Position Summary
The Principal Translational Knowledge Architect & Graph Lead will be responsible for designing and implementing the semantic and knowledge architecture that enables AI-driven reasoning across the drug discovery and development lifecycle.
This role will serve as the scientific and technical lead for ontology development, knowledge graph design, semantic interoperability, and AI-ready knowledge representation. Working at the intersection of translational science, patient safety, biomedical informatics, and artificial intelligence, this individual will help establish the semantic foundation required to connect discovery biology, preclinical safety, clinical development, real-world evidence, and post-marketing safety into a unified reasoning framework.
The successful candidate will partner closely with scientists, safety experts, data scientists, AI engineers, and platform teams to create knowledge assets that support GraphRAG, agentic AI, scientific reasoning, and next-generation translational intelligence capabilities.
Mission
Build the semantic foundation that enables AI systems to reason across discovery, preclinical, clinical, and post-marketing domains while preserving scientific meaning, provenance, and translational fidelity.
Key Responsibilities
Semantic Architecture & Knowledge Modeling
Design and maintain enterprise knowledge models spanning:
Discovery biology
Toxicology
Safety pharmacology
Pathology
Clinical development
Pharmacovigilance
Real-world evidence
Develop semantic frameworks that support translational reasoning across the R&D lifecycle.
Create conceptual, logical, and physical knowledge models supporting AI-enabled scientific discovery.
Ontology Engineering & Governance
Lead ontology strategy, development, governance, and lifecycle management.
Curate and extend biomedical ontologies supporting translational safety and efficacy use cases.
Establish ontology governance processes, quality standards, and semantic review procedures.
Ensure semantic consistency, provenance, traceability, and FAIR data principles.
Knowledge Graph & Reasoning Infrastructure
Design RDF-based knowledge graph architectures and related semantic technologies.
Develop semantic mappings, inference rules, and reasoning frameworks supporting scientific decision-making.
Define knowledge representations enabling GraphRAG, semantic retrieval, AI agents, and reasoning systems.
Establish semantic interoperability across heterogeneous data sources and standards.
Translational Data Harmonization
Develop semantic bridges across major industry standards and ontologies, including:
SEND
SDTM
ADaM
MedDRA
HPO
MONDO
SNOMED CT
FHIR
OMOP
Cell Ontology
Protein Ontology
Enable AI systems to traverse translational boundaries while preserving biological and clinical context.
Scientific & Cross-Functional Leadership
Partner with stakeholders across Discovery, Preclinical Safety, Clinical Development, Pharmacovigilance, Data Science, and Digital Health.
Collaborate with engineering teams responsible for data products, pipelines, and AI platforms.
Influence enterprise semantic strategy and represent the organization in external standards and ontology communities when appropriate.
Required Qualifications

Related scientific discipline
Experience
5+ years of experience in biomedical informatics, semantic technologies, knowledge engineering, or scientific data architecture.
Demonstrated experience designing ontology-driven knowledge systems in life sciences, healthcare, or pharmaceutical R&D environments.
Experience working across multiple phases of drug discovery and development.
Technical Expertise
Deep expertise in:
Ontology development and governance
Knowledge representation
RDF
OWL
SHACL
SPARQL
Semantic Web technologies
Strong experience with:
Enterprise ontology management platforms
RDF graph architectures
Semantic APIs
FAIR data principles
