Creative Strategist (Freelance, Part-time)
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.

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)
