What is a processing engineer?

A processing engineer provides development insight and support to technicians. As a processing engineer, you may work alone or in a team to identify problems and solve manufacturing or equipment issues. Processing engineers train staff on equipment use and improve procedures for manufacturing. Qualifications to become a processing engineer include a bachelor’s degree in mechanical engineering or a related field and experience in the manufacturing industry.

What are the key skills and qualifications needed to thrive as a processing engineer?

A Processing Engineer needs a solid background in chemical, mechanical, or process engineering, often requiring a relevant degree and experience in process design or optimization. Familiarity with process simulation software such as Aspen HYSYS or MATLAB, and knowledge of industrial standards and safety certifications like Six Sigma or OSHA are typical. Strong analytical thinking, problem-solving abilities, and effective communication skills help Processing Engineers collaborate with cross-functional teams and troubleshoot complex systems. These competencies are crucial for ensuring efficient, safe, and cost-effective production processes in manufacturing or industrial environments.

What are some common challenges processing engineers face when optimizing manufacturing processes?

Processing Engineers often encounter challenges such as balancing efficiency improvements with maintaining product quality, troubleshooting unexpected production issues, and adapting processes to new materials or technologies. They must work closely with cross-functional teams, including quality assurance and maintenance, to identify bottlenecks and implement solutions. Staying current with industry best practices and continuous improvement methodologies is essential for success in this role.

What is the difference between Processing Engineer vs Manufacturing Engineer?

AspectProcessing EngineerManufacturing Engineer
Primary FocusOptimizing manufacturing processes and equipmentDesigning and improving manufacturing systems and workflows
Work EnvironmentFactories, production lines, process labsFactories, production facilities, plant floor
Common CertificationsSix Sigma, Lean Manufacturing, Process Engineering certificationsSix Sigma, Lean Manufacturing, Manufacturing Technology certifications
Industry UsageElectronics, chemical, semiconductor, automotiveAutomotive, aerospace, consumer goods, industrial equipment

Processing Engineers focus on refining and optimizing manufacturing processes and equipment, ensuring efficiency and quality. Manufacturing Engineers design and improve overall manufacturing systems and workflows to enhance production. While both roles work closely in manufacturing settings, Processing Engineers are more process-specific, whereas Manufacturing Engineers oversee broader system improvements.

Do processing engineers make a lot of money?

Processing engineers typically earn competitive salaries that vary based on experience, location, and industry. In general, they have above-average earning potential compared to many other engineering roles, especially with specialized skills in manufacturing processes, automation, and quality control.

How much does a processing engineer get paid?

Processing engineers typically earn a median annual salary of around $70,000 to $100,000, depending on experience, location, and industry. Salaries can vary based on the complexity of processes managed, certifications held, and the size of the company or facility.

Position Summary
The Project & Process Engineer combines process engineering, continuous improvement, and project execution. The long-term focus of the position will be to identify, develop, and implement opportunities that improve the performance, reliability, efficiency, safety, and economics of our biogas facilities. At the same time, the engineer will be responsible for delivering small modifications, improvement projects, and selected capital projects from concept through commissioning.
This is an ideal position for an engineer who enjoys moving between the plant floor and engineering office, identifying practical problems, developing solutions, and making sure those solutions are successfully implemented.
Key Responsibilities
Continuous Improvement & Process Engineering
  • Identify opportunities to improve plant process performance, energy efficiency, reliability, uptime, operating costs, and environmental performance.
  • Analyze operational data, process performance, equipment behavior, and recurring plant issues to identify improvement opportunities.
  • Develop and evaluate improvement concepts, including technical feasibility, expected benefits, risks, and estimated cost.
  • Lead or support root-cause analysis of process and operational problems.
  • Develop process calculations, mass and energy balances, equipment sizing, process descriptions, and technical specifications as required.
  • Work closely with operations and maintenance teams to identify practical improvements and ensure solutions address the underlying operational need.
  • Establish and track KPIs to demonstrate the impact of implemented improvements.
  • Maintain an improvement pipeline and help prioritize opportunities based on value, risk, and ease of implementation.

Project Development & Execution
  • Lead the execution of small modifications and improvement projects, from initial scope definition through commissioning and closeout.
  • Translate operational needs into clear project scopes, budgets, schedules, and execution plans.
  • Coordinate engineering, procurement, contractors, vendors, operations, and maintenance resources.
  • Develop or manage engineering deliverables including PFDs, P&IDs, equipment specifications, layouts, calculations, and technical documentation.
  • Support equipment and vendor selection and manage technical interfaces with suppliers.
  • Manage project cost, schedule, scope, quality, and safety.
  • Participate in construction, installation, commissioning, startup, and performance verification.
  • Ensure completed projects are properly documented and handed over to operations and maintenance.

Biogas Plant & Technical Support
  • Develop a strong understanding of the company's biogas processes, technologies, equipment, and operating philosophy.
  • Provide technical support to operating facilities and development projects.
  • Troubleshoot process and equipment issues and develop practical corrective actions.
  • Support process safety reviews, management of change, HAZOP/HAZID activities, and other risk-management processes.
  • Identify opportunities for standardization and replication of successful improvements across the company's biogas portfolio.

Required Qualifications
  • Bachelor's degree in Chemical Engineering, Mechanical Engineering, Environmental Engineering, or a related engineering discipline.
  • Approximately 3-8 years of relevant engineering or project experience, preferably in biogas, anaerobic digestion, wastewater, renewable energy, chemical processing, industrial utilities, or a similar process industry.
  • Experience taking projects from concept through implementation and commissioning.
  • Strong process engineering fundamentals, including ability to perform engineering calculations and evaluate process alternatives.
  • Experience working with PFDs, P&IDs, equipment specifications, and engineering documentation.
  • Demonstrated ability to troubleshoot operational problems and develop practical engineering solutions.
  • Experience managing contractors, vendors, and engineering consultants is preferred.
  • Familiarity with process safety, MOC, risk assessment, and industrial safety practices is preferred.
  • Experience with biogas, anaerobic digestion, gas treatment/upgrading, CHP, digestate handling, or related technologies is a strong advantage.

What We Offer
  • Compensation package commensurate with experience including relocation assistance (if applicable), and significant productivity pay and equity.
  • Comprehensive benefits package including health, dental, vision, disability, and life insurance.
  • Paid time off and paid company holidays
  • Opportunity to build upon your career in a company on the cutting edge of the RNG industry.
