Company Description
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.
Job Description
As a Principal Data Scientist, you shape high‑impact, client‑relevant Data Science concepts and ensure strategic coherence across teams and domains. This role is a perfect playground for highly experienced, concept‑driven minds who enjoy influencing direction, clarifying complexity, and shaping how Data Science creates value at scale.
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.
You ensure that high‑impact Data Science initiatives across currency and outcome products are well‑framed, feasible, client‑relevant, and decision‑ready before they enter delivery structures, reducing conceptual noise while increasing business impact.

Client, Market & Growth Impact
- Contribute to client pitches, tenders, and growth initiatives
- Support market expansion
- Ensure concepts scale across markets and media contexts while remaining compatible with existing currency principles
