Founding Marketer at S3 Sensitivity Science
1 in 3 people suffer from tooth sensitivity, yet the market leader hasn't innovated in decades. S3 Sensitivity Science is changing that with proprietary technology that clinically outperforms the incumbent. Led by veteran D2C operators who have scaled multiple subscription brands, this is a rare chance to join as a Founding Marketer. You'll own the entire growth engine from scratch—performance, creative, and CRM—with a founding team equity stake and the backing of the science leaders who originally built Sensodyne. If you thrive on high-intensity builds and move fast, this Camden-based role is your next big chapter.
