Job description

Responsibilities We are seeking an Ontologically Aware Data Scientist to design, build, and operationalize knowledge‑centric AI/ML systems that integrate ontology engineering, semantic data modeling, and advanced analytics. This role blends deep experience with RDF/OWL/SHACL and graph data models with practical machine learning, natural‑language processing, and context engineering. You will develop semantic foundations and AI-driven tooling that enable multiple organizations to communicate using shared ontologies and that support natural‑language‑to‑SPARQL interfaces with reduced hallucination. Responsibilities: - Develop and maintain logical, semantically rich, extensible ontologies (RDF/OWL/SKOS) aligned to foundational/top‑level ontologies (BFO, DOLCE, CCO, OBO Foundry). - Build and evolve canonical vocabularies that unify heterogeneous datasets across organizational boundaries. - Design, implement, and maintain knowledge graphs and semantic data models using AnzoGraph including modeling tradeoffs, query optimization, and production operations. - Create SHACL validation layers; run regular quality checks to ensure consistency, backward compatibility, and schema integrity. - Writ...
