Full job description

Happy Mammoth is a fast-growing natural food tech business selling across the US, Australia, and Europe. We formulate, produce, and market gut, digestive, and microbiome health supplements — and performance marketing is a core growth driver for us.

This is not a brand or content role. It sits squarely in paid acquisition and performance creative. We're looking for a Creative Strategist with a direct-response mindset — ideally someone who started as a copywriter and evolved into performance creative strategy.

Part-time freelance contractor 
B2C / DTC experience required
EU hours (GMT)
Supplements / health a strong plus

This role is about what converts, not what "looks good."

What you'll actually do

  • Own performance creative strategy for paid media (Meta-focused)
  • Develop angles, hooks, messaging frameworks, and iterations
  • Translate data (CTR, CPA, CVR, ROAS) into creative decisions
  • Build and refine creative testing roadmaps
  • Brief and iterate with copywriters, editors, and designers
  • Analyze winning vs losing creatives and scale what works
  • Continuously improve performance through structured experimentation

What we're looking for

  • Proven experience in performance marketing creative
  • Strong copy background (ads, hooks, messaging — not just concepts)
  • Hands-on experience working with media buyers
  • Comfort owning results, not just deliverables
  • Clear understanding of direct-response psychology
  • Ability to move fast, test often, and iterate

Requirements

  • Senior-level experience in performance creative and/or direct-response copywriting
  • Proven exposure to paid media environments (Meta experience required)
  • Strong understanding of conversion-focused creative and testing
  • Fluency in English (CVs must be submitted in English)
  • Ability to operate independently in a fast-paced, remote setup
  • Available during EU working hours (GMT)

Why Happy Mammoth

  • Competitive compensation aligned with senior performance roles
  • Fully remote with clear ownership and accountability
  • Opportunity to work on high-impact, high-scale performance campaigns
  • Flexible part-time engagement — work around your schedule
