Happy Mammoth is a fast-growing natural food technology company selling across the US, Australia, and Europe. We formulate, produce, and market gut, digestive, and microbiome health supplements—and performance marketing is a key driver of our growth.

This is not a brand or content position. It is firmly focused on paid acquisition and performance creative. We’re looking for a Creative Strategist with a direct-response mindset—ideally someone who began as a copywriter and progressed into performance creative strategy.

Part-time freelance contractor
B2C / DTC Experience Required
EU hours (GMT)

Experience in supplements/health is a strong advantage.

This role is about what drives conversions—not what just looks good.

What you’ll do

• Own performance creative strategy for paid media (Meta-focused)
• Create angles, hooks, messaging frameworks, and iteratively improve them
• Turn data (CTR, CPA, CVR, ROAS) into creative decisions
• Develop and refine creative testing roadmaps
• Brief and collaborate with copywriters, editors, and designers to iterate
• Review winning vs. losing creatives and scale what works
• Improve performance through structured experimentation

What we’re looking for

• Proven experience in performance marketing creative
• Strong copy background (ads, hooks, messaging—not just ideas)
• Hands-on experience working with media buyers
• Confidence in owning outcomes, not just tasks
• Clear understanding of direct-response psychology
• Ability to move quickly, test frequently, and iterate

Requirements

• Senior-level experience in performance creative and/or direct-response copywriting
• Proven familiarity with 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 work independently in a fast-paced remote setting
• Availability during EU working hours (GMT)

Why work at 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 arrangement—work around your schedule
