Job description

You'll design and maintain formal ontologies grounded in Basic Formal Ontology (BFO 2020) and the Common Core Ontologies (CCO), extending them to model the domain-specific realities of global corporate taxation.

What you'll do:

  • Design BFO-compliant ontological structures that capture tax concepts, relationships, and reasoning patterns
  • Extend CCO frameworks to model jurisdiction-specific tax requirements (US, UK, EU, APAC)
  • Align external schemas—accounting standards, regulatory taxonomies, ERP data models—to our semantic architecture
  • Develop OWL ontologies and SHACL constraints for data validation and automated reasoning
  • Collaborate with data engineers, knowledge graph architects, and tax domain experts to translate professional judgment into formal models
  • Contribute to governance artifacts: naming conventions, documentation standards, version control
  • Support AI/ML explainability by ensuring our semantic foundation makes machine decisions interpretable
You Bring

Required:

  • Master's or PhD in Philosophy, Computer Science, Information Science, Cognitive Science, or related field
  • 3+ years in applied ontology development
  • Deep knowledge of BFO 2020 and familiarity with the CCO suite
  • Proficiency in OWL, RDF, SPARQL, Protégé, and related tools
  • Demonstrated ability to design ontologies for mission-critical use cases
  • Exceptional communication skills—you can explain why modal logic matters to someone who's never heard of Kripke

Preferred:

  • Experience integrating ontologies into production knowledge graphs
  • Background in regulatory, financial, or compliance domains
  • Exposure to semantic reasoning engines or AI systems
  • Participation in standards bodies or ontology governance working groups
  • Familiarity with tax concepts or financial reporting (we'll teach you what you don't know)
