Senior Data Scientist Warehousing – Product team Optimize Stock Steering

Innovate Storage Strategy and Maximize Warehouse Capacity Utilization

How do you make our customers happy?

By developing and optimizing plans and models that increase the storage capacity of our warehouses. On-time delivery of customer orders is a key responsibility of our warehousing teams. Because our warehouse capacity is not unlimited, we must make smart decisions about what articles to store, and where, to guarantee fast delivery to our customers.

As a Senior Data Scientist in the Optimize Stock Steering team, you will play a central role in optimizing existing processes as well as designing new ones that help us get the most out of our warehouses. This is a complex puzzle to solve together with our multidisciplinary team. Ultimately, your involvement and technical skills will directly increase the number of items we can process — which contributes to one of bol’s key organizational goals.

To succeed in this role, experience in working with SQL (BigQuery) and Python is essential. Bonus points if you bring Data Engineering experience (ETL, Airflow), have worked with Google Cloud Platform, or are familiar with Kotlin/Java.

The biggest challenge

Our warehouses are large, but not infinite. The challenge is to find the right balance between capacity, operational efficiency, and the customer promise. This requires more than just building models; it demands strategic thinking about how decisions ripple through the logistics chain. You will need to quickly grasp complex challenges, consider feasibility, and balance innovation with pragmatism: what works today and scales tomorrow.

What you’ll do as Data Scientist

• Develop and deploy data science models that optimize warehouse storage capacity
• Quantify the impact of operational decisions and steering mechanisms
• Translate complex insights into clear and actionable advice for stakeholders

• Collaborate with engineers and logistics process specialists to bring models into daily operations
• Inspire and guide colleagues not only in your team, but also in the broader warehousing domain, with your data science expertise and passion for AI.
• Continuously improve and innovate processes to unlock more capacity in our warehouses

Why you can make difference

You combine technical expertise with strategic thinking and strong communication skills. You thrive on solving complex puzzles in a collaborative setting and are motivated by directly contributing to a key company goal.

3 reasons why this is (not) for you

• - You prefer a role that focuses only on technical modeling without business context
• - You find stakeholder management or cross-functional collaboration challenging
• - You are not motivated by logistics or supply chain optimization problems

• + You have ~7 years of data science experience and are familiar with Operations Research methods
• + You can quickly grasp complex challenges, identify key insights, and translate them to both technical and non-technical audiences
• + You are pragmatic, hands-on, and energized by working in multidisciplinary teams

This is where you’ll work
