Job Description
About the Role
We are looking for a hands-on Ontology / Knowledge Graph Engineer who understands not just graph databases, but the true semantic foundations behind enterprise knowledge graphs. This role requires experience in building domain ontologies, modeling conceptual semantics, and connecting those models to enterprise data sources.
This is not a Cypher-only graph querying role.
This is a role for someone who has worked with OWL/RDF, domain modeling, and semantic standards—and can translate complex insurance concepts into a formal ontology that powers AI, LLMs, data governance, and enterprise knowledge systems.
Key Responsibilities
1. Ontology Design & Semantic Modeling
Design, model, and maintain insurance domain ontologies using OWL/RDF.
Build conceptual and logical semantic models for entities such as:
Policies, Coverages, Perils, Claims, Loss Events, Parties, Risk Objects, Brokers/Agents.
Define canonical data definitions, taxonomies, hierarchical relationships, and semantic constraints.
Translate business domain models and regulatory structures into formal semantic structures.
2. Knowledge Graph Architecture
Design and extend production-grade knowledge graphs derived from ontologies.
Make design decisions on:
How the ontology becomes the semantic index for enterprise data.
How graph nodes point back to source systems through schema mapping.
How the KG will be used in RAG, LLM context grounding, or reasoning pipelines.
Implement ontology-driven schemas using RDF stores or labeled-property graph stores.
3. Source System Mapping
Parse schemas from policy admin, claims, CRM, billing, and underwriting systems.
Map source fields to ontology entities using:
Schema parsing
Semantic mapping
Transformation rules
Ensure semantic alignment and consistency across diverse insurance systems.
4. Azure Cloud Integration
Deploy and operationalize ontology and KG components using:
Azure Data Lake / Storage
Azure Purview / Microsoft Fabric Catalog
Azure Cognitive Search (for semantic indexing)
Azure Kubernetes Services / Azure Functions (for KG pipelines)
Azure OpenAI (for semantic enrichment, RAG, and reasoning)
Integrate KG metadata into Azure metadata and lineage systems.
5. Collaboration & Governance
Work closely with:
Underwriting SMEs
Claims SMEs
Data governance teams
Data engineering teams
AI/ML product teams
Document semantic models, maintain change logs, and drive ontology versioning.
Required Skills (Non-Negotiable)
Hands-on experience in ontology development, not just graph querying.
Strong knowledge of:
OWL, RDF, RDFS, SKOS
SPARQL, SHACL (preferred)
Experience designing conceptual and logical domain models.
Demonstrated ability to build a knowledge graph from scratch, not just use one.
Strong insurance domain understanding:
Policy structures
Exposure / risk modeling fundamentals
Claims life cycle
Product hierarchies
Regulatory constraints
Ability to map enterprise source schemas to semantic models.
Experience with at least one semantic technology stack:
Stardog, GraphDB, Neo4j (with RDF frameworks), TopQuadrant, AllegroGraph, etc.
Nice-to-Have Skills
Experience building LLM-integrated semantic pipelines:
Context engineering
RAG indexing
Metadata grounding
Familiarity with Azure OpenAI or similar LLM orchestration frameworks.
Understanding of industry data standards such as ACORD.
Soft Skills
Strong analytical and conceptual modeling skills.
Ability to challenge assumptions and define canonical definitions.
Ability to communicate with business SMEs and translate domain knowledge into ontology structures.
Structured documentation and versioning discipline.
Why This Role Matters
This role is foundational to:
Enterprise LLM adoption
Semantic search
Knowledge-driven underwriting & claims workflows
Data governance
AI safety & consistency
Eliminating redundant and fragmented data definitions across systems
