Original job description

The vision of the Product Knowledge Ontology Team is to provide a standardized, semantically rich, easily discoverable, extensible, and universally applicable body of product knowledge that can be consistently utilized across customer shopping experiences, selling partner listing experiences and internal enrichment of product data. We aim to make product knowledge compelling, easy to use, and feature rich. Our work to build comprehensive product knowledge allows us to semantically understand a customer’s intent – whether that is a shopping mission or a seller offering products. We strive to make these experiences more intuitive for all customers.

As an Ontologist, you work on a global team of knowledge builders to deliver world-class, intuitive, and comprehensive taxonomy and ontology models to optimize product discovery for Amazon web and mobile experiences. You collaborate with business partners, data science and engineering teams to deliver knowledge-based solutions to enable product discoverability for customers. In this role, you will directly impact the customer experience as well as the company’s product knowledge foundation.

About the team Our team has a global presence: we celebrate diverse cultures and backgrounds within our team and our customer base. We are committed to furthering our culture of inclusion, offering continuous access to internal affinity groups as well as highlighting diversity programs. We care about your career growth, from your initial company introduction and training sessions, to continuous support throughout your entire career at Amazon. We recognize each team member as an individual, and we will build on your skills to help you grow. We have a broad mix of experience levels and tenures, and we are building an environment that celebrates knowledge sharing. Basic qualifications

Bachelor's degree or equivalent
Degree in Library Science, Information Systems, Linguistics or equivalent professional experience
3+ years of relevant work experience working in ontology and/or taxonomy roles
Proven skills in data retrieval and data research techniques
Ability to quickly understand complex processes and communicate them in simple language
Ability to communicate knowledge-based requirements and needs to engineering and retail teams
Familiarity with Semantic Web technologies (RDF/s, OWL), query languages (SPARQL) and validation/reasoning standards (SHACL, SPIN)
Detail-oriented problem-solving, ability to work in fast-changing environment and manage ambiguity
Proven track record of strong communication and interpersonal skills Preferred qualifications
Master’s degree in Library Science, Information Systems, Linguistics or other relevant fields
Experience building data models in the e-commerce and semantic search spaces
