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.
