Mechanical Engineers

Summary

What Mechanical Engineers Do About this section

Computer technology helps mechanical engineers create and analyze designs.

Mechanical engineers research, design, develop, build, and test mechanical and thermal sensors and devices, including tools, engines, and machines.

Duties

Mechanical engineers typically do the following:

• Analyze problems to see how mechanical and thermal devices might help solve a particular problem
• Design or redesign mechanical and thermal devices or subsystems, using analysis and computer-aided design
• Investigate equipment failures or difficulties to diagnose faulty operation and to recommend remedies
• Develop and test prototypes of devices they design
• Analyze the test results and change the design or system as needed
• Oversee the manufacturing process for the device

Mechanical engineering is one of the broadest engineering fields. Mechanical engineers design and oversee the manufacture of many products ranging from medical devices to new batteries.

Mechanical engineers design power-producing machines, such as electric generators, internal combustion engines, and steam and gas turbines, as well as power-using machines, such as refrigeration and air-conditioning systems.

Mechanical engineers design other machines inside buildings, such as elevators and escalators. They also design material-handling systems, such as conveyor systems and automated transfer stations.

Like other engineers, mechanical engineers use computers extensively. Mechanical engineers are routinely responsible for the integration of sensors, controllers, and machinery. Computer technology helps mechanical engineers create and analyze designs, run simulations and test how a machine is likely to work, interact with connected systems, and generate specifications for parts.

The following are examples of types of mechanical engineers:

Auto research engineers seek to improve the performance of cars. These engineers work to improve traditional features of cars such as suspension, and they also work on aerodynamics and new possible fuels.

Heating and cooling systems engineers work to create and maintain environmental systems wherever temperatures and humidity must be kept within certain limits. They develop such systems for airplanes, trains, cars, schools, and even computer rooms.

Robotic engineers plan, build, and maintain robots. These engineers plan how robots will use sensors for detecting things based on light or smell, and they design how these sensors will fit into the designs of the robots.

Work Environment About this section

Although they do most of their work in an office setting, mechanical engineers also visit worksites to gain firsthand knowledge of their designs.

Mechanical engineers held about 293,100 jobs in 2024. The largest employers of mechanical engineers were as follows:

Mechanical engineers generally work in offices. They may occasionally visit worksites where a problem or piece of equipment needs their personal attention. In most settings, they work with other engineers, engineering technicians, and other professionals as part of a team.

Work Schedules

Most mechanical engineers work full time and some work more than 40 hours a week.

How to Become a Mechanical Engineer About this section

Mechanical engineers analyze problems to see how a mechanical device might help to solve them.

Mechanical engineers typically need a bachelor’s degree in mechanical engineering or mechanical engineering technology. Mechanical engineers who sell services publicly must be licensed in all states and the District of Columbia.

Education

Mechanical engineers typically need a bachelor's degree in mechanical engineering or mechanical engineering technologies. Mechanical engineering programs usually include courses in mathematics and life and physical sciences, as well as engineering and design. Mechanical engineering technology programs focus less on theory and more on the practical application of engineering principles. They may emphasize internships and co-ops to prepare students for work in industry.

Some colleges and universities offer 5-year programs that allow students to obtain both a bachelor’s and a master’s degree. Some 5-year or even 6-year cooperative plans combine classroom study with practical work, enabling students to gain valuable experience and earn money to finance part of their education.

Most employers prefer to hire students from an accredited program. A degree from an accredited program is usually necessary to become a licensed professional engineer.

Licenses, Certifications, and Registrations

Licensure is not required for entry-level positions as a mechanical engineer. A Professional Engineering (PE) license, which allows for higher levels of leadership and independence, can be acquired later in one’s career. Licensed engineers are called professional engineers (PEs). A PE can oversee the work of other engineers, sign off on projects, and provide services directly to the public. State licensure generally requires

• A degree from an accredited engineering program
• A passing score on the Fundamentals of Engineering (FE) exam
• Relevant work experience typically at least 4 years
• A passing score on the Professional Engineering (PE) exam.

The initial FE exam can be taken after one earns a bachelor’s degree. Engineers who pass this exam are commonly called engineers in training (EITs) or engineer interns (EIs). After meeting work experience requirements, EITs and EIs can take the second exam, called the Principles and Practice of Engineering.

Several states require engineers to take continuing education to renew their licenses every year. Most states recognize licensure from other states, as long as the other state’s licensing requirements meet or exceed their own licensing requirements. Information on state licensing board requirements is available from CareerOneStop.

Several professional organizations offer a variety of certification programs for engineers to demonstrate competency in specific fields of mechanical engineering. Information on certifications is available from CareerOneStop.

Important Qualities

The following are examples of qualities that are important for these workers to perform their duties. For more information, visit the Employment Projections (EP) skills data page.

Creativity. Mechanical engineers design and build complex pieces of equipment and machinery. A creative mind is essential for this kind of work.

Listening skills. Mechanical engineers often work on projects with others, such as architects and computer scientists. They must listen to and analyze different approaches made by other experts to complete the task at hand.

Math skills. Mechanical engineers use the principles of calculus, statistics, and other advanced subjects in math for analysis, design, and troubleshooting in their work.

Mechanical skills. Mechanical skills allow engineers to apply basic engineering concepts and mechanical processes to the design of new devices and systems.

Problem-solving skills. Mechanical engineers need good problem-solving skills to take scientific principles and discoveries and use them to design and build useful products.

Advancement

A Ph.D. is essential for engineering faculty positions in higher education, as well as for some research and development programs. Mechanical engineers may earn graduate degrees in engineering or business administration to learn new technology, broaden their education, and enhance their project management skills. Mechanical engineers may become administrators or managers after gaining work experience.
