JouwWeb is a fully bootstrapped SaaS company based in Eindhoven and has been named in the Deloitte Fast50 for seven consecutive years. Internationally, we operate under the name Webador, serving over 350,000 small business owners. Our ambition is clear: to scale to 1 million customers by 2030. Despite this growth, we consciously remain a lean team of around 50 colleagues, where everyone makes a visible impact.
Build your own data domain within a Fast50 scale-up. Until now, we’ve handled data, dashboards, and analytics ourselves alongside development and interim specialists. However, our challenges are becoming more complex and business-critical. Marketing budgets are growing, experiments are moving fast, and strategic decisions rely increasingly on data. That’s why we are looking for a Senior Data Scientist—someone who can elevate our data domain to the next level, unravel complex patterns, and fuel our strategic direction with advanced models.
In this role, you will be the architect of our data insights on both a strategic and operational level. Operating at the heart of the organization, you’ll serve as a sparring partner for the Management Team, Marketing, Finance, and Development. You will get full autonomy and authority to take ownership of and shape data science at JouwWeb from the ground up.
You will set the direction in this field through:
-
Advanced Modeling & Forecasting: You analyze and model complex customer behavior to understand where our growth comes from and where it is headed. Think of predicting Customer Lifetime Value (CLV), cohort analysis, churn prediction, and advanced funnel optimizations. Your models will have a direct commercial impact.
-
A/B Testing & Experimentation: You will professionalize our testing culture. You’ll help teams formulate statistically sound hypotheses and A/B tests, and evaluate the results to determine what truly works.
-
Data Structure & KPIs: You build the structure that makes all of this possible. You will develop a clear KPI framework, safeguard the quality of our data sources, and ensure reliable dashboards so management always has the right steering information.
We work with a pragmatic data stack and are open to improvements. You will contribute ideas on how to further professionalize our tooling and data processes. We encourage the use of AI whenever it helps set up analysis, data processing, and reporting faster and more efficiently. Currently, we work with:
-
Python for analysis and modeling
-
Tableau and Looker Studio for dashboarding and data visualization
-
SQL for data processing
You combine technical depth with business acumen. You feel comfortable in an autonomous role with a high level of responsibility and direct visibility to the executive team.
-
Master’s level of working and thinking (WO level)
-
5+ years of experience as a Data Analyst or in a similar role
-
Experience in building predictive models (churn, CLV) and a solid foundation in statistics (hypothesis testing, A/B testing)
-
Very strong SQL skills and experience with dashboarding & data visualization
-
Technical foundational knowledge of data warehousing and data engineering
-
Strong analytical skills combined with commercial insight
-
Hands-on, comfortable in a scale-up environment, and experienced in advising management and executive leadership
-
You resonate with our core values
-
A competitive salary between €5,500 and €7,200 (based on knowledge and experience) plus a bonus scheme
-
A personal learning and development budget of 5% of your annual salary
-
A great pension plan with zero employee contribution
-
We work in a hybrid setup, meaning you decide where you work best—at home or in the office. In time, we aim to have one fixed team day per week
-
A professional yet informal work environment with a flat organizational structure and zero unnecessary meetings
-
On top of that, we offer fun perks when company targets are met—think of nice surprises, team outings, and additional bonuses!
With JouwWeb, small business owners can easily build a professional website or web shop they can be proud of. New AI capabilities within our tool have made starting a website truly child's play!
We like to keep things simple, both in our product and in our processes. We work data-driven and love validating hypotheses through experiments. We have very few meetings; our team works in focus and calm on high-impact improvements.
Do you like the sound of a hybrid work environment, and do you see yourself making a real impact as our Data Scientist in no time? Are you available for 32–40 hours per week and eager to get started? Apply today!
