What is a Process Engineer?

Process Engineers design, implement and optimise chemical and biochemical processes, especially continuous flow ones on an industrial scale to turn raw materials such as oil, natural gas or milk (using heat, pressure or a chemical agent) into an end product (e.g. drugs, milk formula, gasoline, beer, butter, bulk chemicals, etc.). Process engineers are typically trained in chemical engineering.

In summary, think of it as making products that have to be mixed or cooked from a formula or recipe but on a huge scale.

According to the BLS, the median annual wage for chemical/process engineers was $106,260 in May 2022 with projected job growth of 9% from 2020 to 2030.

Median level salaries after 5 years of experience range from €70,000 – €80,000 plus overtime, bonuses and allowances. (Irish Salary Calculator)

Process Engineer Vs. Production or Manufacturing Engineer

Process engineers work in the manufacturing industry with the result that their roles are mixed up, confused or conflated with that of a production or manufacturing engineer, i.e. most employment websites, some company job descriptions, (currently) ChatGPT, etc.

Let’s take a look a the difference from the perspective of an engineer standing on the factory floor.

Process Engineers work in Process or Continuous Flow Manufacturing – takes a formulation or recipe of ingredients and using processes such as a chemical or biochemical reaction, heat, cold, mixing, fluidization, crushing, pulverization, screening, sieving, centrifugation, fermentation, distillation, separation, crystallization, evaporation, gas absorption, filtration, diafiltration, polymerization, isomerization, homogenization, pasteurization etc continuously or in a batch to make a final product which is usually a liquid, powder, gas or solid. (Think turning milk into baby formula, oil refining, gasoline, plastic, shampoo, washing powder, toothpaste, casein, cheese, butter, beer, wine, whiskey, paint, drug or vaccine manufacturing, etc)

In a process manufacturing factory, you typically find pipes, tanks, pumps, flow valves, steam valves, temperature gauges, boilers, vessels, reactor vessels, crackers, distillation columns, heat exchangers, boilers, steam pipes, autoclaves, clarifiers, decanters, fluidised dryers, Program Logic Controllers (PLCs) PID (Proportional Integral Derivative) Controllers, etc,

Production and Manufacturing Engineers work in Discrete Manufacturing. This involves (non-chemical or non-biochemical) processes such as machining, assembling,  bolting, screwing, welding, riveting, glueing, forging, extruding, moulding, stamping and machine pressing, things that can be counted and itemised into a distinct product often on an assembly line. (Think car assembly – Toyota or Ford’s production line for electric cars, engines, cell phones, computers, washing machines, ball bearings, screws, wire, copper pipes, TVs, airplanes, syringes, medical pumps, scalpels or pacemakers, etc)

In a discrete manufacturing factory, you typically find, assembly lines, conveyor belts, U-shaped assembly areas, welding stations, machine tools, CNC machine centers, CNC lathes, stamping presses and dies, robots, pick and place (SCARA) robots, injection moulding machines, packing machines, air-powered assembly tools, painting and finishing areas, etc.

In summary, if what you are making needs chemistry like making washing powder, it’s process or chemical engineering, if it involves, cutting metal and welding or bolting something together like a washing machine, it’s manufacturing engineering.

Where Does a Process Engineer Work?

Process engineers spend most of their time in an office or based onsite at industrial plants and other large-scale manufacturing locations. Depending on the role, they are often required to monitor or direct operations or be involved in the design or upgrading of existing facilities. They typically work in the following sectors.

  • Food and dairy
  • Beer and whiskey manufacturing
  • Chemical manufacturing
  • Petrochemical manufacturing
  • Agriculture processing
  • Mineral processing
  • Cosmetics
  • Pharmaceutical and biopharmaceutical manufacturing 
  • Engineering consultancies focused on the above sectors
  • Engineering contractors focused on the above sectors

What Does a Process Engineer Do?

A Process Engineer’s job can be extremely varied.

In larger companies, Process Engineers may specialize in a niche area but in smaller facilities, they can be responsible for a huge variety of tasks.

These tasks can include:

  • Design and development of a continuous manufacturing process along with the layout and equipment for a new factory. This includes creating and setting specifications, developing, implementing and monitoring this equipment as part of the manufacturing system.
  • Commissioning and qualification of that new factory
  • Modify and optimize equipment and processes that are already in place
  • Use of simulation software in the development of new processes
  • Completion of documentation to show and ensure compliance with both internal and external regulations and protocols
  • Oversight of processes and working to maintain optimization of the continuous manufacturing process
  • Monitoring of equipment – including regular testing and ensuring maintenance tasks are carried out
  • Assisting Process Technicians in troubleshooting in the event of a problem
  • Data collection, interpretation and report writing
  • Planning and installation of new equipment
  • Risk assessments of the equipment and processes being used. Of course, this refers to staff safety and safety within the plant, but this can also extend outwards to include things such as the environmental impact
  • Continual evaluation of equipment and processes to ensure both efficiency and quality remain high
  • Budget responsibilities

Process Engineer Vs. Chemical Engineer

For some people, process engineers and chemical engineers are synonymous.

