About The Position

HydroPeptide is seeking a Senior Growth Marketing Manager to drive profitable customer acquisition and repeat purchase for its digital business. This hands-on senior role owns paid media strategy and budget across Meta, Google, TikTok, and emerging channels, as well as the email and SMS program. The role is accountable for growing the customer base at a sustainable customer acquisition cost while balancing strategy, execution, testing, and team leadership.
