Job description

See below for important information regarding this job.
Additional vacancies may be filled from this announcement.Qualifications:To qualify for an Interdisciplinary Engineer position your resume and supporting documentation must support:
A. Basic Requirement:
A Bachelor's Degree or higher in professional engineering. To be acceptable, the program must: (1) be in a school of engineering with at least one program accredited by the Accreditation Board for Engineering and Technology (ABET) as a professional engineering curriculum; 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
A 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 professional 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, 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 in engineering that included the courses specified in the Basic Requirements above. The courses must be fully acceptable toward meeting the requirements of a professional engineering curriculum as described in the Basic Requirements above.
  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.
AND
C. Specialized Experience: In addition to the basic requirement above, you must possess one year of specialized experience that equipped you with the competencies to successfully perform the duties of the position and is directly in or related to this position. To qualify for the NH-03 level, specialized experience must be at the NH-02 or GS-11 grade level or equivalent under other pay systems in the Federal service, military, or private sector.Creditable specialized experience includes:
  • Applying engineering and analysis principles, concepts, and standards in support of complex defense acquisition systems.
  • Performing oversight of the Systems Engineering Development Life Cycle for major Acquisition programs and provide technical support pertaining to missile systems and sensor technologies.
  • Conducting reviews of contracts and in conducting reviews of contractor performance; proposing and providing technical advice on changes relating to contract applications/developments.
  • Leadership capacity conducting engineering and analytical surveillance on substantive/critical and unique changes of advanced engineering functions implementing agency policy, and new/developmental processes.
Education:

Substitution of education may not be used in lieu of specialized experience for this grade level.
If the position has a minimum education requirement you MUST provide transcripts (unofficial are acceptable at the time of application) to support your educational claims. Or, if you are using education to qualify in lieu of specialized experience you MUST provide transcripts (unofficial are acceptable at the time of application) to support your educational claims. The transcripts must include your name, the name of the college or university, class/course list, completed number of credits/hours, and the date degree conferred (if applicable). Education must be accredited by an accrediting institution recognized by the U.S. Department of Education. Licenses must be current at time of application.

GRADUATE EDUCATION: One academic year of graduate education is considered to be the number of credits hours that 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.
FOREIGN EDUCATION: If you are using education completed in foreign colleges or universities to meet the qualification requirements, 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.
