The R&D Data Science organization is recruiting for a Principal Data Scientist Ontology Developer TDS to design build and govern the semantic frameworks that unify data across the developmenttodelivery lifecycle for Therapeutics Development & Supply (TDS). You will translate scientific technical and operational concepts into wellstructured ontologies controlled vocabularies and semantic models that enable interoperability analytics automation and AI/ML applications across TDS.

This role combines handson ontology engineering with product-oriented thinking partnering closely with domain experts in Process Development Manufacturing Quality Supply Chain and Data Science teams. You will serve as a key technical contributor and creative problem solver with a strong understanding of semantic technologies and data modeling in life sciences or manufacturing domains.

Key Responsibilities

Ontology Design Development & Release

• Model code test and publish ontology modules and controlled vocabularies supporting our TDS data ecosystems (e.g. process development material attributes equipment hierarchies batch and product genealogy quality signals supply chain flows).

• Translate domain knowledge from SMEs into OWL/RDF classes and properties SKOS vocabularies and SHACL constraints following patterns from established ontology engineering practices.

• Produce validated versioned semantic models and APIready outputs for integration into enterprise platforms.

• Build mappings to enterprise canonical models regulatory standards and crossfunctional ontologies.

Governance Standards & Quality

• Maintain accountability for components of the TDS ontology roadmapsetting scope priority use cases and success metrics.

• Define and enforce modeling guidelines naming and versioning conventions change control processes and release/deprecation rules similar to R&D ontology governance frameworks.
