ABOUT THE JOB

As we expand our capabilities in data science, we’re looking for a (Principal) Data Scientist to take the lead in shaping and scaling this new vertical.
This is a unique opportunity for a pragmatic and business-focused data scientist who thrives in delivering real-world impact rather than research-driven models. You’ll work hands-on with machine learning, advanced analytics, and AI-driven solutions—while also collaborating with clients and stakeholders to align data science initiatives with business goals.
Responsibilities:
-

Build the Data Science vertical: Define and develop the capabilities, processes, and strategies to establish data science as a key service

• Lead end-to-end data science projects – From problem identification to deployment and impact measurement, ensuring models are practical, scalable, and aligned with business needs
• Develop and deploy machine learning models – Expertise in supervised and unsupervised ML techniques (e.g., regression, classification, clustering) and their application in areas like demand forecasting, churn prediction, and pricing optimization
• Act as a trusted advisor, collaborating with clients to understand their challenges and deliver practical, impactful solutions
• Stay hands-on with data engineering & analytics – Work with SQL, Python (pandas, scikit-learn, NumPy), and modern cloud data stacks (Snowflake, BigQuery, Redshift) to prepare and process data for modeling
• Keep up with emerging trends and tools in data science, leveraging them to improve client results and refine internal processes
• Cultivate a collaborative and innovative team culture, mentoring junior team members as the vertical grows

WHO YOU ARE

You’re not just a Data Scientist—you’re a builder, problem-solver, and strategic thinker who knows how to balance technical sophistication with business impact.

Besides that, we are looking for the following:

• 5+ years of hands-on experience in Data Science, with a proven track record of leading and delivering real-world business-focused ML projects
• An entrepreneurial spirit and the ability to work autonomously to build new initiatives
• Pragmatism in delivering solutions that balance technical sophistication with business feasibility
• Proficiency in Python, SQL, and data science libraries; experience with cloud platforms (AWS, GCP, Azure) is a plus
• Experience deploying models in production environments that interact with modern data warehouses and cloud-based ML services
• Excellent communication skills, with the ability to explain complex concepts to diverse audiences
• Our company language is English, but German is a big plus for client interactions
• Optional: Knowledge of data modelling and data engineering concepts to collaborate effectively with technical teams
