Mechanical engineers are the masterminds behind machines and mechanical systems that power our world and solve complex engineering challenges. They are the architects of everything from powerful engines and efficient HVAC systems to life-saving medical devices and the vehicles we rely on daily.
Mechanical engineering is deeply interwoven into the fabric of our daily lives, influencing the buildings we inhabit, the transportation we use, the food we consume, and even the tools we employ in our kitchens. But if you’re asking, “what does a mechanical engineer really do?”, the answer is multifaceted and varies across industries and companies.
According to Jennifer McInnis, a faculty member at Southern New Hampshire University’s (SNHU) mechanical engineering program, mechanical engineering job descriptions are incredibly diverse, opening up a wide array of career paths for those with the right education. Mechanical engineers are often at the forefront of design, creating machinery ranging from intricate engines and comprehensive heating, ventilation, and air conditioning (HVAC) systems to essential infrastructure like elevators and escalators, as highlighted by the U.S. Bureau of Labor Statistics (BLS). They also play a critical role in the development and production of a vast range of products, from advanced medical equipment to the automobiles that shape our commutes (BLS).
“Mechanical engineers could be involved in analysis, developing systems, predicting performance outcomes, or diagnosing operational behaviors,” McInnis explains. “Some might manage large-scale systems, considering the interplay of numerous factors, while others focus on the intricate design of individual components.”
Decoding Mechanical Engineering: More Than Just Machines
“At its core, mechanical engineering is about problem-solving,” McInnis emphasizes. “It’s the practical application of scientific principles, mathematical rigor, and specialized knowledge to engineer effective solutions to real-world problems.”
Mechanical engineering stands out as one of the most encompassing branches of engineering. It encompasses the complete lifecycle of mechanical devices and systems, from initial research and innovative design to meticulous construction and rigorous testing. This broad field includes an array of tools, powerful engines, and complex machines, as detailed by the BLS.
If a career in mechanical engineering resonates with you, pursuing a robust mechanical engineering education is a crucial next step.
Exploring Career Horizons with a Mechanical Engineering Degree
A degree in mechanical engineering is a passport to a diverse spectrum of industries, spanning from the automotive sector and large-scale construction to cutting-edge information technology, the rapidly evolving biomedical field, and advanced manufacturing.
The field of mechanical engineering is continually expanding, driven by technological advancements, leading to the emergence of exciting and novel career paths for skilled and educated professionals.
If you’re considering entering this dynamic field, you might wonder about the competitiveness and the initial challenges. A strong aptitude for math and science is fundamental. The BLS confirms that most mechanical engineering positions require a bachelor’s degree in engineering as a prerequisite for entry into the profession (get started in the industry).
BLS projections indicate a stable growth in employment for mechanical engineers, with a 2% increase expected through 2031, translating to over 6,400 new positions. Given the continuous innovation in technology and industrial endeavors, career opportunities in mechanical engineering are poised for ongoing expansion.
Earning a bachelor’s degree in mechanical engineering is a vital first step towards capitalizing on this expanding job market, according to McInnis. For those aiming for specialization within mechanical engineering or leadership roles, a master’s degree can provide a significant competitive advantage.
For instance, McInnis suggests that a mechanical engineer might enhance their career prospects by pursuing an MBA in Project Management. In today’s economy, project management skills are increasingly valued, with a high demand for professionals who can ensure projects are completed on time and within budget, as noted by the American Society of Mechanical Engineers (ASME).
By integrating project management expertise with their engineering skills, mechanical engineers can effectively oversee manufacturing, construction, and other complex engineering projects, ensuring efficiency and cost-effectiveness.
Where Mechanical Engineers Make a Difference: Diverse Work Environments
The breadth of mechanical engineering opens doors to numerous specialized types of engineering roles. Here are some key mechanical engineer job roles:
