Principal Data Scientist | Media Measurement (MM) in London

NIQ’s Media unit delivers audience measurement solutions across TV, radio, digital, and cross-media platforms for currency clientele, including broadcasters, advertisers, agencies, and regulators. A core component of our measurement approach is panel-based methodologies, leveraging household and individual panels to ensure accurate, representative audience insights. Census data is integrated across several solutions to further enhance measurement quality.

As a Principal Data Scientist, you shape high‑impact, client‑relevant Data Science concepts and ensure strategic coherence across teams and domains.

You will work on analytics, Data Science and AI topics across our Media pillar, including Media Measurement, Audience Activation, and Performance. The focus of the role is strongly conceptual and influence‑heavy: from innovation seeds and scalable target pictures to client pitches, tenders, and strategic roadmaps.
