Familiarity with process simulation software (like Aspen HYSYS or CHEMCAD), project management tools, and safety compliance standards is typically expected. Strong analytical thinking, effective communication, and adaptability are valuable soft skills for managing changing project requirements and collaborating with diverse teams. These skills ensure efficient, safe, and cost-effective process improvements that meet contractual obligations and client expectations.

Do contract process engineers make more money?

Contract process engineers often earn higher hourly rates compared to full-time employees due to the temporary nature of their work and specialized skills.

Experience, certifications, and technical expertise can also influence earning potential in this role.

They often work in industries such as chemicals, pharmaceuticals, oil and gas, or manufacturing, providing technical expertise to improve production efficiency, safety, and quality. Their responsibilities may include process design, equipment specification, project management, and ensuring regulatory compliance. Because they work on a contract basis, their assignments may vary in length and scope depending on the needs of the employer.

What is the difference between Contract Process Engineer vs Process Engineer?

Depending on the industry and project scope, daily responsibilities may include conducting process simulations, collaborating with multidisciplinary teams, preparing technical documentation, and ensuring compliance with safety and quality standards.

Job description

Position Overview:
The Treatment & Recovery Process Engineer is responsible for driving two core outcomes: process improvements that strengthen day-to-day operational consistency, and process improvements that ensure sustained Permit Compliance across the LES Treatment & Recovery network. Under the direction of the AVP Process Operations, the Process Engineer applies engineering skills and principles to evaluate process performance, diagnose issues, and recommend and implement changes that improve both operational reliability and regulatory compliance. This is a hands-on, servant-leadership role: the Process Engineer works directly alongside process and plant operators in the field, leading by example and building operator capability to sustain improvements - not simply directing from a distance. The Process Engineer will drive continuous process improvement and establish standard operating excellence throughout the Treatment & Recovery facilities.
Essential Functions:
Process Improvements - Operations
  • Lead and support process design, optimization, and troubleshooting for FOG, industrial separation systems, and related wastewater treatment units to strengthen operational consistency across sites.
  • Collect and analyze operational data (flows, temperatures, pressures, separation efficiency, etc.) to identify and drive process improvement opportunities.
  • 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.
  • Collaborate with engineering, compliance, and EH&S teams to maintain operational integrity and safety.
  • 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.

Hands-On Servant Leadership
  • 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.
  • Deliver excellent customer service at all levels.
  • Communicate with co-workers, management, clients, vendors and others in a courteous and professional manner.
  • Coordinate with other Liquid Environmental Solutions departments.

General
  • Complete all documents and reports as required.
  • Perform all other duties as assigned.

Education and Experience:
  • Bachelor's degree in Engineering
  • Engineering Management Experience (preferred)
  • 3 - 5 years of Industrial Process Engineering
  • Process operations experience desired

Knowledge and Skills:
  • Experience working with other departments and facilities.
  • Microsoft Office Suite of products including Word, Excel, Project
  • Experience with Access, PowerPoint, and Outlook a plus
  • Proven leadership skills
  • Cost and risk management skills
  • Self-starter
  • Time Management skills
  • Excellent communication, interpersonal and negotiating skills
  • Strong analytical skills
  • Professional, courteous demeanor.

Working Environment:
  • Combination of office and field/plant environments.
  • General office conditions
  • Some light lifting and bending
  • Periods of sitting
  • Evening and/or weekend work hours may be required to meet project deadlines.
  • Travel to project site
