- 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.

Desired Qualifications
- 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.
