About The Position

Defense Technologies Engineering Division (DTED) has multiple openings for Mechanical Test Engineers to support the Environmental & Mechanical Test Group. Under supervision, you will conduct experimental testing on a variety of projects related to environmental testing, modal analysis, health monitoring, aging studies, data acquisition, load testing, general instrumentation and measurement diagnostics. Work supports multiple program areas, including Strategic Deterrence, Global Security, and the National Ignition Facility. This position will report to a DTED Environmental & Mechanical Test Group Leader. Depending on your assignment, this position may offer a hybrid schedule, blending in-person and virtual presence. You may have the flexibility to work from home one or more days per week. This position will be filled at either level based on knowledge and related experience as assessed by the hiring team. Additional job responsibilities (outlined below) will be assigned if hired at the higher level.

Requirements

Ability to obtain and maintain a U.S. DOE Q-level security clearance which requires U.S. Citizenship.
Bachelor’s degree in Mechanical Engineering or equivalent Combination of education and experience.
Fundamental knowledge of testing practices and data processing.
Fundamental 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.).
Experience using MatLab or other computer programming codes for data manipulation and analysis.
Fundamental knowledge of engineering hardware design and fabrication.
Effective communication skills with proven ability to present technical concepts and ideas in a clear and coherent manner, both verbal and written for presentation and collaboration with other technical staff members.

Nice To Haves

Master’s (MS) or PhD in Mechanical Engineering
Comprehensive knowledge of measurement sensors and an understanding of when to use specific sensors for certain applications
Ability to use independent judgment in determining methods, techniques, and evaluation criteria.
Comprehensive verbal and written communication skills necessary to effectively collaborate in a team environment and present and explain technical information.

Responsibilities

Design and conduct tests on mechanical and/or diagnostic systems, analyze results, and author reports.
Conduct experimental modal analyses and analyze results in concert with modeling and simulation.
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 detailed 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.
Work as a member of a project team in a dynamic environment.
Interface with peers both internal and external to the organization to plan and execute testing.
Perform other duties as assigned.
Independently define engineering requirements for structural, thermal, fluidic, and diagnostic systems within assigned project scope.
Generate detailed plans, schedules, and budgets for project activities.
Perform independent technical tasks and projects and support research efforts and select methods, techniques, and evaluation criteria for obtaining results based on analysis of multiple, largely identifiable factors.
