Job description

Introduction

The digital customer journey at Wellis is growing rapidly and becoming more complex. To take it to the next level, we’re looking for a Digital Experience & CRO Specialist. You will own everything that touches our online journey — from the very first visit to subscription management. With your knowledge of data, psychology, and design, you’ll make Wellis more intuitive, personal, and conversion-driven. It’s time for an experienced specialist to raise our digital experience to benchmark level in the healthcare world.

About Wellis

Wellis is a fast-growing healthtech scale-up that is reinventing one of the most traditional sectors: healthcare. What started just three years ago has already grown into a company with tens of thousands of customers, and we are only at the beginning. By combining medical expertise with technology and data, we make healthcare smarter, more efficient, and more personal.

Our mission is to improve everyday lives by making care accessible, personal, and seamless. Through our platform, people can take control of their health journey with trusted medical support, smart digital tools, and tailored programs. We move fast, challenge conventions, and build solutions that truly make an impact, because we believe better healthcare should be within everyone’s reach.

About the Role

As a Digital Experience & CRO Specialist, you’ll be responsible for the entire digital customer journey. You’ll identify friction points, set up experiments, and work closely with UX, content, data, and development. Your job is to ensure the Wellis site not only converts, but also radiates trust and ease of use.

Key Responsibilities:

  • Full ownership of the digital customer journey — from first visit to retention.

  • Identify friction points using data, session replays, and customer feedback.

  • Set up, manage, and analyze A/B and multivariate tests.

  • Build an experiment roadmap and share learnings across the team.

  • Improve onboarding, checkout, and consult flows in collaboration with design & tech.

  • Initiate user research and translate insights into concrete improvements.

  • Build dashboards and reports for conversion and UX KPIs.

  • Act as sparring partner for marketing, tech, data, and C-level on digital strategy.

About the Team

You’ll report directly to our CMO, Robert, who brings extensive experience from companies like Coolblue and Betcity. You’ll work closely with specialists in content, design, performance marketing, and data — with plenty of room to take initiative yourself. As we’re also hiring an Email Marketer, the digital domain is growing fast, and you’ll have the opportunity to play a key role in shaping a strong digital team.

A Week in the Life @ Wellis

  • Monday: Analyze Hotjar sessions and discuss new test ideas with the designer.

  • Tuesday: Launch an A/B test for the checkout flow and share hypotheses during the marketing sync.

  • Wednesday: Dive into cohort analyses and retention patterns with the Data Lead.

  • Thursday: Run usability tests and present findings to marketing and tech.

  • Friday: Wrap up the week with a C-level update on learnings, winning variants, and new experiments.

Job requirements

Who You Are

  • At least 4 years of experience in CRO, UX, or digital product optimization.

  • Fluent in GA4, Tag Manager, Hotjar/Clarity, and event tracking.

  • Experienced with A/B testing tools (Google Optimize, VWO, Optimizely, or similar).

  • Comfortable working with frameworks like ICE or PXL.

  • Combine analytical ability with commercial insight.

  • Strong collaborator and communicator across multiple disciplines.

  • Fluent in Dutch and English; experience in e-commerce, D2C, or healthcare is a plus.

What We Offer

  • The opportunity to help build a fast-growing healthtech scale-up from the inside.

  • Plenty of ownership and freedom to bring your ideas and experiments to life.

  • Collaboration with experienced colleagues while making direct impact yourself.

  • A culture of short lines, speed, and continuous improvement.

  • Career opportunities in a growing marketing & digital team.

  • Hybrid working: partly from our new office in central Rotterdam, partly remote.

Hiring Process

We want the application process at Wellis to be fast, transparent, and personal. Here’s what to expect:

  • Application via our website – leave your details and we’ll be in touch shortly.

  • Introductory chat with Tim (Talent Acquisition) – an informal online call to get to know you and answer your questions.

  • Interview with Robert (CMO) – a deep-dive conversation about the role, your experience, and Wellis’ ambitions.

  • Case & presentation – you’ll prepare a case and present it to Robert and 2 MT members. This way, you get to know us better, and we get to know you.

  • Final conversation with the founders – a closing meeting where you’ll hear more about the bigger Wellis story and feel whether this is the right place for you.

We keep the process compact and clear: you’ll always know what to expect and truly get to know our team before making your decision.
