• Data Collection Infrastructure: Ensure high-quality client-side instrumentation to support attribution, analytics, and retargeting
• Privacy & Compliance: Respect GDPR/CCPA and user consent through proper tracking logic and conditional firing
• Cross-team Collaboration: Work closely with backend, data, and product teams to ensure end-to-end tracking integrity and accuracy

• Understanding of real-time bidding, auctions, and header bidding
• Familiarity with identity resolution, UTM/cookie handling, or postback flows
• Contributions to analytics, instrumentation, or event-tracking frameworks
