Introduction

The creative output at Wellis is growing fast — across social channels, campaigns, and the content we share with customers to support their health journey. To strengthen our design capacity, we're looking for a Junior Designer. In this role, you'll create engaging social content (organic/paid) for channels like Instagram, Facebook, YouTube, and TikTok, that drive traffic to our website. You'll also help turn expert input from our doctors and dieticians into clear, on-brand visuals for nutrition guides, exercise guides, e-books, and other customer-facing materials. Working closely with our Lead Designer Mike, you'll get hands-on guidance and feedback while developing your skills and making real impact.

About Wellis

At Wellis, our mission is Breaking habits for healthier, happier lives. We exist to genuinely help people. We do this by offering medical solutions that make a real difference, especially in areas where there is still a lot of taboo.

We focus on conditions like overweight, hair loss and sexual health. These are sensitive topics, but we believe people deserve honest, accessible and high-quality care. Our goal is to break taboos and help people feel better about themselves.

So far, we have helped over 45,000 customers and we are proud of our 4.7 Trustpilot score, based on nearly 1,900 reviews. Customer satisfaction is extremely important to us. We work hard every day to keep this score high by improving every touchpoint in the customer journey. This role directly contributes to that mission.

Our office is located in the heart of Rotterdam, at a premium spot with views over the Coolsingel. We are within walking distance of Rotterdam Central Station and metro stop Stadhuis. The area is full of gyms, cafés, supermarkets and bars.

You’ll work from one of the highest buildings in the city, with great views, a daily catered lunch, and a friendly, ambitious marketing team with different skills and backgrounds.

About the Role

As a Junior Designer, you'll help bring Wellis' brand and medical expertise to life through strong, on-brand visuals across multiple channels. You'll create social content (stills & videos) for platforms like Instagram, Facebook, YouTube, and TikTok, and design supportive customer materials such as nutrition and exercise guides, e-books, and other resources that help people improve their health and weight-loss journey.

You'll translate input from doctors, dieticians, and other experts into clear, engaging designs and illustrations, and you'll also support growth by creating social and display ads that drive traffic to our website. In addition, you may help with webinar visuals and editing or creating FAQ-style video content with our doctors. You'll work closely with our Lead Designer, Mike, who will guide you, support your development, and provide regular feedback.

Key Responsibilities

• Create and design social media content for Instagram, Facebook, YouTube, and TikTok (and support expansion to new channels).

• Develop visual assets for nutrition guides, exercise guides, e-books, and other customer-facing documents that support weight-loss and healthy lifestyle goals (e.g., sleep, stress, and more).

• Work closely with Lead Designer Mike to align on briefs, follow the house style and brand guidelines, and iterate based on feedback.

• Ensure high-quality output across formats by maintaining attention to detail, consistency, and strong visual storytelling.
