Across the United States, Liquid Environmental Solutions (LES) handles millions of gallons of non-hazardous liquid waste, turning complex waste streams into reusable resources. As our Process Engineer, you will be the primary catalyst for transforming plant performance across our nationwide network of Treatment & Recovery facilities. You will work alongside Plant Managers and Operators to identify root cause of process and compliance issues and implementing effective corrective actions.

In this high-visibility role, your technical expertise directly dictates business outcomes: every process optimization you execute immediately reduces operational bottlenecks, boosts throughput, and drives revenue. By embedding operational consistency into our facilities, you will eliminate compliance risks before they occur - ensuring 100% permit adherence while maximizing facility profitability and plant efficiency.

• Assist with commissioning and start-up activities at new or upgraded treatment sites.
• Support T&R’s Capital Plan, providing process evaluation and expertise to support developing project scope for the T&R facilities.

Process Improvements – Compliance

• Monitor and assess treatment system performance for Permit Compliance; identify and implement process improvements that close compliance gaps, reduce risk, and capture cost savings.
• Ensure process documentation is accurate and updated across sites to support compliance and audit readiness.

• While at operating sites, all activities should be performed in compliance with Company and site safety guidelines and in compliance with local, state and federal regulations at all times.
• Compile and analyze various reports to support decision-making, management reporting, and compliance.
• Partner with, and work directly alongside, local operations teams in the field to build operator capability and ensure consistent adherence to process standards and regulatory requirements.
• Conduct process audits, implement best practices, and recommend equipment or process upgrades - leading hands-on with plant operators rather than directing from a distance.
• Provide summary reports with process evaluation and recommendations to Treatment and Recovery Management and Site Management.

• Coordinate with other Liquid Environmental Solutions departments.
