You'll work with advanced polymer technologies, collaborate with global cross‑functional teams, and have the opportunity to influence product strategy, innovation, and future technology platforms. If you're passionate about solving complex engineering challenges and seeing your ideas become commercial reality, we'd love to hear from you.

For this role, compensation starts from 55.700,00 EUR gross, depending on experience and skills. It sits within a broader package that reflects the overall value of the role.

Your Main Tasks

• Lead the development of new heat‑shrink tubing and sealing products from concept, design, and validation through to industrialisation and product launch.
• Translate customer application requirements into robust product specifications covering thermal, mechanical, electrical, sealing, and environmental performance.
• Develop and optimise polymer‑based solutions including single‑wall and dual‑wall tubing, adhesive‑lined products, sealing sleeves, and moulded components.
• Design, execute, and analyse laboratory, pilot‑scale, and manufacturing trials involving extrusion, crosslinking, expansion, moulding, and adhesive technologies.
• Drive product verification, qualification, risk assessment, and reliability activities using DFMEA, DOE, statistical analysis, and structured problem‑solving tools.
• Investigate technical and manufacturing issues, identify root causes, and implement effective corrective actions to improve product performance and quality.
• Collaborate closely with Product Management, Manufacturing, Quality, Supply Chain, suppliers, and customers to ensure successful product delivery and launch readiness.

Your Ideal Background

• Degree in Polymer Engineering, Materials Science, Chemical Engineering, Mechanical Engineering, Chemistry, or a related technical discipline.
• 5+ years of product development experience, taking complex polymer‑based products from concept through qualification and commercial launch.
• Hands‑on expertise in polymer extrusion and at least one related technology such as heat‑shrink expansion, crosslinking, adhesive lining, moulding, or compounding.
• Strong knowledge of polymers, adhesives, sealants, additives, material characterization, and material‑process‑property relationships.
• Experience with product validation, qualification testing, process scale‑up, manufacturing transfer, and continuous process improvement.
• Practical knowledge of DFMEA, Design of Experiments (DOE), statistical analysis, root cause investigation, risk management, and engineering change control.
• Strong communication, collaboration, and technical leadership skills, with the ability to work effectively across R&D, Manufacturing, Quality, Supply Chain, suppliers, and customers.
