Job Description
Just imagine helping decide which LEGO® sets appear on shelves for different customers around the world. Then make it real.
About the role
As our Data Science Student Worker, you'll support the team behind the next version of our stock keeping unit (SKU) performance scoring system, run experiments to improve novelty predictions, and help evolve assortment optimization tools. You'll work alongside experienced data scientists on real production pipelines, contributing to data preparation, experimentation, analysis, and production code. It's a hands-on role designed to help you learn while making a meaningful contribution from week one.
Required Qualifications
Solid Python fundamentals
Good understanding of data analysis and machine learning concepts, e.g. from coursework or other experience
Comfortable with SQL and working with tabular data
Fluent English
Preferred Qualifications
Exposure to optimization / operations research (e.g. linear programming)
Familiarity with cloud data platforms (Databricks, AWS)
Experience with pyspark
What you'll build
Support the development of the next generation of SKU performance scoring capabilities
Run experiments that improve prediction models and generate actionable insights
Contribute to assortment optimisation tools used by hundreds of users every day
Help maintain and improve production data science solutions
Work with experienced team members to turn analysis into practical outcomes
If you've worked in a role where you used real data to answer business questions, you'll feel at home here. What matters most is your ability to learn, contribute to shared code, and translate analysis into meaningful improvements.
Life on the team
You'll join the Assortment & Space Management team within Digital Technology. We help deliver customer- and channel-specific assortment recommendations while creating greater portfolio transparency across the business. Our team works in a hybrid rhythm with daily stand-ups and weekly team sessions, including anchor days on Tuesdays and Thursdays. You'll work closely with data scientists and software engineers while bringing curiosity, reliability, and a strong team spirit to everything you do.
What success looks like
Success means confidently contributing to production systems, running experiments that improve model performance, and becoming a trusted member of the team. Over the next 12 to 18 months, we're focused on rolling out a new version of our core product performance scoring and prediction system. You'll work closely with data scientists and software engineers to help shape that journey while building skills that can grow with you at the LEGO Group.
We're looking for students who
Are currently enrolled in Denmark in a Bachelor’s, Master’s, or Erhvervsakademi (professional academy) program in fields related to data.
Preferably graduating summer 2028 or beyond, having at least 1.5-2 years left of studies
