Process Simulation Engineer

About UsIcorium is an advanced separation technology company redefining refrigerant reclamation. Its proprietary separation technology, built on ionic liquid-based extractive distillation, hollow fiber membranes and pressure swing adsorption using porous materials, recovers high-purity refrigerants from complex mixtures that would otherwise be stockpiled, destroyed or released into the atmosphere. This scalable platform helps the industry meet evolving environmental regulations, reduce waste and advance toward a circular refrigerant economy. Founded in 2022 as a University of Kansas spinout, Icorium is headquartered at KU Innovation Park in Lawrence, Kan., and has earned national recognition for its innovation, including National Science Foundation funding and multiple startup awards.  Position OverviewWe are looking for a Process Simulation Engineer with a strong foundation in ASPEN Plus to support our separation process development.
