    Mechanical engineer requirements

    A successful mechanical engineer needs certain education, experience, training and advanced skills:


    Becoming a mechanical engineer typically requires a bachelor’s degree in mechanical engineering or mechanical engineering technology, followed by earning a state engineering license. Master’s and doctorate programs are also available for those who wish to become experts in a particular area of mechanical engineering. Here are the degrees to obtain to become a mechanical engineer:

    Bachelor’s degree

    After high school graduation, the first step in becoming a mechanical engineer is earning a four-year bachelor’s degree in mechanical engineering or mechanical engineering technology. Most aspiring mechanical engineers choose to pursue a bachelor’s program that is sanctioned by the Accreditation Board for Engineering and Technology. Courses include mathematics, engineering, design, and life and physical sciences, focusing less on theory and more on practical applications. Graduates who pass the Fundamentals of Engineering exam at the end of their undergraduate program can seek jobs as entry-level engineers.

    Master’s degree

    Students who want to specialize in a specific area of mechanical engineering — such as automotive technology, robotics or nuclear energy — need to pursue a master’s degree program. The master’s program typically helps aspiring mechanical engineers gain a deeper knowledge of the principles they learned while earning their bachelor’s degree.

    Doctoral degree

    Mechanical engineers who want to pursue careers in teaching or in conducting research will typically pursue a doctoral degree. Mechanical engineering doctoral programs focus on theory and research, with graduates usually becoming either college professors or researchers in a particular industry.


    Practical training is a significant part of becoming a mechanical engineer. Before attempting to obtain a Professional Engineering license, applicants need at least four years of relevant professional experience. Besides giving them the chance to pursue high-level mechanical engineering roles, professional experience trains engineers in important aspects of the job, such as using modern software tools and learning how to deal with setbacks.


    Mechanical engineers need a Professional Engineer certification to access high-level jobs, as well as specific certifications related to the area of engineering in which they wish to work. These are the certification courses for being licensed as a professional engineer and for some possible specializations:

    Professional Engineer

    Mechanical engineers can earn this certification after earning a bachelor’s degree, passing the Fundamentals of Engineering exam, gaining experience and passing the Principles and Practice of Engineering exam. A PE certification allows them to pursue high-level engineering jobs.

    Certification in manufacturing engineer

    Licensed professional engineers can specialize in manufacturing engineering and gain a better insight into designing, building, managing and operating highly complex production systems.

    Certified Systems Engineering Professional

    Earning this certification acts as proof that a mechanical engineer is capable of independently handling various systems engineering tasks. Later in their career, typically after at least 20 years of systems engineering experience, mechanical engineers can further their knowledge by earning an Expert Systems Engineering Professional certification.


    A mechanical engineer needs a variety of hard and soft skills to perform this role successfully, including:

    Mathematical skills

    Mechanical engineers typically have to use advanced calculus, statistics and other math subjects regularly in designing, analyzing and correcting their work.

    Communication skills

    A typical engineering project consists of large teams of specialists, such as architects, computer scientists and fellow engineers. Mechanical engineers must be able to communicate their ideas to everyone involved in the project. At the same time, they need excellent listening skills as their work is based on receiving and analyzing information from other experts involved in the project.

    Teamwork skills

    Mechanical engineers need to be able to communicate with other parties involved in their projects. They also need to successfully collaborate with other professionals to develop technologies and solve issues. Those professionals may be fellow mechanical engineers or in other professions, like architects or computer scientists.

    Problem-solving skills

    Setbacks can be common when undertaking a highly complex project, and they occur anywhere from the design phase to after the project is completed. A mechanical engineer must have the technical and mental skills to understand the issues that arise and find effective solutions.


    Creating and designing various products requires a high degree of creativity in multiple aspects. Mechanical engineers have to be creative enough to invent the product itself and also to create ways in which it’s finished in due time and within the allocated budget.

    Mechanical engineer work environment

    Mechanical engineers typically work in engineering services, research and development, and manufacturing departments. They spend most of their professional time indoors, working in offices. They occasionally visit project sites when an issue that needs on-site analysis occurs. The job typically implies collaborating with different professionals, such as other engineers, engineering technicians, architects, computer scientists and other professionals. Although working as a construction engineer is typically a full-time position with set hours, it is common for construction engineers to work overtime, sometimes more than 50 hours per week.

    How to become a mechanical engineer

    Here are the steps you can take to become a mechanical engineer:

    1. Earn a bachelor’s degree.

    The first step to becoming a mechanical engineer is enrolling in a four-year bachelor’s program after graduating high school.
