People Operations Specialist

Introduction

We're looking for a part-time (24h-32h) People Operations Specialist to keep everything behind the scenes running smoothly — from contracts and payroll to onboarding and employee support.

You'll be the operational heartbeat of our People & Culture function, making sure everything is structured, compliant, and human.

This is an exciting opportunity for someone early in their HR career who loves organizing, improving systems, and being the go-to person everyone relies on.

About Wellis

Wellis is a young, fast-moving healthtech scale-up with a clear mission: combine medical expertise, technology, and data to make healthcare smarter, more efficient, and more personal.

We started only 2 years ago, but experienced amazing traction and success leading us to the point where we are now creating structures, expanding teams with top talent, and setting up our product for growth.

We're focused on lowering the barriers to care, especially for health concerns people don't always feel comfortable seeking help for. Our treatment portfolio is expanding rapidly, and our ambition is to build long-term, digital-first solutions that support people across different stages of their health journey.

You'll join an ambitious, international team where ownership is encouraged, collaboration is key, and impact is visible from day one. We're opening our new office in Rotterdam this year, where the team will meet 1–2 days per week to brainstorm, build, and grow together.

About the Role

As our People Operations Specialist, you are the backbone of all People & Culture operations at Wellis. With your precision, empathy, and sense of structure, you make sure that contracts, payroll, employee data, and onboarding all run seamlessly.

You'll ensure our people processes are compliant and efficient, while keeping a strong focus on the human side of work.

Your efforts will free up the rest of the team to focus on culture, growth, and development — and you'll help shape the employee experience from day one.

You'll report directly to the People & Culture Lead and collaborate closely with our leadership, finance, and recruitment teams.
