Creative Strategist (Freelance, Part-time)

Bucharest, Bucharest, Romania

Part Time

Experienced

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
