What is a chemical process engineer?

A chemical process engineer’s responsibilities cover designing and developing processes for transforming raw materials into marketable products. You can hold a chemical process engineer job in an industry that processes natural gases, paper, pharmaceuticals, plastic, food, and other products. You will analyze procedures, communicate effectively with team members, apply math, science, and engineering concepts, and conduct experiments and report the results. Many types of chemical engineering careers exist in chemical production and manufacturing, mineral processing, oil exploration, sustainable engineering, and alternative energy fields. However, you can find chemical engineers with diverse duties in jobs in nearly every industry that creates a product.

What does a chemical process engineer do?

A Chemical Process Engineer is responsible for designing, developing, and optimizing processes used in the production of chemicals, fuels, pharmaceuticals, food, and other products. They work to improve efficiency, safety, and sustainability in manufacturing plants by analyzing chemical reactions, equipment, and workflows. Chemical Process Engineers often collaborate with other engineers and technicians to troubleshoot problems and implement new technologies in production systems.

What are the key skills and qualifications needed to thrive as a chemical process engineer, and why are they important?

To thrive as a Chemical Process Engineer, you need a solid background in chemical engineering principles, process design, and safety regulations, typically supported by a bachelor's degree in chemical engineering or a related field. Familiarity with process simulation software (such as Aspen Plus or HYSYS), knowledge of P&ID development, and relevant certifications like Six Sigma are highly valuable. Strong analytical thinking, problem-solving skills, and effective teamwork and communication abilities help you excel in this role. These skills ensure that processes are efficient, safe, and cost-effective, supporting both operational excellence and regulatory compliance.

What are some typical challenges a chemical process engineer faces when optimizing plant operations?

Chemical Process Engineers often encounter challenges such as balancing production efficiency with safety and environmental regulations, troubleshooting unexpected equipment malfunctions, and integrating new technologies into existing systems. They must collaborate closely with multidisciplinary teams, including operators, maintenance staff, and quality control, to implement process improvements. Staying adaptable and proactive in problem-solving is key to overcoming these challenges while maintaining smooth and cost-effective operations.

What is the difference between Chemical Process Engineer vs Chemical Production Technician?

AspectChemical Process EngineerChemical Production Technician
CredentialsBachelor's degree in chemical engineering or related fieldAssociate's degree or technical certification in chemical technology
Work EnvironmentDesign, optimize, and oversee chemical processes in labs or plantsOperate and maintain equipment on the production floor
Employer & Industry UsageManufacturing, petrochemical, pharmaceuticals, and energy sectorsChemical manufacturing plants and processing facilities

The Chemical Process Engineer focuses on designing and improving chemical processes, requiring a degree in engineering. In contrast, the Chemical Production Technician handles daily operations and equipment maintenance, often with technical certifications. Both roles are vital in chemical industries but differ in responsibilities, education, and work scope.

Job description

Joining Arup

Arup's purpose, shared values and collaborative approach has set us apart for 80 years, guiding how we shape a better world.

Our process chemical and process engineering team comprises specialist chemical engineers, scientists and industrial experts who shape everything from conceptual design ideas through pre-FEED and FEED to completed turnkey facilities. We support projects at all stages of delivery, ensuring safe, regulatory compliant solutions. We focus on design development, process optimisation, debottlenecking and control of chemical, physical, and biological process, from hydrogen production to carbon capture and transformation through to water and wastewater treatment.

We are looking for candidates with a background in Process engineering design on multi-disciplinary projects within the municipal and industrial water sectors. With our depth and breadth of skills, our team is currently involved in many exciting projects across the Energy, Water and Resources sectors. Whilst the team is based across the UK, much of our work involves supporting projects internationally, integrating with teams in our offices across the globe.
 

The Opportunity

We are looking for candidates with a background in Process engineering design on multi-disciplinary projects within the municipal and industrial water sectors. With our depth and breadth of skills, our team is currently involved in many exciting projects across the Energy, Water and Resources sectors. Whilst the team is based across the North of England, much of our work involves supporting projects internationally, integrating with teams in our offices across the globe.

As a senior engineer you are likely to have ability to work across the project life cycle from developing concept designs to outline and detailed designs, and skills working in or directing process engineering teams to ensure production of deliverables to established timelines and within budget.

What you'll do

You will co-ordinate the work of others and liaise with engineers of other disciplines, imparting your knowledge and experiences. You will be working in highly regulated sectors, within a gated design and project delivery process. You will be involved in the development of mass and energy balances, process data sheets, control philosophies, and commissioning plans. You will also be involved in report writing and the development of fee proposals and feasibility studies of plant operating and capital costs. We would expect you to have a practical comprehension of how your designs will be implemented, and of digital approaches to solve our problems, including the relevant current analysis and design software.

We operate an enviable graduate training scheme, which is accredited by the IChemE, and as a senior engineer you will be expected to join the mentoring programme and help to shape our future pipeline of process engineers. We are looking for candidates with experience of a variety of technologies needed for the treatment of potable water, wastewater and biosolids processing.

The successful candidates are likely to have design experience of the following: fixed and suspended growth systems, anaerobic treatment of biosolids and high-strength effluent, biogas handling and upgrading, membrane separation, solids filtration, disinfection, oxygenation, thermal hydrolysis, nutrient removal processes, chemical storage and dosing systems, along with some experience of HazOp, DSEAR, COMAH, SIL determination, flammable gas handling and compression.
