Founding Marketer - Head of Growth (£50k–£80k + Equity) at S3 Sensitivity Science
About the role
Join S3 Sensitivity Science as their first marketing hire and build a D2C powerhouse from the ground up. Founded by the experts behind Skin + Me and Life Supplies, S3 is set to disrupt the massive oral healthcare market with proprietary science that outperforms legacy brands like Sensodyne. This isn't a role for a traditional manager; it's for a high agency 'wannabe founder' who wants to own the entire growth engine—from Meta ads to unit economics. With a proven playbook, significant founding equity, and a London based team that moves at lightning speed, this is your chance to turn a clinical breakthrough into a household name.
