Do you want to play a key role in turning plastic waste into valuable chemical building blocks for new, sustainable plastics? At aevoloop, you will take ownership of developing, optimizing, and scaling innovative upcycling processes—from lab to production. You will lead an interdisciplinary team and help shape the future of the circular economy.

• Technology Development: Plastics to chemical intermediates. 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. This includes liaising with external C(D)MOs and raw material suppliers while ensuring timelines, budgets, and risk management are met.
• End-to-End ownership of the process. Play an active role in building a reactor according to the design you draft with your team. Collect all data, process them and draw the respective conclusion. You will directly report to the management team and will discuss the results with them.
• Define and lead the strategy to scale up aevoloop’s innovative process for upcycling plastic waste streams into the building blocks for our novel polyester-based plastics. Reach a 50 kg/day batch process.
• Perform techno-economic assessments, process simulations, and mass and energy balance calculations in order to identify the ideal upcycling process.
• Lead, empower and further develop the interdisciplinary plastic waste upcycling team of chemists, and chemical and engineering technicians.
• 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.
• 2-5 years of industrial job experience in chemical process development on different scales larger than lab scale. A minimum of two years’ industrial experience in gas-liquid / gas-solid process development and upscaling from kg-lab to t-pilot scale. Expertise in gasification and partial oxidation processes is advantageous.
• A solid understanding of polymer science, particularly polyolefins.
• Proven skills in agile project management and C(D)MO/supplier coordination.
• Proven leadership experience with direct personnel responsibility, ideally in a dynamic, interdisciplinary R&D environment. You know how to empower, develop, and motivate technical teams, set clear goals, provide feedback, and foster a collaborative, high-performance culture.
• 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.
