Polymerization Engineer

Your missionDevelop and a 50 kg batch polycondensation process for our innovative, novel polyester based plastic products as an integral part of aevoloop’s polymer R&D teamBuild and refine an end-to-end polycondensation process, starting from the dosing of monomers and catalysts and the addition of processing aids (e.g. rheology modifiers and stabilisers), proceeding through several polymerisation stages, and finishing with the production of the final polymer pelletPerform techno-economic assessments, process simulations, and mass and energy balance calculations in order to identify the ideal polycondensation processDetermine safety-related process and material parameters and derive appropriate countermeasure strategiesDocument your work and make use of modern digital tools for maximum data efficiencyEnsure SHEQ and sustainability standards are met in all laboratory, pilot and production activities, with a focus on HAZOP analysis and process safetyYour profileDegree in Chemical Engineering, Process Engineering, Polymer Chemistry or a related field (M.Sc. or higher) with experience in polycondensation processesA minimum of two years industrial experience in polycondensation process development on a multi kilogram scaleA solid understanding of polymer science, particularly polyesters, including their material properties, manufacturing and processing technologiesWell-versed in HAZOP analysis, process simulation, techno-economic analysis, and mass and energy balancingExcellent communication skills in English (written and spoken); German language skills are advantageousYou bring a hands-on mindset, structure your work efficiently, and collaborate seamlessly across disciplines – even under the dynamics of a fast-paced start-up environmentWhy 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.ContactIf you have any questions about working at aevoloop or our vacancies, contact us by mail at join@aevoloop.com.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
