Process Engineer vs. Mechanical Engineer: What Are the Differences?

Both process and mechanical engineers are in high demand due to the critical role they play in designing and improving systems. If you’re interested in a career in engineering, it’s important to understand the key differences between these two types of engineers. In this article, we compare and contrast process and mechanical engineering, and we provide information on job outlook and earnings potential.

What is a Process Engineer?

Process Engineers are responsible for designing, developing, testing and managing industrial processes. They work in a variety of industries, such as food and beverage, pharmaceuticals, oil and gas, and manufacturing. Process Engineers optimize existing processes and develop new ones to increase efficiency and productivity. They use computer simulations to model different process scenarios and make recommendations accordingly. Process Engineers also develop safety procedures and protocols to protect workers and the environment. They may also be responsible for training employees on new processes and procedures.

What is a Mechanical Engineer?

Mechanical Engineers design, develop, build and test mechanical and thermal sensors and devices, including tools, engines and machines. They work in a variety of industries, including the automotive, aerospace, chemical, computer, electronics, metallurgical and manufacturing industries. Mechanical Engineers use computer-aided design (CAD) software to create and analyze designs, as well as to simulate and test how a machine is likely to work. They also may be responsible for supervising the manufacturing process to ensure that products are made according to specifications.

Process Engineer vs. Mechanical Engineer

Here are the main differences between a process engineer and a mechanical engineer.

Job Duties

Process engineers use data to determine the best process for manufacturing a product. They study how machines and people interact and design processes that are efficient. Mechanical engineers develop designs, then oversee the creation of those products, ensuring they’re constructed correctly. They often work closely with other engineers and designers during this process.

Process engineers have many different job duties depending on their role and company. In research and development, they may test new processes or software programs. When implementing a new process, they may train employees and communicate changes. Process engineers also monitor systems like production lines and quality control equipment.

Mechanical engineers typically perform similar job duties regardless of their role or employer. They often spend much of their time in an office working on designs and using CAD software. However, they may spend time in a workshop building prototypes and testing models. Mechanical engineers who work in maintenance may travel to sites where they service machinery.

Job Requirements

Process engineers and mechanical engineers typically need a bachelor’s degree in engineering to enter the field. Some employers may prefer candidates with a master’s degree or higher, but it is not always required. Many process engineers and mechanical engineers pursue licensure through the National Council of Examiners for Engineering and Surveying (NCEES). To become licensed, engineers must pass two exams: the Fundamentals of Engineering exam and the Principles and Practice of Engineering exam. After passing these exams, engineers can use the title “professional engineer” (PE).

Work Environment

Mechanical engineers typically work in an office environment, but they may also travel to different locations to evaluate machinery and equipment. They may spend time on construction sites or in factories to ensure that machines are operating correctly.

Process engineers often work in laboratories where they can test chemical processes and refine them for maximum efficiency. These professionals may also work in offices to develop new methods of production.

Skills

Both process engineers and mechanical engineers use problem-solving skills to find ways to improve the efficiency of a company’s manufacturing processes or products. They also both need technical skills, as they often work with complex systems. However, process engineers typically focus on improving existing processes while mechanical engineers design new products or components.

Process engineers use their knowledge of mathematics, physics and engineering principles to analyze data and identify areas where improvements can be made. They then develop plans to implement those changes and track the results to ensure the improvements are effective. Mechanical engineers use computer-aided design (CAD) software to create models of their products or designs. They also test prototypes to ensure they meet performance standards and make modifications as necessary.

Both of these professionals need to have strong communication skills to interact with colleagues, clients and customers. Process engineers may need to present their findings and recommendations to upper management, while mechanical engineers may need to explain their product designs to clients.

Salary

Process engineers earn an average salary of $85,585 per year, while mechanical engineers earn an average salary of $91,492 per year. Both of these average salaries may vary depending on the size of the company at which you work, location of your job and the level of experience you have prior to pursuing either position.
