What You’ll Do

This role sits within the Data Analytics (Analytics, Stewardship, Capabilities) team, part of Media Analytics.

We are seeking an observant, meticulous, and technically fluent problem solver who thrives at the intersection of data, media operations, and technology. The focus of this role is Platform Management – supporting paid media optimization, attribution, and analytical initiatives through day-to-day platform operations, data asset management, and related technical integrations and projects.

You’ll navigate a complex and fragmented ecosystem of media and data platforms – each with its own UX, data model, and vocabulary – to ensure information is accurate, consistent, and actionable. Success requires curiosity, exceptionally structured thinking, and the ability to connect business objectives with technical realities.

This role demands a rare combination of operational experience and technical acumen. You should be comfortable managing and troubleshooting systems, understanding how data flows across platforms, and translating between the perspectives of marketing, analytics, development, and governance teams. You’ll help shape and manage our data assets across multiple campaign operations–facing platforms, influence platform configurations, partner on data integrations, and contribute to governance frameworks that ensure readiness, quality, and consistency across environments.
