• Strong experience in industrial water treatment, membrane technology, and/or chemical/physical separation processes.
• Demonstrated success managing comparable engineering projects, ideally in production or manufacturing settings.
• Familiarity with process simulation and optimization software.
• Excellent communication skills and confidence working with internal stakeholders and external partners.
