Junior mechanical engineers test, build, and develop mechanical devices of all types, including machines, engines, and tools. They usually work day hours in a lab or office environment. However, some on-site and weekend work may be required to complete necessary tasks and meet deadlines. Junior mechanical engineers are considered entry-level employees and usually report to senior mechanical engineers.

Junior Mechanical Engineer Duties and Responsibilities

Junior mechanical engineers are responsible for isolating and fixing problems as well as creating and designing brand-new products, machines, and tools. They complete the following duties on a regular basis:

Create Mechanical Designs and Drawings

The junior mechanical engineer creates highly detailed design schematics for various components of a project.

Write Precise Calculations

The first part of any mechanical engineering project often begins on paper. This requires writing out precise calculations before any hands-on mechanical work begins.

Test Products for Functionality

Calculations must be tested and retested to isolate problems with mechanical equipment. The junior mechanical engineer must re-engineer products when problems are found and recalculate to return products to full functionality.

Prepare Reports for Senior Engineers

Junior mechanical engineers report to senior mechanical engineers, creating detailed reports and summaries of ongoing projects to keep their supervisors up-to-date.

Collaborate with Engineering Team

Junior mechanical engineers may complete some projects alone, but in most cases they work as part of an engineering team. This requires frequent communication and daily collaboration to make sure all aspects of the project are being addressed, and to ensure that no one is working on the same problem at the same time.

Junior Mechanical Engineer Skills and Qualifications

Junior mechanical engineers are precise and detail-oriented, but they must also be capable of creative thinking and problem-solving. They need several skills to perform their daily responsibilities:

  • Software proficiency - junior mechanical engineers perform many tasks on the computer using specialized design software
  • Communication skills - because this is a collaborative position, it's necessary for junior mechanical engineers to clearly communicate with the rest of the engineering team and to actively listen to problems expressed by others
  • Attention to detail - junior mechanical engineers may look through hundreds of lines of computer code and design schematics to isolate problems, which requires strong focus
  • Patience - isolating problems can be a lengthy and frustrating process, so remaining patient and calm is essential
  • Creativity - junior mechanical engineers must design and develop brand-new machinery and tools, which requires creativity and the ability to visualize new projects

Junior Mechanical Engineer Tools of the Trade

Junior mechanical engineers work daily with computer programs, design schematics, and machinery, including:

Engineering software (AutoCAD or similar programs)

Mechanical schematics


Protective equipment (safety glasses, work boots, hard hats, and gloves)

Junior Mechanical Engineer Education and Training

Junior mechanical engineers need a bachelor’s degree in mechanical engineering. After one to two years of working on projects for the same company, they’re often eligible for promotion to a senior mechanical engineer position. Obtaining a master’s degree in mechanical engineering can increase the chances of receiving this promotion, but most companies do not require additional schooling.

Junior Mechanical Engineer Salary and Outlook

Data from the Bureau of Labor Statistics shows that mechanical engineers earn around $41,506 to $74,003 annually, and often earn extra money through bonuses and profit-sharing programs. The median pay for mechanical engineers is $84,190 per year. There were 288,800 mechanical engineering jobs available in 2016, and through 2026 job growth is estimated at 9 percent, which is the national average.

Junior mechanical engineers receive health insurance and retirement benefits in addition to a regular salary, with promotional opportunities available. Regular vacation time and paid leave are also available, and some companies may offer additional perks such as continuing education.
