Your job is to ensure that our data flows are accurate, privacy-compliant, and optimized to support all growth initiatives across the Ageras brands.You’ll serve as the bridge between marketing strategy and technical implementation—one day collaborating with a product manager to track a new feature, the next working with legal to ensure GDPR-compliant solutions.

• Power campaign performance: Build conversion tracking and enable smart bidding via server-side integrations (CAPI, Google Enhanced Conversions, TikTok, Snap, etc.).
• Ensure data quality & attribution: Standardize UTMs, implement deduplication, and maintain attribution logic for accurate reporting.
• Embed privacy & compliance: Implement Consent Mode v2, integrate CMPs, and ensure GDPR-compliant tracking practices.
• Enable cross-platform visibility: Support mobile/app tracking with Firebase or AppsFlyer and align it with web
• Drive cross-team alignment: Collaborate with growth marketers, legal, data, and product teams to translate business needs into robust tracking plans.
