Your mission
* Develop and scale up the polycondensation processes of our polyester-based planet-proof plastics.
* Develop and refine end-to-end polycondensation processes (batch and continuous), starting from the dosing of monomers and catalysts, the addition of processing aids (rheology modifiers, stabilisers, etc.) and proceeding through several polymerisation stages until the final polymer pellet is produced.
* Perform techno-economic assessments, process simulations, and mass and energy balance calculations in order to identify the ideal polycondensation process.
* You will work together with seasoned polymer chemists, engineers, and a team of technicians that you will train in practical aspects of process engineering.
* Prepare technical reports and patent disclosures and contribute to peer-reviewed publications where appropriate.
* Ensure SHEQ and sustainability standards are met in all laboratory, pilot and production activities, with a focus on HAZOP analysis and process safety.
Your profile
* Degree in Chemical Engineering, Process Engineering or a related field (M.Sc.) with experience in polycondensation processes.
* A minimum of one year's industrial experience in polycondensation process development and upscaling from kg-lab to t-pilot scale.
* A solid understanding of polymer science, particularly polyesters, including their material properties, manufacturing and processing technologies.
* Well-versed in HAZOP analysis, process simulation, techno-economic analysis, and mass and energy balancing.
* 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.