For others, a process engineer is a job title for someone who works in a factory to manage, analyse, optimise chemical and biochemical manufacturing processes, and conduct and manage any maintenance projects. In contrast, chemical engineering is used as a university degree title. However, a chemical engineer can also be used as a job title in the bulk chemical manufacturing or petrochemical manufacturing industry or in roles where there is a huge emphasis on process design.

But as always, there are exceptions.

What Skills Do I Need?

The ideal skill set for someone moving into process engineering includes:

  • Interpret technical drawings – especially process flow diagrams, piping and instrumentation diagrams (P&IDs) and pipe skids
  • Project management – have to ability to manage people, budgets and complex projects and bring them to completion on time and on budget
  • Spatial reasoning – the ability to see a two or three-dimensional object and then mentally manipulate it
  • Critical/logical thinking – have to locate problems, and then think of those problems from a variety of perspectives to assess the best solution
  • Excellent communication skills – working with people across the manufacturing process, they have to be able to manage people well and communicate new ideas effectively
  • Calm under pressure – must be able to troubleshoot at an advanced level. If a problem is delaying manufacturing, they must be able to come up with effective working solutions quickly
  • Commercial awareness – usually working within strict time and budgetary constraints
  • Excellent computer skills – IT is an essential part of this role, uses include simulation software, design software and reporting
  • Analytical skills – responsible for analysis and interpretation of data into charts, diagrams, and reports
  • Negotiation skills – vital if charged with budgetary or schedule management
  • Creative thinking and excellent problem-solving skills – have to be able to solve problems in a new way, seeing past what is established and create a new way of doing things

How Much Money Do Process Engineers Make? What is the Job Growth?

Check out our salary guide for Process Engineers for information local to you.

According to the Bureau of Labor Statistics, chemical engineer (its data includes that of process engineers) jobs will experience significant growth in the near future. For example, the BLS projects an 8% increase in demand for these engineering jobs between 2022 and 2030. Process engineers should experience similar growth.

In Ireland, CPL recruitment lists Process Engineers as an “In Demand” job for 2024.

How Do You Become a Process Engineer?

Typically, a BSc / BEng or Msc / MEng in chemical or process engineering is required.

Typical coursework focuses on:

  • mathematics
  • thermodynamics and fluid mechanics
  • plant design and commissioning
  • phase equilibrium and mass transfer
  • biochemical engineering
  • industrial chemistry
  • organic chemistry
  • environmental engineering
  • cell biology
  • reactor design
  • data analysis for process and product development
  • chemical reaction engineering
  • process dynamics and control
  • chemical process equipment
  • unit operations and particle technology

A BEng in mechanical engineering or a Bachelor of Science (BSc) degree in a related field (such as chemistry) may potentially provide an alternative route into these positions.

If you intend to pursue a more research focused or academic career, a Masters Degree could be advantageous. However, the general consensus is that the majority of career paths do not require Masters Degrees.

Process Engineer Jobs in Pharma and Med Device Manufacturing

As a process or chemical engineer, you are already well-positioned to apply for process or chemical engineering roles within the pharmaceutical manufacturing sector.

You could also look at roles with medical device manufacturing companies as well. Engineering consultancies could also be another option.

You generally don’t need any additional training but you could certainly benefit from taking a course on Good Manufacturing Practices (GMPs) and risk management techniques if you have no experience working in a GMP manufacturing environment or have not covered them in your undergraduate program.

Or you could bolster your qualifications in both pharmaceutical companies and engineering consultancies by taking our program on how to populate an IQ OQ PQ Validation Protocol.  Validation Protocols form a crucial part of pharmaceutical plant projects and having a fundamental understanding of how these protocols are put together and interpreted is a fundamental skillset of any process or chemical engineer working in this area. 

A second option would be to take our Conversion Course into Engineering Roles in Pharma to learn GMPs and the air, water and steam systems that underpin aseptic/sterile processing. Pharma needs purified water and clean air systems to manufacture safe medicines that are used for injections. These aseptic processes have to be designed, validated, monitored, maintained, and updated in FDA-regulated manufacturing facilities.

Process Engineer Resume Tips

As with all resumes, it’s extremely important that you tailor your Process Engineer resume to reflect the language used within the job advert. Where you have relevant experience or skills, use the words and phrases that the employer has used to describe them. Do not assume that someone will read similar wording and know what you mean.

Process Engineer roles will typically be looking for the skills previously outlined:

  • Excellent communication skills
  • Calm under pressure
  • Commercial awareness
  • Critical/logical thinking
  • Excellent computer skills
  • Analytical skills
  • Negotiation skills
  • Creative thinking and excellent problem-solving skills
