Job description

• Basic up to $5,000 + Bonus

• Permanent Role

• Minimum 5 years of experience in industrial wastewater or hazardous wastewater treatment

About the role

The WWTP Process Engineer is responsible for the operation, monitoring, optimization, and continuous improvement of industrial and hazardous wastewater treatment processes at the wastewater treatment plant (WWTP). This role provides technical judgment, process troubleshooting, and engineering support to ensure stable compliance with discharge standards, operational efficiency, and EHS requirements.

Key responsibilities

• Conduct daily operation, monitoring, and optimization of industrial and hazardous wastewater treatment systems including physico-chemical treatment, advanced oxidation processes, biological treatment, and tertiary/polishing treatment units

• Adjust operating parameters based on influent water quality variations (COD, BOD, SS, oil & grease, toxicity, etc.)

• Conduct technical evaluation of new incoming wastewater or waste streams and determine suitable treatment routes and pretreatment requirements

• Plan, organize, and execute bench-scale tests (e.g. jar tests, pilot trials) to verify treatment feasibility

• Provide technical recommendations to support operational decisions and commercial assessments

• Handle system abnormalities such as effluent non-compliance, biological inhibition, membrane fouling, and process instability

• Perform root cause analysis (RCA) and propose corrective and preventive actions (CAPA)

• Prepare, update, and maintain SOPs, process operating parameters, and technical reports

• Guide technicians and laboratory staff on sampling, testing, and on-site process adjustments

• Ensure safe operation of chemical systems, advanced oxidation units, and biological treatment processes in compliance with EHS requirements

Requirement

• Bachelor's degree or above in Environmental Engineering, Chemical Engineering, Applied Chemistry, Biotechnology, or related disciplines

• Minimum 5 years of experience in industrial wastewater or hazardous wastewater treatment

• Hands-on operational experience in one or more of the following systems is preferred: Advanced oxidation processes (Fenton, electrochemical, ozone, UV), Biological treatment systems (anaerobic + aerobic, MBR)

• Ability to independently perform process evaluation, troubleshooting, and operating parameter optimization

• Strong understanding of common wastewater quality parameters and their impact on treatment systems

• Competent in bench-scale test design and data analysis

• Good communication skills with operations, laboratory teams, and management

• Strong sense of responsibility and ability to make sound technical judgments under abnormal conditions

• Able to work in a plant-based, on-site operational environment
