About the role

ElevenLabs is seeking an engineer to own their measurement layer, including tag manager setup, tracking and attribution scripts, and server-to-server conversion tracking. This role sits at the intersection of frontend engineering, data engineering, and marketing, ensuring accurate data for paid acquisition budgets. You will be responsible for maintaining tracking health, optimizing performance, and building monitoring systems to ensure data integrity.

Responsibilities

  • Own our tag manager setup end to end, including the server-side GTM container, and review any changes other teams want to make
  • Work with the paid marketing team daily: fix tracking bugs, set up tracking for new landing pages and campaigns, and debug discrepancies between platform-reported conversions and our internal data
  • Build and maintain server-to-server conversion tracking (Meta CAPI, Google Enhanced Conversions, and similar) and validate pixel vs server deduplication
  • Improve tracking script performance and correctness, keeping script impact on pagespeed and Core Web Vitals within budget
  • Make sure consent handling and regional restrictions are correctly enforced across markets
  • Define event schema and UTM conventions, and document them so tracking for new campaigns is correct by default
  • Build monitoring and alerting for the measurement stack so we catch broken tracking within hours, not weeks
  • Review PRs that add conversion events to the main app, and work with product engineering on tracking integrations
