Social Advertising Specialist

We are looking for a Social Advertising Specialist to help us scale customer acquisition through high-performing paid social campaigns.

In this role, you will build, test, and optimize campaigns across channels such as Instagram, Facebook, TikTok, LinkedIn, and other relevant platforms. Your work will directly contribute to qualified demand, stronger creative performance, better conversion quality, and improved marketing efficiency.

This is a good fit for someone who combines performance marketing expertise with creative judgment, analytical thinking, and a structured experimentation mindset.

Wellis is a fast-growing healthtech scale-up reinventing healthcare. We are building the first truly integrated health platform in the Netherlands, offering on-demand care for everyday health needs such as weight loss, hair loss, sexual health, and more.

Our platform covers the full journey: from diagnosis and medical assessment to prescription and delivery at home. By combining medical expertise, technology, and data, we make healthcare smarter, more accessible, more personal, and easier to use.

We are growing quickly, which means we are building the structures, teams, products, and processes that will help us scale responsibly. You will join an ambitious, international team where ownership is encouraged, collaboration is key, and impact is visible from day one.

As our Social Advertising Specialist, you will join our Marketing team and report directly to the Performance Marketing Lead.

You’ll collaborate cross-functionally—with Content, Design, Data, CRM, Medical, and Customer Care—to ensure our campaigns are engaging, compliant, and tightly integrated into the customer journey.

Your immediate focus will be optimizing paid social performance, building a structured creative testing framework, and refining funnel strategies. Over time, you’ll help establish a scalable, data-backed performance playbook. Your ultimate goal is simple: drive high-quality customer acquisition while keeping CAC, POAS, and Profit contribution on track.
