Job description

About the role

To lead and support process engineering, proposal development, project execution and commissioning of industrial water, wastewater treatment and water reuse systems, including physical-chemical, biological, DAF, membrane filtration/RO, oxidation/AOP and sludge handling processes.

Key responsibilities

• Lead process design and optimization of industrial water, wastewater treatment and reuse systems, including physical-chemical, biological, DAF, membrane filtration/RO, oxidation/AOP and sludge handling processes.

• Perform and review mass and hydraulic balances, process calculations, equipment sizing, chemical dosing, aeration/blower requirements, membrane projections and utility requirements; prepare Process Design Basis, Process Description, PFDs, P&ID inputs and control philosophy.

• Develop technically sound and commercially competitive proposals, including process selection, technical write-ups, equipment sizing, operating cost assessment and value-engineering recommendations.

• Prepare design specifications, Bill of Quantity (BQ) and RFQ documents, and conduct technical evaluation and selection of process equipment and components.

• Support Business Development through site surveys, client meetings, technical presentations and proposal clarifications, translating customer operating requirements into practical process solutions.

• Provide process support during detailed design and project implementation, including review of process/piping layouts, vendor documents, operability, maintainability and multidisciplinary interfaces.

• Lead or participate in testing, commissioning, start-up, performance testing and process troubleshooting; prepare or review commissioning procedures, O&M manuals and technical documentation, and provide client training where required.

• Provide technical guidance to junior engineers and work closely with project, procurement, construction and operations teams to deliver projects safely, on schedule and to required performance standards.

About you

• Degree in Chemical Engineering, Environmental Engineering, or a related engineering discipline.

• Preferably 6 years or more of relevant experience in industrial water/wastewater treatment, with strong hands-on exposure to process design, plant commissioning, troubleshooting and/or O&M.

• Good practical knowledge of industrial wastewater treatment, particularly chemical and biological processes, aeration systems, DAF, membrane filtration and RO-based water reclamation.

• Prior experience in food & beverage, brewery, dairy, palm oil/oleochemical/petrochemical, rubber, oil & gas or other high-strength industrial wastewater applications will be an advantage.

• Proficient in process calculations and technical documentation. Experience with membrane design/projection software such as WAVE or equivalent will be an advantage.

• Able to communicate effectively with clients, vendors and multidisciplinary teams; self-motivated, hands-on and willing to support site commissioning or overseas assignments when required.
