• Develop 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.

• Advanced 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.

• 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.

We 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.
