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.

Top Reasons to Work at Happy Mammoth

• A Strong Salary Package: We'll pay you well because your skills and hard work deserve the best.
• Paid Holidays: Take all the time you need to binge-watch your favorite shows, explore new places, or just relax. It's on us!
• Work from Anywhere: Whether it's your couch, a trendy café, or a co-working space by the beach (lucky you), the world is your office.
• Join a Vibrant Team: Teamwork makes the dream work! You'll be part of a global crew that's as talented as they are friendly.
• Flexible Working Hours: Manage your schedule how it fits best for you — late-night productivity, early morning hustle, or everything in between.
• Opportunities for Growth: We'll give you free books, courses, and all the resources you need to level up your skills and keep excelling.
• Dynamic Work Environment: No two days are the same here. Embrace new challenges and excitement every day in a diverse, fast-paced workplace.
• Make a Difference: Join our mission to help clients improve their health and live more fulfilling lives. It's not just a job - it's a chance to make a real impact!

Key Points

• This is a full-time, fully remote contractor role.
• We are seeking someone preferably with a background in B2C/e-commerce or DTC design.
• Although the role is remote, the candidate must be available during EU hours (GMT).

This role is embedded within our e-commerce team and is dedicated to designing and optimizing our DTC storefront — not general product or brand design.

Key Responsibilities

• Design and improve product pages, ensuring they are visually compelling, clear, and easy to navigate.
• Create campaign creatives that communicate our message clearly and encourage users to take action.
• Redesign and improve existing areas of our website, identifying opportunities to improve the user experience, engagement, and conversion.
• Take briefs, ideas, and campaign concepts and turn them into polished, high-quality designs.
• Use your UX knowledge to determine where key information, CTAs, trust elements, benefits, and other conversion elements should be placed.
• Think through the user journey when designing new pages, making sure the flow feels natural and without friction.
• Help keep our visual design consistent across the website and different campaign experiences.
• Adapt and improve designs quickly based on feedback and business priorities.
• Ensure designs are responsive and work well across desktop and mobile.

Requirements

• Proven experience as a UX/UI Designer, with a strong portfolio of digital and web design work — specifically for e-commerce or direct-to-consumer (DTC) brands.
• Required: minimum 2+ years designing for e-commerce or DTC brands — this is a must‑have, not a nice‑to‑have. Experience in health, wellness, or supplements is a strong plus.
• Strong UI design skills, with excellent attention to detail and a high standard for visual quality.
• Good understanding of UX principles and conversion‑optimised design.
• Ability to balance strong visual design with user experience and business goals.
• Good understanding of conversion principles and how design can influence user behavior and decision‑making.
• Experience designing responsive websites for both desktop and mobile.
• Strong proficiency in Figma.
• Ability to take a concept or rough brief and turn it into a polished, well‑thought‑out design.

Location

Please note: due to operational constraints, we are unfortunately unable to consider candidates based in the US, the UK, or the Netherlands at this time.

Application Requirements

CVs must be submitted in English. Applications submitted in other languages will not be considered.
