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. Working directly with founders who scaled previous ventures to £70M+ ARR, you’ll own the full funnel—from paid social and CRO to retention—disrupting a stagnant market dominated by Sensodyne.
Location: London, UK
Why this role is remarkable: Partner with a proven founding team including the co‑founder of Skin + Me to launch a clinically superior product into a massive global category. 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.
