Polymer Chemist (f/m/d)

Permanent employee, Full-time · Leipzig

Your mission

Join aevoloop, one of Europe’s fast-scaling deep-tech startups, and help build pioneering next-generation plastics.

  • 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.

Your profile
  • 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.

Why us?
  • Real Impact: Help redesign plastics for a truly circular economy.
  • Startup Mindset: Flat hierarchies, fast decisions and early responsibility as we scale.
  • Team Culture: Join a team of curious minds that challenge each other, collaborate openly and celebrate progress together.
  • Growth & Learning: Steep learning curves, regular feedback and room to grow with the company.
  • Well-being Perks – Hansefit membership and fresh fruit boost your overall health and well-being.
