and working closely with data engineers and software developers to implement semantic solutions. You may also be responsible for updating and optimizing existing ontologies, conducting quality checks to ensure data consistency, and documenting changes for team reference. Additionally, participating in meetings to gather new requirements or resolve data integration challenges is common. This role requires a balanced mix of independent technical work and active communication with various stakeholders to ensure semantic models meet both technical and business objectives.
What are the key skills and qualifications needed to thrive in the ontology position, and why are they important?
To excel as an Ontology Specialist, you need a strong background in information science, semantic modeling, and data analysis, often supported by a degree in computer science or related fields. Familiarity with ontology development tools like Protégé, knowledge of OWL/RDF/SPARQL, and experience with database management systems are highly valuable. Strong analytical thinking, attention to detail, and effective communication skills are crucial for bridging technical concepts with business needs. These skills ensure precise structuring of complex data, effective interdisciplinary collaboration, and the creation of robust, scalable ontology solutions.
How much do ontologists make?
Ontologists typically earn a salary ranging from $60,000 to $120,000 annually, depending on experience, education, and industry. Advanced skills in knowledge modeling, semantic technologies, and relevant certifications can influence earning potential.

Job description
Job Summary:
Veracity Software Pvt. Ltd. is seeking a Microsoft Fabric Ontology Engineer to design and maintain enterprise ontologies and knowledge graphs. The role involves collaboration with data engineers and business stakeholders to map ontological concepts and enable natural language Q&A in Power BI.
Responsibilities:
• Design and maintain enterprise ontologies and knowledge graphs aligned to business domains (finance, HR, supply chain, etc.) within Microsoft Fabric
• Build and manage semantic models in Power BI using ontology-driven design principles, including entity hierarchies, relationships, and synonym mappings
• Define and enforce data definitions, business glossaries, and metadata standards across the Fabric lakehouse and warehouse layers
• Collaborate with data engineers to map ontological concepts to OneLake, Fabric Lakehouses, and Delta Lake tables
• Integrate ontologies with Microsoft Purview for data cataloguing, lineage tracking, and governance
• Develop domain-specific ontologies using standards such as OWL, RDFS, and SKOS, and expose them through Fabric APIs or semantic endpoints
• Enable natural language Q&A and Copilot experiences in Power BI by enriching semantic models with ontological metadata
• Work with AI/ML teams to provide structured ontological features for Azure OpenAI and Fabric's AI workloads
• Establish best practices and documentation for ontology lifecycle management — versioning, deprecation, and change governance
• Collaborate with business stakeholders to capture and formalise domain knowledge into machine-readable models
Qualifications:
Required:
• 13+ years of experience
• Hands-on experience with Microsoft Fabric (Lakehouse, Warehouse, Data Factory, Notebooks, Semantic Models)
• Strong proficiency in Power BI semantic modelling — DAX, relationships, hierarchies, calculation groups
• Experience with OneLake and Delta Lake table formats
• Familiarity with Microsoft Purview for data cataloguing and lineage
• Proficiency in ontology languages: OWL (Web Ontology Language), RDFS, SKOS
• Experience with ontology development tools such as Protégé, TopBraid Composer, or similar
• Understanding of RDF (Resource Description Framework) and SPARQL for querying knowledge graphs
• Ability to design taxonomies, thesauri, and controlled vocabularies
• Knowledge of linked data principles and URI-based entity identification
• Strong SQL skills across T-SQL and Spark SQL
• Experience with Python or PySpark for data transformation and ontology integration pipelines
• Familiarity with REST APIs and JSON-LD for publishing and consuming semantic data
• Understanding of medallion architecture (Bronze / Silver / Gold) within a lakehouse context
• Awareness of how ontologies enhance LLM-based applications (RAG pipelines, grounding, entity disambiguation)
• Experience or interest in integrating ontologies with Azure OpenAI Service or Microsoft Copilot Studio
• Familiarity with knowledge graph platforms (e.g. Azure Cosmos DB, Neo4j, or AWS Neptune)
Preferred:
• Experience with industry-standard ontologies such as FIBO (finance), HL7 FHIR (healthcare), GS1 (retail), or PROV-O (provenance)
• Background in enterprise data governance or MDM (Master Data Management)
• Microsoft certifications: DP-600 (Fabric Analytics Engineer), PL-300 (Power BI), or SC-400 (Information Protection)
• Degree in Computer Science, Information Science, Knowledge Engineering, or a related field
Company:
At Veracity, if you have an idea you want to validate, a product you need to build, or an existing product that needs optimization, our teams are trained to jump in wherever needed. Founded in 2010, the company is headquartered in Iselin, USA, with a team of 51-200 employees. The company is currently Growth Stage.
