Intern Engineer information

What does an intern engineer do?

An Intern Engineer is a student or recent graduate who works under the supervision of experienced engineers to gain practical experience in their field. Their responsibilities typically include assisting with technical projects, conducting research, analyzing data, preparing reports, and learning industry-specific tools and software. Intern Engineers gain hands-on experience, develop professional skills, and often contribute to real-world engineering solutions while preparing for a future full-time role in engineering.

What types of projects or tasks are typically assigned to intern engineers, and how do these contribute to their learning and professional development?

Intern Engineers are often assigned a mix of hands-on technical tasks and supportive project work, such as assisting with design, testing prototypes, conducting research, or updating documentation. These tasks are designed to expose interns to real-world engineering challenges while allowing them to learn from experienced professionals. Interns frequently collaborate with engineers, project managers, and cross-functional teams, gaining insight into industry practices and teamwork. This practical experience not only builds technical skills but also helps interns develop communication, problem-solving, and project management abilities that are valuable for future career growth.

What are the key skills and qualifications needed to thrive as an intern engineer, and why are they important?

To thrive as an Intern Engineer, you typically need a foundational understanding of engineering principles, problem-solving abilities, and progress toward a relevant engineering degree. Familiarity with industry-standard software such as AutoCAD, MATLAB, or SolidWorks, along with basic knowledge of project management tools, is often expected. Strong communication, eagerness to learn, and teamwork set standout interns apart in fast-paced environments. These skills and qualities enable interns to contribute effectively, adapt to real-world challenges, and maximize their learning during the internship.

What is the difference between Intern Engineer vs Junior Engineer?

  • Veterans Employment Opportunity Act (VEOA) of 1998


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 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-11 grade level in the Federal service which includes applying professional civil engineering theories, principles, and practices to manage construction projects. This experience includes: 1) Performing reviews of construction project design packages, plans, and specifications to ensure completeness and constructability; 2) Serving as a technical advisor on construction projects, providing recommendations on materials, methods, and solutions for complex engineering problems; 3) Administering construction contracts, which includes reviewing change orders, contractor claims, and pay estimates to ensure compliance with contract requirements; 4) Coordinating with stakeholders (e.g., A/E firms, contractors, government agencies) to resolve construction-related issues and ensure project objectives are met.


Time in Grade Requirement: Applicants who have held a General Schedule (GS) position within the last 52 weeks must have 52 weeks of Federal service at the next lower grade or equivalent (GS-11).

Education:FOREIGN EDUCATION: If you are using education completed in foreign colleges or universities to meet the qualification requirements, you must show the education credentials have been evaluated by a private organization that specializes in interpretation of foreign education programs and such education has been deemed equivalent to that gained in an accredited U.S. education program; or full credit has been given for the courses at a U.S. accredited college or university.
