The successful candidate will contribute to projects across the full lifecycle, from feasibility studies and process selection through to detailed design, commissioning and operational support. You will work with multidisciplinary teams to develop practical, efficient and compliant treatment processes for municipal, industrial or commercial applications.


Key responsibilities will include preparing process calculations, mass balances, process flow diagrams, equipment specifications, control philosophies and technical reports. You will assess water quality data, identify treatment requirements and recommend suitable technologies such as clarification, filtration, biological treatment, membrane systems, disinfection, sludge treatment and chemical dosing. The role will involve reviewing designs, supporting equipment procurement, responding to technical queries and assisting with commissioning, performance testing and troubleshooting. You may also be required to visit operational sites, liaise with clients and suppliers, and provide technical guidance to project engineers and other stakeholders.
