Technology is central to everything we do, and a key aspect of the evolving technology organization is to be aware of the emerging technologies and their applications to Argus services.

The Head of Ontology leads the strategy, design, and implementation of semantic data models, knowledge graphs, and taxonomies to enable AI, data integration, and search capabilities. You will bring a passion for data in all its forms, a pragmatic approach to achieving demonstrable results, and the ability to adapt to different perspectives and levels of data maturity.

This executive role involves overseeing ontology governance, collaborating with stakeholders (data engineering, machine learning), and driving the adoption of industry standards (RDF, OWL) to solve complex, unstructured data challenges.

Leading a small, focused team, you will collaborate with technology, data, and business functions across the company to establish a solid, interoperable data foundation for all.
