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.
