About the role

You will take on a key role, working not only operationally but also strategically reshaping and embedding the Data Science function at Knuddels.
Leadership & team building: As the team is evolving, you will continue to expand its structure and foster your team members’ development through coaching and feedback.
Data strategy & culture: Together with company leadership, you will define the long-term data strategy. Your goal is to establish a genuine data-driven culture, empower colleagues, and make data understandable and accessible across the company.
Sparring partner & bridge builder: You act as the data-driven conscience but do not rely on numbers blindly. You link quantitative analyses with qualitative feedback from the community (e.g., through close exchange with Community Management) to form a holistic view and enable well-founded decisions.
Hands-on Data Science: You work operationally with our complex data (millions of events per day) to extract valuable insights using data mining, clustering, forecasting, recommendation systems, and classification.
Quality & processes: You ensure the correctness of our data across systems (DWH, analytics) and establish best practices (e.g., code reviews, documentation) for scalable data-science products.
Business impact: You derive concrete actions from your analyses that deliver the greatest value to our community and secure the long-term success of Knuddels.

Education: You have completed a degree in Computer Science, Mathematics, or have an equivalent qualification.
Leadership mindset: You bring initial leadership experience (e.g., as a team lead or mentor) and are eager to shape, motivate, and develop a team.
Communication strength & resilience: You can explain complex issues clearly to non-technical stakeholders and present confidently, even when you must challenge existing opinions with data.
Commercial thinking: You not only recognize patterns but understand their business implications. You prioritize pragmatically and think in terms of product solutions, not just algorithms.
Analytical excellence: You have a fast grasp of problems, a structured way of working, and a passion for analyzing large structured and unstructured datasets.
AI mindset: You see AI (e.g., LLMs, copilots) as an integral part of modern work. You use relevant tools routinely to increase your efficiency and have ideas for how we can leverage AI to benefit our data analyses or product.
Tech stack: You have excellent skills in SQL, Python (including frameworks such as pandas, PyTorch, or TensorFlow), statistical analysis, and databases. You are also experienced in applying machine learning for forecasting, clustering, and categorization.
Bonus: Knowledge of Java and Mixpanel is a plus.
