HOW WE WORK
- High-velocity: Rapid experimentation, lean autonomous teams, and minimal bureaucracy.
- Impact not job titles: We don't have job titles. Instead, it's about the impact you have. No task is above or beneath you.
- AI first: We use AI to move faster with higher-quality results. We do this across the whole company - from engineering to growth to operations.
- Excellence everywhere: Everything we do should match the quality of our AI models.
- Global
team: We prioritize your talent, not your location.
WHAT WE OFFER
- Innovative culture: You'll be part of a generational opportunity to define the trajectory of AI, surrounded by a team pushing the boundaries of what's possible.
- Growth paths: Joining ElevenLabs means joining a dynamic team with countless opportunities to drive impact - beyond your immediate role and responsibilities.
- Learning & development: ElevenLabs proactively supports professional development through an annual discretionary stipend.
- Social travel: We also provide an annual discretionary stipend to meet up with colleagues each year, however you choose.
- Annual company offsite: Each year, we bring the entire team together in a new location - past offsites have included Croatia and Italy.
- Co-working: If you're not located near one of our main hubs, we offer a monthly co-working stipend.
What you'll do
- 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 pull requests that add conversion events to the main app, and work with product engineering on tracking integrations.
- Maintain a deep understanding of marketing attribution models so data matches the expectations of stakeholders.
- Implement robust testing strategies for tracking flows to prevent regressions in production.
Requirements
- Strong JavaScript/TypeScript, comfortable working in both frontend code and a production application codebase.
- Hands-on experience with Google Tag Manager and server-side tag management implementations.
- Proven ability to debug tracking discrepancies across platforms such as Meta and Google Ads.
- Solid understanding of web performance metrics and how tracking scripts affect Core Web Vitals.
- Experience with consent management platforms and compliance with regional data regulations.
- Familiarity with HTTP protocols, server-side event streaming, and webhook integrations.
- Strong attention to detail and the ability to validate data integrity across complex pipelines.
- Ability to translate ambiguous requirements into concrete tracking specifications and documentation.
Nice to have
- Experience with conversion APIs and server-side analytics platforms.
- Knowledge of marketing attribution models and incrementality testing.
- Background in working with enterprise-scale advertising budgets and complex campaigns.
