Internship Mechanical Engineer Jobs in Oak Ridge, TN

Are you ready to help shape America's energy future?

The Department of Energy (DOE) is looking for motivated, forward-thinking individuals to join our Power Up Program. This internship gives you hands-on work experience, direct mentorship, and professional networking opportunities within the federal government.

**Please note these series do have Basic Education Requirements that MUST be met and are listed in the Education section of the vacancy announcement. There is one for the 0801 series and one for the 1301 series.**
You must meet all qualifications and eligibility requirements by the closing date (09/04/2026) of this announcement.

For the GS-09: You must have one year of specialized experience at a level of difficulty and responsibility equivalent to the GS-07 grade level in the Federal Service. Specialized experience for this position at the GS-9 includes:

• Conducting laboratory experiments, field tests, or site walks to collect physical data, monitor equipment, and analyze scientific/engineering metrics (such as design plans, environmental data, or lab samples).; AND
• Reviewing engineering or scientific technical documents, reports, and procedures under the guidance of senior staff to identify discrepancies, safety hazards, or compliance issues.

OR YOU MAY QUALIFY FOR THE GS-9 BASED ON EDUCATION: 2 years of progressively higher-level graduate education leading to a master's degree or master's or equivalent graduate degree. Graduate education must provide the knowledge, skills, and abilities to perform in the position. Please see the information under Education.
OR YOU MAY QUALIFY FOR THE GS-9 BASED ON COMBINATION OF EDUCATION/EXPERIENCE: If you have some qualifying education and some qualifying experience, but don't fully meet either requirement on its own, you may be able to combine them. Only graduate education in excess of one year (18 semester hours or equivalent) can be used in this calculation. Experience must be reflected in your resume, and transcripts are required.

1. Divide your qualifying graduate semester hours beyond the first 18 by 18. That gives you your education percentage.
2. Divide your months of qualifying experience by 12. That gives you your experience percentage.
3. Add the two together. If the total is 100% or more, you qualify.

Experience may include paid or unpaid work, including internships, volunteer service, student leadership, military service, apprenticeships, or other relevant activities. Resumes must clearly describe duties, dates, and hours worked per week.
Note about Graduate Education: One academic year of graduate education is considered to be the number of credits hours your graduate school has determined to represent one academic year of full-time study. Such study may have been performed on a full-time or part-time basis. If you cannot obtain your graduate school's definition of one year of graduate study, 18 semester hours (or 27 quarter hours) should be considered as satisfying the requirement for one year of full-time graduate study.
Education must be accredited by an accrediting institution recognized by the U.S. Department of Education in order for it to be credited towards qualifications; applicants' resumes and supporting documentation should only reflect education received from schools accredited by such institutions. Applicants can verify accreditation at the following website: https://ope.ed.gov/dapip/#/home.If a relevant course is not clearly qualifying (e.g., special topic, seminar, research, thesis, obscure or misleading course title, etc.), please submit an official course syllabus and/or detailed course description from the university/college for that particular course to ensure you are properly evaluated. Provide all relevant transcripts, not just your most recent one.
Special Instructions for Foreign Education: If you are using education completed in foreign colleges or universities to meet Minimum Qualifications, you must show that 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. Failure to provide such documentation with your application will result in lost consideration.

You must meet the following Basic Education Requirement listed below in order to qualify for the 0801 series:
Degree: Engineering. To be acceptable, the program must:
(1) lead to a bachelor's degree in a school of engineering with at least one program accredited by 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 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)1, 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)2 examination or any other written test required for professional registration by an engineering licensure board in the various States, the District of Columbia, Guam, and 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 the basic requirements under paragraph A. The courses must be fully acceptable toward meeting the requirements of an engineering program as described in paragraph A.
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 bachelor's 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. (The above examples of related curricula are not all-inclusive.)

1. Successful completion of a full 4-year course of study in an accredited college or university leading to a Bachelor's degree or higher in physical science, engineering, or mathematics that included 24 semester hours in physical science and/or related engineering science such as mechanics, dynamics, properties of materials, and electronics.; OR
2. Combination of education and experience -- education equivalent to one of the majors shown above that included at least 24 semester hours in physical science and/or related engineering science, plus appropriate experience or additional education.
