Polymer Teamlead (f/m/d) Permanent employee | Full-time | A s from now | Leipzig Your mission Lead, empower and further develop the interdisciplinary polymerisation team of chemists, engineers, and chemical and engineering technicians that develop the polymer formulation and polycondensation process. This includes liaising with external C(D)MOs and raw material suppliers while ensuring timelines, budgets, and risk management are met. Defi ne and lead the strategy to prepare the production of our novel plastics on a 100+ kt/a world-scale production plant. Identify and work towards suitable intermediate upscale steps at batch and continuous scales. Develop a R&D strategy to determine key parameters for polymer and polymerisation development. Lead the development of polymer formulations and semi-fi nished product prototypes for a variety of processing technologies, including injection moulding, extrusion, fi lm blowing, fi bre spinning and 3D printing. Prepare technical reports and patent applications. Ensure that SHEQ and sustainability standards are upheld across all laboratory, pilot and production activities, including knowledge of REACH/CLP, LCA, recycling and end-of-life strategies. Your profi le Advanced expertise in polymer chemistry or chemical engineering in the fi eld of polymers, with a particular focus on polycondensation and polyester-based materials. Ideally, you have a PhD in this fi eld. 2-5 years of industrial job experience in the fi eld of polycondensation, polymer processing, and polymer analytics. Hands-on experience of melt polycondensation on a kg-lab, t-pilot scale, and kt-commercial scale, including batch and continuous processes. Solid experience of polymer processing, including compounding, extrusion, injection molding and fi lm blowing. Experience with plastic applications such as 3D printing fi laments, fi bres and packaging would be advantageous. In-depth knowledge of analytical and characterisation methods: DSC, TGA, NMR, SEC, rheology, mechanical testing, end-group analysis and polymer ageing. Knowledge of polycondensate rheology and process simulation and experience with design of experiments models and process window determination. Experience with lab-to-pilot and production scale-up (kg → kt) including raw material and energy balancing. Proven skills in agile project management, C(D)MO/supplier coordination and patent screening and fi ling. Well-versed in regulatory topics (REACH/CLP), life cycle assessment (LCA), recycling, and end-of-life strategies. Proven leadership experience with direct personnel responsibility, ideally in a dynamic, interdisciplinary R&D environment. You know how to empower, develop, and motivate technical teams, set clear goals, provide feedback, and foster a collaborative, high-performance culture. A strong track record of managing cross-functional projects and technical teams in industrial R&D settings and the successful scaling of polymerisation processes. Typically fi ve years' industrial, post-academic job experience, with signifi cant time spent in industrial R&D and a demonstrated ability to lead complex projects at the interface of chemistry, engineering and application. Excellent communication skills in English (written and spoken); German language skills are advantageous.
