Ontology Engineer

Visilayer is the AI Recommendation Layer company. AI systems now decide which businesses get discovered, compared, and recommended, and most businesses are invisible or described incorrectly in those answers. We build the structured knowledge infrastructure that lets AI understand, compare, and accurately represent a business, so our clients are read correctly, completely, and confidently. The category is only just forming, and the people who join now will help define it.

Design the structured knowledge that makes Visilayer work, the taxonomies, ontologies, and fact models, and tag client content against them so AI systems can read, compare, and cite it. This is Visilayer's differentiator.

• Design and maintain the taxonomies and ontologies across client industries.
• Model messy real world client facts into clean, machine readable knowledge.
• Define how facts map to schema.org and to the formats AI systems consume.
• Tag and quality check client content against the taxonomy.
• Build and refine the predicate and relationship library.
• Partner with engineering to turn the models into product, and with strategy to keep them grounded in client need.

• Background in knowledge representation, ontologies, taxonomies, library and information science, linguistics, or data modeling.
• A rigorous, structured thinker who is comfortable with both ambiguity and detail.
• Able to translate messy real world information into clean, consistent models.
• Comfortable with structured data formats such as JSON, JSON-LD, and RDF concepts.
• Experience with knowledge graphs, Neo4j, or semantic web tools.
• Familiarity with schema.org and with search or AI visibility.
• Domain knowledge in hospitality or multi location business.

Visilayer is early and small, which means real ownership, a short line from your work to the result, and the chance to help shape a brand new category rather than maintain an old one. We work remotely across the United States.
