Technical Development Chemist - Sustainable Polymers (f/m/d)

Leipzig Vollzeit Kein Home Office möglich

Your mission

Develop polymer formulations and polymerisation strategies for aevoloop’s novel polyester based Planet-Proof 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 10+ 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.
Develop depolymerisation procedures to lay the groundwork for selective recycling back to the monomers.
Prepare technical reports and patent applications, and contribute to peer-reviewed publications where appropriate.
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 profile

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.
Proven skills in agile project management, CRO/supplier coordination and patent screening and filing.
You are well-versed in regulatory topics (REACH/CLP), life cycle assessment (LCA), 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.

About us

We are aevoloop: A fast-scaling deep-tech startup pioneering Planet-Proof 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, robust, cost-effective — 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.
