Job description

Job Description Would you like to help our team succeed in creating a robust and repeatable solvent welding process for ABS? Bring your curiosity for polymers, solvents and laboratory experimentation to help identify, test and optimize safe, repeatable and high-quality solvent welding solutions for ABS at the LEGO Group.

Applications are reviewed on an ongoing basis. However, please note we do amend or withdraw our jobs and reserve the right to do so at any time, including prior to any advertised closing date.

Core Responsibilities

• Help us research and screen candidate solvents and solvent blends for welding ABS, considering polymer interaction, evaporation rate and practical handling.
• Assist in planning and executing structured laboratory experiments to evaluate key solvent welding variables using Design of Experiments (DoE) principles where appropriate.
• Correlate bond performance with solvent choice and process conditions to help define a practical and repeatable process window.
• Link in with Product Safety (PS) and Environment, Health and Safety (EHS) departments.
• Document test methods, experimental results, conclusions and recommendations in a clear and structured way.
• Document and communicate theoretical chemical background behind empirical observations.

You will join R&D Processing in our brand-new engineering campus in Billund and contribute to a development project focused on solvent welding assembly of ABS parts. Working with experienced colleagues across Materials, Quality, Element Development, Product Safety and EHS.

Do you have what it takes?

• Currently studying Polymer Science, Materials Science, Materials Engineering, Chemistry, Chemical Engineering or a closely related field.
• Enrolled in a relevant bachelor or master programme with an interest in applying academic knowledge through laboratory-based development work.
• Basic understanding of polymer-solvent interactions and an interest in polymers, materials or joining processes.
• Hands‑on interest in planning and carrying out laboratory experiments.
• Ability to analyse data and draw clear, evidence‑based conclusions.
• Strong documentation skills and the ability to communicate methods, results and recommendations clearly.
• Structured, curious and able to work both independently and collaboratively.

Nice to have

• Awareness of laboratory safety, chemical handling and EHS considerations.
• Experience with microscopy, cross‑section preparation or other materials characterization methods.
• Familiarity with mechanical testing methods for bonded or welded joints.
• Experience with Design of Experiments (DoE) or statistical analysis, including advanced or dynamic DoE approaches.
• Specific knowledge of ABS and solvent‑based polymer joining.

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.
