Biomedical Ontologist

Career Guide
A Biomedical Ontologist designs and maintains structured vocabularies that help biomedical data use the same meanings across research, clinical, and product systems. This work improves data consistency, search, analytics, and the ability to link information across studies, databases, and applications.

Key Responsibilities

  • Create and maintain ontology terms, definitions, and relationships for biomedical concepts
  • Work with scientists, clinicians, and data teams to capture domain knowledge accurately
  • Map between existing standards and local vocabularies to support data integration
  • Review incoming term requests and manage change over time
  • Validate ontology quality using consistency checks and expert review
  • Document ontology decisions and publish updates for stakeholders
  • Support search, annotation, and data labeling workflows using controlled terms
  • Collaborate with engineering teams to implement ontology use in data pipelines and tools
  • Contribute to governance processes for terminology and standards adoption
