📋 Description

• Design, build, and maintain the enterprise ontology (BFO/CCO-aligned) and controlled vocabularies, and map source-system data into them • Build and manage the knowledge graph using an RDF triple store, SHACL validation, and SPARQL queries • Build the governed ingestion path so extracted content lands in the graph with provenance and confidence, and connect the graph to retrieval and GenAI applications • Perform full-stack development alongside ontology work, including Python services, web UI, and AWS • Work in a small Scrum team and demo working software every sprint

🎯 Requirements

• Active Secret OR Top Secret Clearance Required • 5+ years of hands-on semantic-technology work: OWL, RDF/Turtle, SHACL, and SPARQL • Experience building ontologies aligned to an upper ontology — BFO and CCO strongly preferred • Production experience with a triple store (Apache Jena/Fuseki, RDF4J, or similar) • Solid general software engineering: Python, APIs, Git — able to handle full-stack tasks (web + AWS), not ontology-only • Working familiarity with LLMs and RAG — you’ve connected structured knowledge to generative applications
