HEAF HE Test Engineer

Science and Technology on a Mission!

For more than 60 years, the Lawrence Livermore National Laboratory (LLNL) has applied science and technology to make the world a safer place.

We have an opening for a Mechanical Engineer to participate in new and ongoing projects related to the mechanical properties testing of high explosives (HE). We provide nuclear weapon engineering design expertise; systems engineering; experimental device design; fabrication and assembly; surveillance of nuclear stockpile components; engineering analysis and computational simulation; and engineering testing for evaluation and maintenance of the enduring and future nuclear weapon stockpile. Our engineers interface with colleagues at other National Laboratories and Production Agencies, National Nuclear Security Administration (NNSA), and Department of Defense (DoD), and their contractors. This position is in the Defense Technologies Engineering Division (DTED), within the Engineering Directorate. DTED provides support to Weapons and Complex Integration (WCI) Programs.

This position will be filled at either the SES.1 or SES.2 level depending on your qualifications. Additional job responsibilities (outlined below) will be assigned if you are selected at the higher level.

Essential Duties
- Provide oversight of technical associates supporting mechanical properties testing and responsible for daily test schedule.
- Responsible for data storage and optimize distribution to customers.
- Interface with technical and programmatic leadership to ensure mission deliverables are completed.

- Prepare supporting safety and engineering documentation and participate in engineering design reviews, as well as serve as the responsible individual for the Work Control Document. 
- Participate in manufacturing requests and inventory management of inert and explosive components.
- Oversee hardware development to enable the performance of novel or improved tests.
- Participate in engineering testing operations, analyze results, and write reports, as well as generate detailed plans, schedules, and budgets for project activities.
- Interface with other organizations internal and external to the Laboratory to complete various projects and work independently as part of a multidisciplinary team.
- Perform other duties as assigned.

In Addition at the SES.2 Level
- Provide engineering solutions for moderately complex technical and programmatic issues and perform independent technical tasks to provide solutions for a diverse range of moderate to complex issues. 
- Select methods, techniques, and evaluation criteria to obtain results based on analysis of multiple, largely identifiable factors.

- Automate data processing and data acquisition using common engineering software tools and design tests to elucidate specific material behaviors or failure mechanisms, with input from Analysis group. 

- Bachelor's degree in Mechanical Engineering or related field, or the equivalent combination of education and related experience.
- Knowledge of two or more of the following: engineering hardware design, systems engineering, manufacturing techniques, testing processes, FEA structural analysis.
- Familiar with Matlab data processing and LabVIEW data acquisition.
- Working knowledge of and/or experience with design principles and complex material properties testing.
- Experience using standard project management practices and working effectively in a multidisciplinary team environment.

- Ability to become an Explosives Handler and the ability to train others and provide technical direction to team members
- Desire to work on National Security projects related to nuclear weapons and flexibility to work in different technical areas.
- Sufficient verbal and written communication skills to collaborate effectively in a team environment and present and explain technical information.

In addition at the SES.2 Level
- Master's degree in Mechanical Engineering or related field, or the equivalent combination of education and related experience.
- Comprehensive knowledge of engineering hardware design, fabrication, or testing processes and ability to meet schedule and deliverables for multiple concurrent projects with a range of priorities.
- Proficient verbal and written communication skills necessary to effectively collaborate in a team environment and present and explain technical information.

Desired Qualifications
- Ability to interpret specifications and mechanical drawings including Geometric Dimensioning & Tolerancing (GD&T). Knowledge of design applications employing high explosive materials and working knowledge of explosives surveillance program and the associated testing protocols.

- Experience with digital image correlation for strain measurements. Familiar with common data acquisition hardware and techniques and thermal expansion measurement techniques.
- Experience working in an environment with stringent safety and security policies.

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 an active Department of Energy (DOE) Q-level clearance or active Top Secret clearance issued by another U.S. government agency at time of hire. 


Note:   This is a Career Indefinite position. Lab employees and external candidates may be considered for this position.
