Mechanical Engineers
What they do
Perform engineering duties in planning and designing tools, engines, machines, and other mechanically functioning equipment. Oversee installation, operation, maintenance, and repair of equipment such as centralized heat, gas, water, and steam systems.
Kinds of work
- Realistic: Hands-on work with tools, machines, plants or animals, often outdoors.
- Investigative: Science, research, figuring out how things work and solving complex problems.
- Conventional: Organizing information, following clear procedures and working with data and details.
Moderate pressure: How much pressure workers in this job report: deadlines, conflict, dealing with upset people, the cost of mistakes, responsibility for others' safety, competition and long hours. It varies a lot from one employer to the next. Source: U.S. Department of Labor worker surveys.

Career path
How people usually get into this career, from school to their first job and beyond.
Mechanical engineering is not usually a straight-out-of-school job. Most people earn a bachelor's degree, then spend about 2 to 4 years in an entry-level engineering role before taking on the full Mechanical Engineer title.
High school math and physics, then a Bachelor's degree in Mechanical Engineering
4-5 yearsYou learn the design, materials, heat, and motion skills the job uses every day, and most employers require this degree.
Junior Mechanical Engineer
2-4 yearsYou work under senior engineers on design, testing, and equipment support, building the hands-on experience employers expect before giving you full responsibility.
Mechanical Engineer
OngoingYou plan and design tools, engines, machines, and building systems, and you oversee their installation, operation, maintenance, and repair.
Where it can lead
Senior Mechanical Engineer
3-5 years of experience firstYou lead larger projects, mentor junior engineers, and make more of the design decisions, which usually comes from a track record of solid independent work.
Engineering Manager
5+ years of experience firstYou shift from hands-on design toward leading a team, planning budgets and schedules, and making decisions about projects, so strong communication and leadership matter as much as technical skill.
What you can do now
Ideas for high school and college students.
In high school
- Take advanced math and physicsCalculus and physics are the core skills you will use in every mechanical engineering class.
- Join a robotics, STEM, or science fair clubBuilding and testing real machines teaches design thinking and teamwork, which engineers use all the time.
- Learn basic CAD or drawing softwareMany schools offer drafting or CAD classes, and early practice makes university engineering courses easier.
- Get a starter job or volunteer at a workshop, garage, or hardware storeWorking with tools and fixing things builds practical intuition about how machines actually work.
- Explore engineering summer programs at a local college or community centerHands-on summer activities help you test whether engineering fits you before you commit to a major.
In college
- Major in mechanical engineering and stay on track with the math sequenceA accredited mechanical engineering degree is the usual entry requirement for this career, so every course in the sequence matters.
- Get an engineering internship or co-opReal work experience during school is one of the strongest ways to prepare for the 2 to 4 years of entry-level experience employers look for.
- Join a student engineering club or design teamTeams like Formula-style racing, robotics, or senior design projects let you practice teamwork, budgets, and building real prototypes.
- Work a campus job in a lab, machine shop, or maker spaceHands-on lab work builds the testing and troubleshooting skills you will use on the job.
- Learn CAD and basic programming, such as MATLAB or PythonEngineers use these tools for analysis and design, and having them early makes you more competitive for internships.
Tips for getting started
- Take the hardest math and physics classes your school offers, since they are the foundation for an engineering degree.
- Look for internships or co-op programs in manufacturing, HVAC, or product design; hands-on experience makes your résumé stand out when you apply for entry-level jobs.
- Learn CAD software (such as free student versions of common design programs) and practice explaining your projects clearly, because engineers use both every day.
