Polymer Chemist (f/m/d)

Your missionDevelop polymerisation strategies and a structured R&D plan to prepare the polymer formulations for aevoloop’s novel, polyester-based plastics. Target circular 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.Design and optimize synthesis routes and scale-up to the 100+ kilogram range.Check the principal recyclability of the polymers by developing depolymerisation procedures to lay the groundwork for selective recycling back to the monomers.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.Prepare technical reports and contribute for patent applications.Your profileAdvanced expertise in polymer chemistry, particularly polyester and polyamide that you built within a PhD in polymer chemistry, chemistry, or a related field. Industrial experience in this field is advantageous.You have hands-on experience in polycondensation (polyesters, polyamides) or polyurethane chemistry. Experience with biodegradable and/or circular polymers is advantageous.You have deep familiarity with analytical and characterisation methods for polymers: DSC, TGA, NMR, SEC, rheology, mechanical testing (tensile testing, impact strength, HDT), TAN and weathering/hydrolytic stability assessments.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.Why us?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.About UsWe are aevoloop: A fast-scaling deep-tech startup pioneering Next-Gen-Plastics. Contrary to common belief, plastics remain indispensable where no alternative exists, from critical medical devices to protective gear. That’s why we re-engineer polymers from the ground up, merging the advantages of classic plastics — high-performance and versatile — with a new era of sustainability: turning plastic waste into new materials that are fully circular and biodegradable.Our mission is clear: Plastics are vital for a liveable future, so we develop next-generation materials that enable a truly circular economy. As we achieve new milestones and drive innovation, we continuously expand our team and expertise — giving you the chance to grow your career alongside our impact.Our work is guided by five values: Pioneering, Conscientious, Disruptive, Transparent and Contributive. These drive us to unite the rigour of responsible research with playful innovation and to act as a trusted catalyst for sustainable material solutions.You want to find out more?Press release | aevoloop has secured €8.25 millionArticle from MDR (News media) (German) | Plastik neu denken: Aevoloop entwickelt nachhaltige Kunststoffe aus LeipzigVideo on YouTube (German) | Forscher fragen: Die Plastikwende (2024) mit Manuel HäußlerSPRIN-D Podcast (German) | Interview with our Co-Founder Manuel HäußlerGet our latest news on LinkedIn or our News BlogBe part of our journey to close the loop on plastics and drive the circular economy forward!
