You will develop and scale up polycondensation processes for innovative polyester-based plastics – from lab scale to world-scale production. Collaborate with an interdisciplinary team, help shape next-generation materials for a truly circular economy, and leverage your expertise in a fast-growing deep-tech startup.

## Tasks

*   Develop and scale up polycondensation processes for our novel polyester-based plastics to enable production at a world-scale plant of over 100 kt/a.
*   Build and refine end-to-end polycondensation processes (kg-scale batch and tonne-scale continuous), starting from the dosing of monomers and catalysts and the addition of processing aids (e.g. rheology modifiers and stabilisers), proceeding through several polymerisation stages, and finishing with the production of the final polymer pellet.
*   Identify bottlenecks and technical challenges through lab-scale screening experiments. Overcome these and implement fixes to optimise the polycondensation procedure.
*   Perform techno-economic assessments, process simulations, and mass and energy balance calculations in order to identify the ideal polycondensation process.
*   You will work alongside seasoned polymer chemists and engineers, as well as training a team of technicians in the 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.

## Requirements

*   Degree in Chemical Engineering, Process Engineering or a related field (M.Sc. or higher) with experience in polycondensation processes.
*   A minimum of two years industrial experience in polycondensation process development and upscaling from kg-lab to t-pilot scale to kt-commercial 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.

## Benefits

*   **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.
*   **Fast Growth** – steep learning curves, regular growth talks and plenty of room to scale your role with the company.
*   **Well-being Perks** – Hansefit membership and fresh fruit boost your overall health and well-being.
*   **Team Spirit** – interdisciplinary crew that challenges norms, enjoys regular team events and drives real innovation.
*   **Leipzig Hub** – thrive in an emerging tech hotspot.
*   **Code of Conduct** – integrity, fairness and inclusivity are non-negotiable.

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.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.
