Martech Engineer

Summary

ElevenLabs is an AI research and product company transforming how people interact with technology. The Martech Engineer will own the company’s measurement layer, including tag management, tracking and attribution scripts, server-to-server conversion tracking, consent enforcement, and monitoring. The role partners closely with paid marketing, frontend engineering, data engineering, and product engineering to ensure accurate and performant conversion measurement.

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

Skills

• • Strong JavaScript/TypeScript, comfortable working in both frontend code and a production application codebase
• • Hands-on experience with Google Tag Manager, including server-side GTM, and at least one conversion API (Meta CAPI, Google Enhanced Conversions, or similar) implemented server-to-server
• • Experience debugging attribution discrepancies end to end: pixel vs server deduplication, UTM conventions, event schema design
• • Solid understanding of web performance and how to add tracking without degrading Core Web Vitals
• • Working knowledge of consent and privacy requirements (Consent Mode v2, regional restrictions) and SQL for validating tracking data in the warehouse
• This role is remote and can be executed globally
• • CDP experience (Segment, RudderStack, Snowplow)
• • Product analytics tools (GA4, Amplitude, PostHog) and dbt
• • Next.js experience
• • Exposure to incrementality testing or media mix modelling
