Job Overview

The Process Engineer (SCADA) is responsible for ensuring safe, efficient, and optimized operation of water and wastewater treatment facilities. The role focuses on process monitoring, troubleshooting, optimization, and digital performance tracking to maintain treated water quality, minimize operating costs, and ensure compliance with contractual and statutory requirements.

The incumbent will lead process stabilization, performance monitoring, mass balance analysis, chemical dosing optimization, membrane performance evaluation, and energy conservation initiatives across systems such as ETP, STP, WTP, RO, EDI, ZLD, and Ultra-Pure Water (UPW) facilities. Integration with SCADA/PLC systems for digital monitoring, reporting, and continuous improvement is a key expectation.
