About ElevenLabs
ElevenLabs is an AI research and product company transforming how we interact with technology. We launched in January 2023 with the first human-like AI voice model. Today, we serve millions of users and thousands of businesses - from fast-growing startups to large enterprises like Deutsche Telekom and Meta. Our investors are some of the world's most prominent, including Andreessen Horowitz, ICONIQ Growth and Sequoia. We've raised $781M in funding and our last valuation was $11B.
We have expanded from voice into three main platforms:
- ElevenAgents enables businesses to deliver seamless and intelligent customer experiences, with the integrations, testing, monitoring, and reliability necessary to deploy voice and chat agents at scale.
- ElevenCreative empowers creators and marketers to generate and edit speech, music, image, and video across 70+ languages.
- ElevenAPI gives developers access to our leading AI audio foundational models.
Everything we do is the result of the creativity and commitment of our team - builders doing the best work of their lives. We are researchers, engineers, and operators. If you want to work hard and create lasting positive impact, we want to hear from you.
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.
- AI first: We use AI to move faster with higher-quality results.
- Excellence everywhere: Everything we do should match the quality of our AI models.
- Global team: We prioritise your talent, not your location.

- Co-working: We offer a monthly co-working stipend if you’re not located near one of our main hubs.
About the role:
ElevenLabs spends meaningfully on paid acquisition, and that spend is only as good as the data behind it. We are looking for an engineer to own our measurement layer end to end: the tag manager setup, the tracking and attribution scripts on our sites, and the server-to-server conversion tracking that feeds our ad platforms.
Day to day you will work closely with the paid marketing team: fixing tracking bugs, setting up tracking for new landing pages and campaigns, and debugging discrepancies between platform-reported conversions and our internal data. Longer term, you will define how tracking should properly work here and build the monitoring so we catch breakage in hours, not weeks.
This role sits between frontend engineering, data engineering, and marketing. You will add and improve tracking scripts without hurting pagespeed, keep our server-side GTM container healthy, make sure consent and regional restrictions are correctly enforced, and ensure the right channels get credit for the right conversions. Your work directly decides how a large paid budget gets allocated.
What you will 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 PRs that add conversion events to the main app, and work with product engineering on tracking integrations.
Requirements:
- 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.
Bonus:
- CDP experience (Segment, RudderStack, Snowplow).
- Product analytics tools (GA4, Amplitude, PostHog) and dbt.
- Next.js experience.
- Exposure to incrementality testing or media mix modelling.
Growth potential:
We believe in hiring the best talent in the world to make an impact in the right role at the right time. At ElevenLabs, strong performance creates opportunities for growth.
Location:
This role is remote and can be executed globally. If you prefer, you can work from our offices in London, New York, Madrid, Warsaw and many more.
We are an equal opportunity employer and do not discriminate on the basis of race, religion, national origin, gender, sexual orientation, age, veteran status, disability or other legally protected statuses.
