  Analyze large‑scale datasets to extract insights on user consent rates, non‑personalized ad inventory, and signal resilience, directly influencing the roadmap for privacy‑safe monetization.
• Product Experimentation:
  Design and analyze A/B tests to validate new targeting features and privacy‑enhancing technologies (PETs).
• Reporting & Monitoring:
  Develop dashboards to monitor the health of targeting systems and the stability of ad delivery in a changing regulatory environment.

• Proficiency in SQL and at least one scripting language (preferably R/Python).
• Experience in using data visualization tools.
• Experience with large data sets and distributed computing (Hive/Hadoop) is a plus.
