Salary
$128,000 - $170,000
What they actually want (must-haves)
  • Greater than 4 years of experience in knowledge engineering, ontology development, or a closely related formal methods discipline.
  • Demonstrated experience building and maintaining domain ontologies in Protege or equivalent, with reasoner-validated consistency; not solely taxonomy or metadata management work.
  • Experience with ROBOT or ODK for ontology lifecycle management (or similar): automated quality checks, versioning, release pipelines.
  • Expertise in SPARQL and/or Cypher for querying ontology-aligned data stores; ability to write and evaluate queries that correctly reflect ontological intent.
  • Demonstrated ability to interpret data profiling output and translate it into formal ontological claims; experience with empirical ontology discovery from data as well as top-down ontology design.
  • Experience directing or evaluating LLM-assisted knowledge extraction pipelines with formal validation requirements.
Nice to have
  • Bachelor's or advanced degree in Computer Science, Mathematics, Philosophy (logic/formal methods), Information Science, or a related hard science discipline.
  • Familiarity with category theory as applied to data integration -- functors, natural transformations, limits and colimits as schema merge operations -- at literacy level or above; knowledge of CQL/AQL or categorical database theory is a plus.
  • Experience with LinkML.
  • Healthcare supply chain domain knowledge and ontological structures.
  • Experience with BFO 2.0 and the OBO Foundry principles and standards.
What the job really is

The Senior Data Scientist - Ontology will focus on designing and maintaining the formal ontological architecture for cross-organizational data alignment within the AI, ML, and Data Science team. This role involves establishing rules for data alignment, authoring OWL 2 axioms, and collaborating with various stakeholders to ensure the ontological architecture supports clinical and analytical requirements. The engineer will also direct LLM-assisted ontology extraction pipelines and monitor developments in knowledge representation.

Benefits
  • Estimated Salary: $128,000 - $170,000
Things to weigh
  • Role requires a deep understanding of formal ontology and knowledge representation, which may not be suitable for those without a strong background in these areas.
  • No specific mention of remote work flexibility beyond the location being 'Office Location or Remote - USA'.
  • The role involves high-level decision-making and formal correctness, which may lead to pressure in design evaluations and stakeholder communications.
