Our Mission You call. You wait. You call again. In every other part of your life, you book in seconds. In healthcare, you’re blocked. We’re here to give power to the patient. For nearly 20 years, we’ve built the leading healthcare marketplace - helping tens of millions of people find and book the care they need. Now, we’re going further: building our infrastructure beyond Zocdoc’s marketplace to power access to care wherever patients search, from provider websites and insurance directories to search engines, AI platforms, and more. Healthcare still lacks something every other major consumer industry takes for granted: a seamless way to go from seeking to getting . We don’t want to own the front door to care; there isn't one. We want to make sure all of those doors open when patients are knocking. Fixing healthcare starts with fixing access to it. And we're still just getting started. Your Impact on our Mission Zocdoc's most important asset is our people. As Director, Marketing Data Science, you'll own the measurement strategy that determines how Zocdoc invests in reaching patients and providers. Your work will directly shape how we allocate marketing resources across B2C patient acquisition, B2B provider marketing, lifecycle, and brand — ensuring every dollar drives measurable impact on our mission to give power to the patient. This is a greenfield opportunity. You'll define what a rigorous, unified marketing measurement function looks like at Zocdoc — then build it. You'll enjoy this role if you are… Personally motivated by solving hard measurement problems where the right answer requires building new methods, not just applying existing ones. The kind of data scientist who builds models, not just reviews them. You want to be hands-on with MMM, MTA, and incrementality testing — not managing from a distance. Genuinely curious about the frontier of marketing measurement. You follow how the field is evolving (privacy changes, signal loss, new c
