Principal Scientist, Data Science (Translational Knowledge Engineering)

Position Summary The Principal Translational Knowledge Architect & Graph Lead designs and implements semantic and knowledge architecture enabling AI-driven reasoning across the drug discovery and development lifecycle. Leads ontology development, knowledge graph design, semantic interoperability, and AI-ready knowledge representation. Mission Build the semantic foundation for AI reasoning across discovery, preclinical, clinical, and post-marketing domains while preserving scientific meaning, provenance, and translational fidelity. Key Responsibilities Design/maintain enterprise knowledge models (discovery biology, toxicology, safety pharmacology, pathology, clinical development, pharmacovigilance, real-world evidence). Lead ontology strategy, development, governance, lifecycle management; ensure semantic consistency, provenance/traceability, and FAIR. Design RDF-based knowledge graph architectures; develop mappings/inference rules/reasoning frameworks. Enable GraphRAG/semantic retrieval/AI agents/next-gen translational intelligence via suitable knowledge representations. Develop semantic bridges across SEND, SDTM, ADaM, MedDRA, HPO, MONDO, SNOMED CT, FHIR, OMOP, Cell Ontology, Protein Ontology. Partner cross-functionally with Discovery, Preclinical Safety, Clinical Development, Pharmacovigilance, Data Science/Digital Health; collaborate with engineering/platform teams. Required Qualifications PhD or Master’s in Biomedical Informatics, Bioinformatics, Computational Biology, Computer Science, Information Science, Knowledge Engineering, or related field. 5+ years in biomedical informatics/semantic technologies/knowledge engineering/scientific data architecture. Demonstrated ontology-driven knowledge system design; experience across multiple drug discovery/development phases. Technical Expertise Ontology development/governance; knowledge representation; RDF/OWL/SHACL/SPARQL; Semantic Web technologies. Preferred Qualifications Experience building semantic foundations for AI/GraphRAG/agentic AI/scientific reasoning; familiarity with LLM retrieval/reasoning. Support translational safety/efficacy/biomarker/mechanistic reasoning; contributions to ontology standards/open-source biomedical ontologies/knowledge graphs.
