Marketing Data Scientist

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 Marketing / Brand leadership, able to turn a strategic question into a testable plan.

• Structured thinker comfortable with ambiguity: this is a newer, less-defined function.

• Experience specifically with OOH, billboard or experiential campaign measurement.

• Experience with media mix modelling tools or frameworks (Robyn, Recast, LightweightMMM or similar).

• Experience partnering with brand or creative teams on niche or unconventional marketing bets.

• 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.

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.

This role is remote-first, so it can be executed from anywhere in Europe or the US East Coast, with the ability to operate in CET / ET timezones required. If you prefer, you can work from our offices in London, Warsaw, Dublin or New York.
