Senior Polymer Chemist

• 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, while assessing hazards and costs

• Lead and interpret analytical workstreams (DSC, TGA, NMR, SEC, rheology, MFI, viscosity, TAN, mechanical testing, weathering/hydrolytic stability) to define the ideal polymer formulation and achieve the desired mechanical and processing properties

• Work closely together with process engineers to translate R&D findings into robust, scalable processes

• Develop compounds based on our polymer technology in close collaboration with external partners to fine-tune the material properties and enable manifold applications

• Develop sustainable plastic products for a wide range of applications, including extrusion, injection moulding and film blowing to prepare semi-finished product prototypes for 3D printing filaments, fibers or packaging

• Identify and validate new applications in line with our go-to-market strategy, especially within the fields of packaging, 3D printing, textiles and composites

• 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

• Develop depolymerisation procedures to lay the groundwork for selective recycling back to the monomers

• Advanced expertise in polymer chemistry, particularly polyester and polyamide, and at least two years' industrial experience. Ideally, you have a PhD in polymer chemistry, chemistry, or a related field. Experience with biodegradable polymers is advantageous.

• You have hands-on experience in polycondensation (batch and continuous) and polymer processing (compounding, extrusion, injection moulding, film blowing, 3D printing and fibre spinning)

• You have deep familiarity with analytical and characterisation methods: DSC, TGA, NMR, SEC, rheology, mechanical testing (tensile testing, impact strength, HDT), TAN and weathering/hydrolytic stability assessments

• You have proven skills in agile project management, CRO/supplier coordination and patent screening and filing

• You are well-versed in regulatory topics such as REACH/CLP, life cycle assessment (LCA) and recycling and end-of-life strategies

• Excellent communication skills in English (written and spoken); German language skills are advantageous

• You bring a hands-on mindset, structure your work efficiently, and collaborate seamlessly across disciplines – even under the dynamics of a fast-paced start-up environment

• Pioneers in Next-Gen-Plastics – help redesign plastics for a truly circular economy.

• Mission & Values – curiosity, transparency and responsibility guide us daily.

• Startup Mentality – flat hierarchies, agile work and regular workshops.

• Fast Growth – steep learning curves, regular growth talks and plenty of room to scale your role with the company.

• Well-being Perks – Hansefit membership and fresh fruit boost your overall health and well-being.

• Team Spirit – interdisciplinary crew that challenges norms, enjoys regular team events and drives real innovation.

• Leipzig Hub – thrive in an emerging tech hotspot.

• Code of Conduct – integrity, fairness and inclusivity are non-negotiable.
