• Lead technical investigations, root cause analyses, treatment chemistry evaluations, and corrective actions to improve system performance and reliability.
• Serve as the go-to technical resource for site operations teams that cannot solve locally.
• Optimize biological wastewater treatment, ion exchange, membrane, and oil-water separation systems at operating brownfield facilities.
• Support boiler feed water production and water chemistry programs that are critical to site utilities and steam systems.
• Guide early-phase (Stage 2 and Stage
  3) capital projects on treatment technology selection and development of the design basis.

• Bachelor's degree (minimum) in Chemical, Environmental, Civil, or a related engineering discipline.
• 10+ years of experience in industrial water, wastewater, and/or produced water treatment, water reuse, or process engineering.
• Hands-on troubleshooting experience on operating industrial water or wastewater systems, beyond design and commissioning alone.
• Deep expertise in one or more of the following: biological wastewater treatment, water chemistry (boiler feed or produced water), ion exchange and membrane processes, or oil-water separation and produced water treatment.
• Experience supporting both operating facilities and capital project execution.
• Proven ability to lead multidisciplinary teams and influence technical decisions across organizations.
• Strong analytical, problem-solving, and communication skills.
• Proficiency in Excel and Word, as the team's design practices and tools are largely Excel-based.
