The Senior Ontology Engineer role at the Systems Engineering & Analysis Division in King George/Dahlgren, Virginia involves designing and maintaining ontological frameworks and knowledge graph solutions for defense mission engineering programs. This individual will work closely with software engineers, systems architects, and domain experts to develop scalable knowledge representations that integrate structured and unstructured data across multi-domain systems. Key responsibilities include building formal ontologies using OWL, RDF/RDFS, and SPARQL, deploying knowledge graphs on platforms like Stardog or Neo4j, and integrating large language models into AI pipelines. The ideal candidate has extensive experience with semantic web technologies, graph databases, and Python frameworks such as TensorFlow and rdflib, along with a background in technical writing for proposals related to AI adoption in the Navy.
