Job Description

Your mission

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.

About us

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: P

lastics 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.
