• Develop and scale up aevoloop’s innovative process for upcycling plastic waste streams into the building blocks for our novel polyester-based plastics, up to a 100+ kt/a world-scale process.

• Build and refine end-to-end gas-liquid / gas-solid processes, starting from the dosing of plastic waste streams, identifying the right reaction conditions, until aevoloop’s key intermediates are formed.

• Design and set up kg-lab scale batch and t-scale pilot continuous processes.

• Perform techno-economic assessments, process simulations, and mass and energy balance calculations in order to identify the ideal upcycling process.

• You will work alongside seasoned chemists and a team of technicians that you will train in the practical aspects of process engineering.

• Prepare technical reports and patent disclosures.

• Ensure SHEQ and sustainability standards are met in all laboratory, pilot and production activities, with a focus on HAZOP analysis and process safety.

• Degree in Chemical Engineering, Process Engineering or a related field (M.Sc.) with experience in gas-liquid processes. Ideally, you have a PhD in this field.

• A minimum of two years’ industrial experience in gas-liquid / gas-solid process development and upscaling from kg-lab to t-pilot scale.

• A solid understanding of polymer science, particularly polyolefins, including their applications, formulation, and behaviour.

• Expertise in gasification and partial oxidation processes is advantageous.

• 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.

• 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.
