Chemical Engineer (f/m/d) @aevoloop

Intro You will develop and scale up innovative processes for upcycling plastic waste into the building blocks of next-generation polyester-based plastics. Work hands-on with gas-liquid and gas-solid processes, lead pilot and lab-scale projects, and collaborate with a cross-functional team to bring sustainable, circular solutions from concept to world-scale production. Tasks 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. Requirements 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.
