What Do Mechanical Engineers Do?

Mechanical engineers are the innovators behind a vast range of systems and devices that power our everyday lives. They design, build, and improve everything from engines and generators to air conditioning systems and robotics. Their work often begins with analyzing a problem and developing solutions through prototype design and testing.

Mechanical engineers also play a key role in industries such as automotive, manufacturing, and renewable energy. As problem solvers, they help advance society’s infrastructure. In fact, engineering itself is fundamental to society’s progress, as explored in this article on the importance of engineering in our daily lives. Their expertise ensures that machines run efficiently, integrating mechanical, electrical, and thermal elements into cohesive systems that we depend on.

Educational Requirements for Mechanical Engineers

To become a mechanical engineer, a bachelor’s degree in mechanical engineering or mechanical engineering technology is essential. Accredited programs cover fundamental topics like mathematics, physics, and engineering principles, alongside specialized courses in thermodynamics, fluid mechanics, and machine design. Many programs offer hands-on experience through internships or cooperative education programs, giving students practical insights into the field.

Additionally, to become licensed, many engineers complete the Fundamentals of Engineering (FE) exam, which is often followed by the Professional Engineer (PE) exam after gaining work experience.

How to Become a Licensed Professional Mechanical Engineer

Becoming a licensed Professional Engineer (PE) is a significant milestone for mechanical engineers, especially those looking to advance their careers or take on leadership roles. The process begins with earning a bachelor’s degree from an ABET-accredited program. After graduation, aspiring engineers must pass the Fundamentals of Engineering (FE) exam, which certifies them as an Engineer-in-Training (EIT) or Engineer Intern (EI). It’s important to have a proper engineering degree from an accredited university.

Once you’ve gained a minimum of four years of supervised work experience, you’re eligible to take the PE exam. This rigorous test evaluates your competence and ability to practice mechanical engineering at a professional level. Upon passing, you’ll receive your PE license, allowing you to legally offer engineering services to the public, take on more responsibility in your projects, and open doors to new career opportunities.

Licensure isn’t just about following regulations – it’s a mark of distinction that showcases your expertise and commitment to the field. It also ensures you meet the ethical and technical standards necessary for protecting public safety, which is at the core of every engineering discipline.

Mechanical Engineer Salaries and Earning Potential

Mechanical engineering offers a strong earning potential, with salaries varying based on factors such as industry, location, and level of experience. According to recent data, the median annual wage for mechanical engineers in the U.S. is around $99,500. Entry-level positions typically offer competitive starting salaries, and as engineers gain experience, especially with a Professional Engineer (PE) license, their earning potential significantly increases. Those working in specialized sectors, such as oil and gas or advanced manufacturing, often earn higher-than-average wages.

With opportunities to work across diverse industries, mechanical engineers enjoy robust career growth, and further education or certifications can open the door to even higher earning potential.

The following table provides a breakdown of salary information for mechanical engineers based on recent jobs data:

These figures show significant earning potential, especially for those working in specialized industries such as oil and gas or cutting-edge technology fields. The highest salaries are found in states like Alaska and California, reflecting the demand and cost of living in these regions​.

Career Path and Advancement Opportunities

Mechanical engineers enjoy a wide range of career paths and advancement opportunities. Early in your career, you may start as an entry-level engineer, working on design, testing, or production. Over time, with experience and continued education, you can take on more responsibilities, leading to roles such as project manager, team leader, or department head. A Professional Engineer (PE) license is a critical milestone for career advancement, enabling you to oversee public projects, sign off on designs, and lead engineering teams.

For those interested in more specialized fields, additional certifications in areas like HVAC systems, automotive design, or robotics can further enhance career prospects. Mechanical engineers can also transition into senior roles such as engineering directors, consultants, or technical experts in niche industries.

Further education, such as a master’s degree or MBA, can lead to executive positions, including Chief Engineer or even roles in management, blending engineering expertise with business acumen. Mechanical engineers who remain engaged in ongoing learning and adapt to emerging technologies, like renewable energy or automation, will find numerous opportunities to grow throughout their careers​.

The Licensing Challenge: Passing the Engineering Exam

When you start your career path as an aspiring mechanical engineer, you’ll correctly focus on getting that crucial degree. But a diploma doesn’t make you a licensed professional engineer. Becoming a true professional engineer requires navigating a multi-stage process governed by your state board.

The first major hurdle is the Fundamentals of Engineering Exam (FE Exam). This comprehensive engineering exam validates your foundational technical knowledge. Passing the FE allows you to become an Engineer in Training (EIT), which is your formal entry into the post-graduate licensing process. We see too many talented individuals delay this step, but I can’t stress enough how vital it is. You’ll find that many of the best job opportunities and accelerated career tracks within engineering firms are reserved for those who have at least attained EIT status.

The ultimate goal, of course, is attaining your engineer license – the Professional Engineer (PE) credential. Achieving your PE requires meeting licensing requirements that typically include passing a second, more difficult principles and practice of engineering exam (the PE Exam). This credential is required for holding responsible charge of engineering projects and is the key differentiator for engineering managers and principals in the engineering field.

Beyond the Classroom: Why Work Experience Defines Your Mechanical Skills

While securing a four-year degree in mechanical engineering is your foundation, the true test of your competency lies in work experience. This is where your classroom knowledge transforms into practical, marketable skills mechanical employers are looking for.

In the engineering field, the importance of supervised, professional work cannot be overstated. You’ll need specific experience to sit for the final engineering exam. This work experience – typically four years under the direct supervision of a licensed PE – is often the longest, most challenging phase of the entire career path. This practical, hands-on training teaches you the non-academic aspects of the job: project management, budget control, and compliance. We look for candidates who have taken initiative early in their career by pursuing summer internships or co-op programs; that kind of experience demonstrates true commitment to the profession. It proves that you’ve got the skills necessary to succeed when the complexity of real-world systems comes into play.

Final Take – Get Your Engineer License

Becoming a mechanical engineer is a rewarding journey filled with opportunities for growth, innovation, and professional advancement. With a solid educational foundation, key technical and analytical skills, and the pursuit of licensure, mechanical engineers can make a significant impact across various industries. Whether you’re designing cutting-edge technologies or leading engineering teams, the field offers diverse career paths that can lead to leadership roles or specialization in advanced sectors. Continuous learning and adaptability are key to long-term success in this ever-evolving profession.
