Marketing Data Scientist

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 $22B - multiples of 11, always.

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. IOI medalists and ex-founders. 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. 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.

ABOUT THE ROLE

We're looking for a Data Scientist to support ElevenLabs' offline media and strategic marketing bets: from OOH billboards to niche sponsorships and experimental brand campaigns. You'll build the frameworks that tell us whether a channel with no click to track is actually working, partnering closely with Marketing and the Growth Data team.

- Design and run measurement for offline / out-of-home campaigns: geo holdout tests, matched-market tests, media mix modelling and incrementality studies.

- Partner directly with Marketing leadership on which niche channels, markets or formats to test next, and size the bet.

- Build models that combine offline spend data with digital and product signals into one coherent view of marketing effectiveness.

- Work alongside the Growth Data team's digital marketing data scientists to keep offline and online measurement consistent.

REQUIREMENTS

Demonstrated experience measuring marketing effectiveness, ideally including offline, brand or hard-to-track channels (OOH, TV, podcast, sponsorship, events).

- Strong SQL and Python, with experience in causal inference, media mix modelling or incrementality testing.

- Comfort designing measurement without a clean click-level signal, and communicating uncertainty honestly.

- Strong stakeholder management with Mar
