Develop data strategies for training and evaluating models including human-authored/annotated data and synthetic data.
Own requirements related to ontology tools, metrics, and process improvements.
Create, validate and review requests for ontology changes. Work with cross-functional teams to gather requirements across components and negotiate inter-team constraints.

Minimum 3 years experience of product development working with taxonomies, data classification, or creating ontologies.A curiosity about natural language understanding and its associated complex problems such as the representation of ambiguity.Experience working cross-functionally with machine learning and product engineering teams, data science teams, annotation teams, and designers.Demonstrated experience with systems thinking, particularly gathering requirements, identifying and resolving conflicts.Enjoy working on a diverse set of hard problems in a fast-moving product development environment.Bachelors degree or higher in Computer Science, Linguistics, or science / mathematics degrees.
