Job Description

Summary

This job involves conducting precise tests to measure the hardness of materials using global standards and representing the US in international committees that set those standards.

It's a role at a government science agency focused on advancing technology and innovation.

A good fit would be someone with an engineering background who enjoys detailed lab work and collaborating on worldwide technical guidelines.

Key Requirements

  • Bachelor's degree in engineering from an ABET-accredited program, or equivalent combination of education and experience demonstrating engineering knowledge
  • At least one year of specialized experience equivalent to GS-9 level in mechanical testing or related engineering fields
  • Thorough understanding of physical and mathematical sciences underlying engineering
  • Knowledge of international standards for hardness measurements
  • Ability to perform hardness measurements following standard methods
  • Experience or eligibility for professional engineering registration (e.g., PE, EIT, or passing FE exam)
  • U.S. citizenship and ability to work in Gaithersburg, Maryland

Full Job Description

NIST works with industry and science to advance innovation and improve quality of life.

We're looking for a Mechanical Testing Engineer to join our team, to perform hardness measurements following international standard methods and act as a US representative on international standards committees for hardness measurement.

This notice is issued under direct-hire authority to recruit new talent to occupations for which NIST has a severe shortage of candidates. Basic Requirements:A. 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) (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)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.) AND In addition to the basic requirements listed above applicants must also possess 1 year (52 weeks) of specialized experience equivalent to at least the GS-9 grade level (ZP-II at NIST).Specialized experience is defined as: Experience making hardness measurements using the Rockwell method and either Vickers or Brinell methods Preparing hardness block Standard Reference Materials (SRMs) Performing instrumented indentation testing Participation in international SDO committees related to hardness measurements.

OR Master's or equivalent graduate degree as defined in the basic requirements. OR A combination of graduate education and specialized experience as defined in the additional requirements.

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).

Volunteer work helps build critical competencies, knowledge, and skills and can provide valuable training and experience that translates directly to paid employment.

You will receive credit for all qualifying experience, including volunteer experience. The qualification requirements in this vacancy announcement are based on the U.S.

Office of Personnel Management (OPM) Qualification Standards Handbook.

If requesting reconsideration of your qualification determination, please refer to the following site: Applicant Reconsideration Major Duties:

  • In this position, you will: Perform hardness measurements following international standard methods and assess uncertainties Certify the use of hardness Reference Materials Act as a US representative on international standards committees for hardness measurement Participate in International Key Comparisons of hardness measurements and perform research with the aims of increasing the scope of Reference Material offerings, Measurement Service offerings Improving the scientific understanding of hardness indentation processes For example, design and analysis of instrumented indentation experiments.
