Senior Data Engineer - Product Engineering

What You'll Do : 🌍 About the Team

The Performance Measurement team plays a key role in helping advertisers understand the true impact of their campaigns run with Criteo.

Our mission is to measure, analyze, and surface campaign performance insights to both internal and external stakeholders.

To achieve this, we work with massive-scale data — leveraging Criteo’s rich shopper graph as well as data from trusted external measurement partners.

We collaborate closely with Product Managers and multiple R&D teams, including those building Criteo’s machine learning models and internal & external reporting solutions.
