Mechanical Engineering Intern information

What are the key skills and qualifications needed to thrive as a mechanical engineering intern, and why are they important?

To thrive as a Mechanical Engineering Intern, you need a solid grasp of engineering fundamentals, problem-solving abilities, and coursework in mechanical design or analysis, often supported by progress toward a relevant engineering degree. Familiarity with CAD software (such as SolidWorks or AutoCAD), simulation tools, and basic lab equipment is typically required. Strong communication, teamwork, and a willingness to learn help interns adapt quickly and contribute effectively to projects. These skills and qualities are important to ensure interns can support engineering teams, apply theory to real-world challenges, and grow within the profession.

What does a mechanical engineering intern do?

As a mechanical engineering intern, you prepare calculations and reports, gain experience with engineering systems, integrate tracking plans, and perform analysis of mechanical design choices. You may help test products, interact with various members of a project team, and create or modify CAD models. As an intern, your responsibilities are limited, and most employers consider gaining experience to be the most important part of your job. Many mechanical engineering interns focus on building professional relationships in the hope of landing a permanent job after graduating. You may need to develop your skills in engineering, CAD software, and prototyping during your internship.

What types of projects do mechanical engineering interns typically work on, and how much hands-on experience can I expect?

As a Mechanical Engineering Intern, you'll often assist with a mix of design, analysis, and testing projects under the guidance of experienced engineers. Interns commonly use CAD software to create or modify designs, help with prototype assembly, perform basic calculations, and assist in conducting experiments or tests. You can expect significant hands-on experience, especially in labs or on the shop floor, learning how theoretical concepts are applied in real-world engineering tasks. Collaboration with cross-functional teams, such as manufacturing or quality assurance, is typical, providing valuable exposure to the entire product lifecycle.

Which internship is best for mechanical engineering students?

The best internship for mechanical engineering students typically involves roles in manufacturing, design, or research and often requires proficiency in CAD software, problem-solving skills, and understanding of engineering principles. Internships at manufacturing firms, automotive companies, or aerospace organizations provide practical experience and industry exposure valuable for career development.

What does a mechanical engineering intern do?

A Mechanical Engineering Intern assists engineers in designing, developing, and testing mechanical devices and systems. They typically work on tasks such as creating CAD drawings, conducting research, performing calculations, and helping with prototype assembly or testing. Interns gain hands-on experience by supporting ongoing projects and collaborating with other engineers and technicians. This role provides valuable exposure to real-world engineering challenges and helps students apply their academic knowledge in a practical setting.

Job description

About the Position: Serves as Engineering Division's Senior Engineering Technical Lead (ETL) for OCONUS projects related to Water Resources in Latin America and coordinates the planning and implementation of tasks, products, and related efforts in support of delivering the projects in accordance with international agreements. Advises customer on how best to achieve solutions to technically complex water resource problems. Position may be made permanent without further competition.Qualifications:Who May Apply: Only applicants who meet one of the employment authority categories below are eligible to apply for this job. You will be asked to identify which category or categories you meet, and to provide documents which prove you meet the category or categories you selected. See Proof of Eligibility for an extensive list of document requirements for all employment authorities.
  • Current Department of Army Civilian Employees Applying on Time-Limited Assignments

In order to qualify, you must meet the education and/or experience requirements described below. Experience refers to paid and unpaid experience, including volunteer work done through National Service programs (e.g., Peace Corps, AmeriCorps) and other organizations (e.g., professional; philanthropic; religious; spiritual; community; student; social). You will receive credit for all qualifying experience, including volunteer experience. Your resume must clearly describe your relevant experience; if qualifying based on education, your transcripts will be required as part of your application. Additional information about transcripts is in this document.

Basic Requirement for Lead Civil Engineer:
A. Degree: Bachelor's degree (or higher degree) in engineering. To be acceptable, the program must: (1) lead to a bachelor's degree (or higher degree) in a school of engineering with at least one program accredited by the Accreditation Board for Engineering and Technology (ABET); OR (2) include differential and integral calculus and courses (more advanced than first-year physics and chemistry) in five of the following seven areas of engineering science or physics: (a) statics, dynamics; (b) strength of materials (stress-strain relationships); (c) fluid mechanics, hydraulics; (d) thermodynamics; (e) electrical fields and circuits; (f) nature and properties of materials (relating particle and aggregate structure to properties); and (g) any other comparable area of fundamental engineering science or physics, such as optics, heat transfer, soil mechanics, or electronics.
OR
B. Combination of Education and Experience: College-level education, training, and/or technical experience that furnished (1) a thorough knowledge of the physical and mathematical sciences underlying engineering, and (2) a good understanding, both theoretical and practical, of the engineering sciences and techniques and their applications to one of the branches of engineering. The adequacy of such background must be demonstrated by one of the following:
1. Professional registration or licensure - Current registration as an Engineer Intern (EI), Engineer in Training (EIT), or licensure as a Professional Engineer (PE) by any State, the District of Columbia, Guam, or Puerto Rico. Absent other means of qualifying under this standard, those applicants who achieved such registration by means other than written test (e.g., State grandfather or eminence provisions) are eligible only for positions that are within or closely related to the specialty field of their registration. For example, an applicant who attains registration through a State Board's eminence provision as a manufacturing engineer typically would be rated eligible only for manufacturing engineering positions.
2. Written Test - Evidence of having successfully passed the Fundamentals of Engineering (FE) examination, or any other written test required for professional registration, by an engineering licensure board in the various States, the District of Columbia, Guam, or Puerto Rico.
3. Specified academic courses - Successful completion of at least 60 semester hours of courses in the physical, mathematical, and engineering sciences and that included the courses specified in A above. The courses must be fully acceptable toward meeting the requirements of an engineering program.
4. Related curriculum - Successful completion of a curriculum leading to a bachelor's degree in an appropriate scientific field, e.g., engineering technology, physics, chemistry, architecture, computer science, mathematics, hydrology, or geology, may be accepted in lieu of a degree in engineering, provided the applicant has had at least 1 year of professional engineering experience acquired under professional engineering supervision and guidance. Ordinarily there should be either an established plan of intensive training to develop professional engineering competence, or several years of prior professional engineering-type experience, e.g., in interdisciplinary positions.
In addition to meeting the basic requirement above, to qualify for this position you must also meet the qualification requirements listed below:

  • one year of specialized experience equivalent to the GS-13 grade level in the Federal service which includes: serving as a technical expert and team leader for complex civil engineering projects.
