Leipzig, DE · Full-time · €55,000 – €80,000

About this role

Develop polymer formulations and polymerisation strategies for aevoloop’s novel, polyester-based plastics. Define the desired properties of the target polymer and develop a R&D plan to achieve them. Design and optimize synthesis routes and scale-up to the 100+ kilogram range, assessing hazards and costs.

Lead and interpret analytical workstreams including DSC, TGA, NMR, SEC, rheology, MFI, viscosity, TAN, mechanical testing, and weathering/hydrolytic stability. Define the ideal polymer formulation to achieve desired mechanical and processing properties. Work closely with process engineers to translate R&D findings into robust, scalable processes.

Develop compounds based on polymer technology in collaboration with external partners to fine-tune material properties. Create sustainable plastic products for extrusion, injection moulding, and film blowing, preparing prototypes for 3D printing filaments, fibers, or packaging. Identify and validate new applications in packaging, 3D printing, textiles, and composites.

Join pioneers in next-gen plastics to redesign for a circular economy, guided by curiosity, transparency, and responsibility. Thrive in a startup with flat hierarchies, agile work, steep learning curves, and growth talks. Enjoy team spirit, regular events, Hansefit membership, fresh fruit, and Leipzig's tech hub.

Requirements

Advanced expertise in polymer chemistry, particularly polyester and polyamide, with at least two years' industrial experience
Hands-on experience in polycondensation (batch and continuous) and polymer processing (compounding, extrusion, injection moulding, film blowing, 3D printing, fibre spinning)
Deep familiarity with analytical methods: DSC, TGA, NMR, SEC, rheology, mechanical testing, TAN, weathering/hydrolytic stability
Proven skills in agile project management, CRO/supplier coordination, and patent screening/filing
Well-versed in REACH/CLP, life cycle assessment (LCA), recycling, and end-of-life strategies
Excellent communication skills in English (written and spoken); German advantageous
Hands-on mindset, efficient work structure, seamless cross-disciplinary collaboration in fast-paced startup
