Position Overview

Liquid Environmental Solutions is seeking a hands-on Process Engineer to support field-based process improvement efforts across our Treatment & Recovery (T&R) facilities. This role is ideal for someone who thrives in industrial environments, enjoys working with pumps, tanks, valves, and piping systems, and is comfortable analyzing process data, conducting field audits, and leading plant troubleshooting efforts.

Under the direction of the Director of Process Operations & Efficiency, this engineer will be responsible for optimizing system performance, standardizing operations, and driving measurable improvements in treatment quality and cost efficiency.

If you're motivated by real-world engineering, on-site problem solving, and the opportunity to shape operational excellence across a national network—this is your role.

Key Responsibilities

• Lead and support process design, optimization, and troubleshooting for FOG separation systems and industrial wastewater treatment units
• Conduct field audits to evaluate system performance and identify opportunities for improvement, reliability, or cost savings
• Partner closely with operations teams to ensure consistent application of process standards and regulatory compliance
• Recommend and implement best practices, equipment upgrades, and process changes
• Support commissioning and startup of new or upgraded treatment sites
• Collect and analyze operational data (e.g., flow, temperature, pressure, separation efficiency)
• Ensure P&IDs and all process documentation are accurate and up to date across sites
• Work cross-functionally with engineering, compliance, and EH&S to support safe and stable operations
• Provide technical input on T&R capital projects and scope development
• Develop and present written reports summarizing findings, performance evaluations, and improvement recommendations

Preferred Experience & Technical Focus

While not all are required, the following are strongly preferred:

• Experience with liquid and fluid handling systems: piping, pumps, tanks, separators, mixers, flow control, etc.
• Comfort creating and/or interpreting P&IDs and process flow diagrams
• Familiarity with process audits, valve troubleshooting, and control narratives
• Strong understanding of industrial operations (chemical, petrochemical, refining, or industrial wastewater ideal)
• Previous involvement with commissioning, turnaround support, or startup activities
• Ability to work independently in the field and communicate technical issues clearly with both operators and leadership

Qualifications

• Bachelor's degree in Engineering (Chemical, Mechanical, or related discipline required)
• 35+ years of industrial process engineering experience (not biotech/pharma)
• Engineering management experience a plus
• Proven ability to communicate clearly, work collaboratively, and drive results across departments
• Strong data analysis, documentation, and time management skills
• Proficiency in Microsoft Office; experience with Aspen, DeltaV, or similar tools a plus

Working Conditions

• Office + field-based role, with up to 50% travel required to support treatment facilities
• Must be comfortable in industrial environments and committed to strict safety compliance
• Occasional evening or weekend work may be required to meet project timelines
