These positions are in the Defense Technologies Engineering Division (DTED), within the Engineering Directorate.
These positions will be filled at either the SES.2 or SES.3 level depending on your qualifications. Additional job responsibilities (outlined below) will be assigned if you are selected at the higher level.
- Conduct tests on mechanical and/or diagnostic systems, analyze results, and author reports, under limited direction.
- Conduct experimental modal analyses and correlate results with dynamic finite element (FE) models.
- Operate test equipment (shaker systems, shock machines, thermal chambers, etc.) using fundamental knowledge of best test and measurement practices.
- Prepare supporting safety and engineering documentation and participate in formal engineering design reviews.
- Perform supporting engineering calculations for structural, thermal, and diagnostic systems.
- Participate in the detail design process, component part fabrication, and unit assembly.
- Provide solutions to problems of limited complexity that require the evaluation of readily identifiable factors using standard techniques and methodologies.
- Interface with peers both internal and external to the organization to complete various tasks.
- Perform other duties as assigned.
In Addition at the SES.3 Level
- Guide the completion of projects and conduct technical tasks and/or set specific technical strategy and direction for self and/or others.
- Work as a technical expert on a multidisciplinary team and monitor or direct activities of technical staff as lead of a technical project.
- Represent the organization as the primary technical contact on tasks and projects.
- Bachelor's degree in Mechanical Engineering or related field, or the equivalent combination of education and related experience.
- Comprehensive knowledge and/or experience in one or more of the following areas: vibration and shock measurements, experimental modal and dynamic analysis, general instrumentation (i.e. accelerometers, strain gages, thermo-couples, resistance thermal detectors (RTD’s), capacitance gages, laser vibrometers, pressure sensors, etc.), general data acquisition theory (Nyquist criterion, anti-aliasing, etc.).
- Comprehensive knowledge of experimental modal and dynamic analyses, testing practices, and data processing.
- Comprehensive knowledge of engineering hardware design and fabrication.
- Comprehensive knowledge of and/or experience with design principles.
- Experience using Matlab programming and data analysis including use of digital filters and when to apply them.
- Ability to work effectively in a multidisciplinary team and government regulated environment.
- Proficient verbal and written communication skills necessary to effectively collaborate in a team environment and present and explain technical information.
In Addition at the SES.3 Level
- Advanced knowledge of measurement sensors and an understanding of when to use specific sensors for certain applications.
- Advanced verbal and written communication skills necessary to effectively collaborate in a team environment, present and explain technical information, and provide advice to managment.
- Experience with environment definition and test specification development.
- Master's degree or PhD in Mechanical Engineering.
- Knowledgeable in the use and operation of laser doppler vibrometry systems.
- Proficient in operating and interpreting data from mechanical load frames.
Pre-Placement Medical Exam: A job related pre-placement medical examination may be required.
Pre-Employment Drug Test: External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test. This includes testing for use of marijuana as Federal Law applies to us as a Federal Contractor.
Security Clearance: This position requires a Department of Energy (DOE) Q-level clearance.
If you are selected, we will initiate a Federal background investigation to determine if you meet eligibility requirements for access to classified information or matter. In addition, all L or Q cleared employees are subject to random drug testing. Q-level clearance requires U.S. citizenship. If you hold multiple citizenships (U.S. and another country), you may be required to renounce your non-U.S. citizenship before a DOE L or Q clearance will be processed/granted.
Note: This listing has multiple openings; these are Career Indefinite positions. Lab employees and external candidates may be considered for these positions.
