Company Description: S3 Sensitivity Science - D2C healthcare disruptor founded by Skin + Me and Life Supplies alumni.

Job Description: As the first marketing hire, you will build the entire growth engine from scratch for a proprietary oral healthcare brand.

  • Gain true founding level equity and total autonomy to build the marketing playbook and function without the constraints of legacy corporate structures.
  • Work in an AI native environment where speed and high agency execution are the default, supported by proprietary formulation technology that outperforms the current market leader.

What you will do:

  • Architect and execute the full stack growth strategy across Meta/paid social, email/SMS flows, and Shopify CRO to drive the Summer 2026 launch.
  • Own the commercial North Star metrics including CAC, ROAS, and LTV, translating marketing activities into sustainable revenue and unit economic success.
  • Scale the brand's digital presence by identifying and exploiting high growth channels and creating content that resonates with a younger, digitally native audience.

The ideal candidate:

  • 2-3+ years of hands-on D2C growth experience at a UK challenger brand (e.g., Huel, Surreal, or Grind) or a fast-paced performance agency.
  • Founder minded operator who is AI native and moves fast without needing a brief, optimized for equity upside and long term value creation.
  • Deeply analytical with a mastery of paid social mechanics and a relentless drive to absorb D2C marketing crafts and emerging industry trends.
