What Is Required to Be a Mechanical Engineer?
To become a mechanical engineer, you'll likely need a bachelor's degree in mechanical engineering or mechanical engineering technology. You may also qualify for certain positions with a degree in a related engineering discipline, depending on the employer and your technical background.
According to the U.S. Bureau of Labor Statistics (BLS), undergraduate mechanical engineering programs generally combine coursework in mathematics, physical sciences, engineering principles and design.1 These subjects help you understand how mechanical systems behave and develop solutions that meet performance, safety and efficiency requirements.
Core areas of study commonly include:
- Thermodynamics: The relationships among heat, energy and work, and their applications in engines, power systems and other technologies
- Fluid mechanics: The behavior of liquids and gases, including their movement through mechanical systems
- Mechanics and structural analysis: The effects of forces, motion and stress on materials, components and structures
- Materials science: The properties of engineering materials and how they influence design, durability and performance
- Mathematics and computational methods: Analytical techniques used to model, evaluate and solve engineering problems
Professional Engineering Licensure
You generally don't need a Professional Engineer (PE) license to begin working as a mechanical engineer. However, you may need one if you want to provide engineering services directly to the public, approve certain engineering plans or assume responsibilities that require a licensed engineer.
Although requirements vary by state, the usual path to PE licensure includes completing an accredited engineering degree, passing the Fundamentals of Engineering (FE) examination, gaining qualifying professional experience and passing the Principles and Practice of Engineering (PE) examination.1
Licensure and graduate education serve different purposes. A PE license establishes qualifications for specific professional responsibilities, while a master's degree provides opportunities to develop additional technical and analytical expertise.
Steps to Become a Mechanical Engineer
1. Build a Strong Foundation in Mathematics and Science
Preparation for mechanical engineering often begins with coursework in mathematics, physics and related sciences. Algebra, geometry, trigonometry and calculus help you develop the quantitative reasoning needed for more advanced engineering subjects.
Robotics activities, engineering clubs and hands-on design projects also give you opportunities to investigate how machines and mechanical systems work.
2. Earn a Bachelor's Degree in Engineering
A bachelor's degree provides the core technical education required for most mechanical engineering positions. Many programs include collaborative design projects and laboratory assignments that give you opportunities to apply engineering principles, evaluate alternatives and communicate your findings.
Accreditation is an important consideration when selecting an undergraduate program. It indicates that a program has met established standards for educational quality and adequately prepares students to enter the engineering profession. Employers often prefer graduates of accredited programs, and graduation from an accredited engineering program is generally part of the requirements for PE licensure.1
3. Gain Practical Engineering Experience
Internships, cooperative education programs and research or laboratory opportunities allow you to see how engineering concepts translate into professional practice. These experiences may involve supporting design teams, analyzing test results, preparing technical documentation or assisting with product development. You'll also gain exposure to the collaborative nature of engineering work, in which projects often require contributions from professionals in several disciplines.
Practical experience helps you build your resume, identify areas of professional interest and develop skills that extend beyond classroom assignments.
4. Begin Your Professional Engineering Career
After completing your undergraduate education, you can pursue entry-level mechanical engineering positions in industries such as manufacturing, transportation, aerospace, energy and research and development.
Early-career responsibilities may include preparing designs, conducting calculations, evaluating materials, testing components and supporting manufacturing processes. As you gain experience and demonstrate your technical judgment, you'll generally take on more complex assignments.
5. Develop Advanced Expertise and Professional Responsibilities
A mechanical engineering career doesn't follow a single path after the first job. You might concentrate on particular technologies or industries, or pursue broader technical responsibilities, research opportunities or engineering leadership. You can also pursue professional certifications to demonstrate specialized technical knowledge. As your career develops, you may need to understand systems beyond your original areas of expertise, evaluate increasingly complex technical problems or coordinate work across engineering disciplines.
Graduate study offers one way to build those capabilities. An advanced degree program can provide deeper knowledge of engineering analysis and design while introducing additional methods and applications relevant to professional practice.
How Many Years to Become a Mechanical Engineer?
For most students, the educational path to an entry-level mechanical engineering position takes approximately four years: the typical length of a full-time bachelor's degree program.
Your timeline may vary depending on your academic preparation, enrollment schedule and participation in cooperative education or combined-degree programs. Some universities offer accelerated pathways that allow students to complete bachelor's and master's degrees in approximately five years.1
If you pursue PE licensure, you'll need additional time. State licensing requirements typically include several years of qualifying professional experience in addition to the required examinations.
A master's degree is not necessary for most entry-level mechanical engineering positions, but it can deepen your expertise as you prepare for more advanced work. Full-time, part-time and online graduate programs offer different schedules, so you can select an approach that fits your employment and personal commitments.
Essential Skills for a Mechanical Engineering Career
Mechanical engineering requires more than knowledge of mathematical formulas and physical principles. You must apply that knowledge to real problems, evaluate competing design considerations and work effectively with other professionals.
Technical and Analytical Skills
You'll use a range of technical tools and methods to design, analyze and improve products and systems.
Important capabilities include:
- Computer-aided design (CAD): Creating and modifying digital models of mechanical components and assemblies
- Mathematical modeling: Representing physical systems through equations and computational methods to predict performance
- Engineering analysis and simulation: Evaluating factors such as stress, vibration, fluid flow and thermal behavior before physical testing
- Materials evaluation: Selecting materials based on mechanical properties, operating conditions, performance and cost
- Testing and data analysis: Interpreting experimental results, identifying problems and refining engineering designs
As technologies evolve, your understanding of both established engineering principles and developments in automation, robotics, advanced manufacturing and computational methods will help you evaluate their practical applications.
Problem-Solving, Communication and Collaboration
Technical expertise is essential, but engineering problems rarely exist in isolation. A proposed design may need to satisfy performance requirements while accounting for manufacturing constraints, cost, safety, maintenance and the needs of its intended users. You'll need to evaluate those competing considerations and explain the reasoning behind your decisions.
Effective communication is especially important when you collaborate with colleagues in electrical engineering, software development, manufacturing, product management and other disciplines.
You'll also need to document your work clearly, interpret feedback and explain complex information to audiences without the same technical background. As your responsibilities expand, leadership and project coordination skills can become equally important. You may oversee technical teams, guide design decisions or help organizations evaluate the feasibility of new technologies.
Expand Your Expertise to Take on Greater Engineering Challenges
Mechanical engineers often work on problems that involve several interconnected systems, competing design requirements and technologies outside their immediate areas of expertise.
Case Western Reserve University's online MS in Mechanical Engineering program is designed to develop a strong working command of the discipline.
