Job description

Happy Mammoth is a rapidly expanding natural food tech company with a presence in the United States, Australia, and Europe. We are experts in crafting, manufacturing, and promoting gut health foods, digestive aids, and microbiome-focused supplements. Our mission is to empower clients to embrace lasting health transformations and rediscover vibrant living.

We are currently looking for a UI/UX Designer (focus on UI with UX experience) to join our vibrant, diverse team of international innovators, where creativity knows no bounds.

As our UI/UX Designer, you'll shape how customers experience our website and campaigns — designing pages and creatives that are visually polished, intuitive to navigate, and built to convert. You'll bring strong UI craft paired with a solid UX foundation, turning briefs and rough concepts into high-quality designs that balance beautiful visual design with real business impact.
