The vision of Amazon Business Catalog Taxonomy Team (ABCT) is to empower large enterprise customers to manage, audit and plan their spend by providing them tools based on a collection of standardized, semantically rich, extensible and universally applicable product taxonomies. In the B2B e-commerce space, customers are particularly interested in using externally developed and industry standard taxonomies for product categorizations in order to manage and plan their inventory. Amazon Business’s vision is to support a diverse pool of taxonomy-based product categorizations so that it serves as the premier destination for these customers.

As an Ontologist, you will work on a global team of knowledge builders to help us consistently interpret these taxonomies (like UNSPSC, E-Class, etc.) and create a unified taxonomy to help translate product categorizations across taxonomies to meet the diverse needs of customers in the B2B space. Moreover, you will help create crisp guidelines on how to categorize products using a combination of human in the loop systems. You will also be responsible for driving the opinion on how to evolve these taxonomies to meet the growing needs of our customers.
