About the Role

At Nu, paid media is one of our most strategic growth investments. As a Media BI Specialist, you'll be responsible for measuring, analyzing, and explaining the real impact of those investments.

You'll join the Media team as an analytics-first role, focused on performance measurement, incrementality, and ROI across the full funnel. Your work will connect paid media data with product usage and financial outcomes, helping define official metrics and guide investment decisions.

It's a measurement and decision-support role, requiring strong analytical depth, ownership of data and dashboards, and the ability to turn complex analyses into clear recommendations for leadership.

Experimentation & Incrementality

• Design, structure, and analyze A/B tests, holdouts, and geo experiments.

• Inform decisions to scale, optimize, or pause paid media investments.

Data Governance, Audiences & Reporting

• Guarantee consistency, reliability, and trustworthiness of paid media and business data.
• Own the definition of official media and marketing metrics, including internal KPIs such as BHT.
• Be responsible for audience governance, including targeting audiences, control groups, test bases, and exclusions used across media platforms.
• Define standards for dashboards and reporting, ensuring a single source of truth.
• Produce executive-level reports with clear insights and recommendations for senior leadership.
