Data Analyst

Help Wellis turn data into better decisions across the business. Bring data together, create key metrics, build clear dashboards, and deliver pragmatic analyses that move fast in a scale-up environment.

We're looking for a hands-on, proactive Data Analyst to join us. You will be working with data from multiple systems and translating it into insights for Operations, Finance, Marketing and other teams. You'll work in our Google stack (BigQuery, Looker, GA4) and collaborate closely with stakeholders to improve reporting, data quality, and day-to-day decision-making.

Data is becoming a core part of how Wellis operates — and it's growing quickly in both volume and complexity. To help us make better, faster decisions across the business, we're looking for a Data Analyst who can turn data from multiple systems into clear insights that teams can act on. We're looking for someone who combines strong analytical skills with a pragmatic, business-minded approach — and who takes initiative to find answers, improve data quality, and help shape how Wellis uses data at scale.

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.

As a Data Analyst at Wellis, you'll help teams make better, faster decisions by turning data into clear insights. You'll work across multiple systems (e.g., ecommerce, subscriptions, shipping, CRM and advertising platforms) and bring data together in our Google Cloud environment. From there, you'll build analyses and dashboards that improve visibility, sharpen priorities, and support day-to-day business choices — in a fast-moving scale-up where pragmatism matters.

You'll collaborate closely with stakeholders across the business and translate their questions into reliable reporting and actionable recommendations, while helping improve data quality and consistency as we scale.

You'll join our growing data team, working closely with Margit (Lead Data & Analytics) and Data Analyst. In this role, you'll collaborate directly with key stakeholders across the business, including the leadership team — translating questions into clear analyses and actionable insights. As Wellis continues to scale and add more systems and reporting needs, you'll have plenty of room to take ownership, proactively improve how we work with data, and help set standards for dashboards and decision-making.

• Monday: Sync with stakeholders to align on priorities; review weekend data anomalies; update executive dashboard with key metrics.

• Experience building and maintaining dashboards and self-serve reporting (experience with Looker is a plus).

• Confident combining data from multiple systems and sources (e.g., inventory management, subscriptions, orders, shipping, invoicing and financial).

• Able to work with imperfect data and still deliver clear, actionable insights — pragmatic over perfection.

• Proactive and self-starter: you investigate, iterate, and improve without needing constant direction.

• Strong stakeholder management skills and able to translate business questions into analyses people can act on.

• Fluent in English and preferably Dutch; experience in e-commerce is a plus.

• 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 Amir (Talent Acquisition) – an informal online call to get to know you and answer your questions.

• Interview with Margit (Data) – a deep-dive conversation about your experience, how you approach stakeholders, and how you like to work in a fast-moving environment.

• Case – a practical, business-focused data case to understand how you structure your thinking, make assumptions, and translate insights into recommendations (you don't need "perfect" data to do well here).

• Final conversation with relevant stakeholders – a closing meeting to align on expectations, team fit, and the impact you'll make at Wellis.

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.
