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 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
• Are curious and willing to learn, with a positive, team-player attitude.
• Can be present 15–20 hours per week, ideally with 1–2 days at our LEGO Campus in Billund.
• Are passionate about digital technology and eager to contribute to real projects.

What’s in it for you?

• Family Care Leave – We offer enhanced paid leave options for those important times.
• Insurances – All colleagues are covered by our life and disability insurance which provides protection and peace of mind.
• Wellbeing – We want our people to feel well and thrive. We offer resources and benefits to nurture physical and mental wellbeing along with opportunities to build community and inspire creativity.
• Colleague Discount – We know you’ll love to build, so from day 1 you will qualify for our generous colleague discount.
• Bonus – We do our best work to succeed together. When goals are reached and if eligible, you’ll be rewarded through our bonus scheme.
• Workplace – When you join the team you’ll be assigned a primary workplace location i.e. one of our Offices, stores or factories. Our hybrid work policy means an average of 3 days per week in the office. The hiring team will discuss the policy and role eligibility with you during the recruitment process.
• Children are our role models. Their curiosity, creativity and imagination inspire everything we do. We strive to create a diverse, dynamic and inclusive culture of play at the LEGO Group, where everyone feels safe, valued and they belong.
