Bloomberg runs on data. Our products are fuelled by powerful information. We combine data and context to paint the whole picture for our clients, around the clock – from around the world. In Data, we are responsible for delivering this data, news and analytics through innovative technology – quickly and accurately. We apply problem-solving skills to identify innovative workflow efficiencies, and we implement technology solutions to enhance our systems, products and processes - all while providing platinum customer support to our clients. As part of the Data Management Lab (DML) department, we're responsible for supporting the development, enablement, and implementation of data management best practices that enable the delivery of “ready-to-use” data.

What’s the role?

As a Senior Ontologist, you will be pivotal in maintaining and expanding the knowledge representations at Bloomberg. Specifically, you will use ontologies, taxonomies, and other semantic foundational components to enhance data interoperability, metadata management, artificial intelligence applications, and more! The day-to-day will vary; some days you may be meeting with domain experts to develop competency questions, while other days you will be adding coverage to Bloomberg’s central ontology. Your work will touch a multitude of domains across Bloomberg, covering many departments like Data, Product, and Engineering.
