Job Description

We have an opening for a Mechanical Engineer.  You will work on projects and operations supporting diagnostics and experiments for our two-stage gas gun at the Joint Actinide Shock Physics Experimental Research (JASPER) facility. You will work on the design, implementation, integration, fielding, and operation of new diagnostics and new experiments used in the study of materials under extremely high pressures and temperatures. You will provide engineering solutions for a variety of projects ranging from upgrades to the current systems to development of the next generation systems. You will be involved throughout the product development life cycle, starting with concept initiation and requirements gathering to implementing the design details. Our engineers interface with colleagues at other National Laboratories, the National Nuclear Security Administration (NNSA) and other NNSA contractors. This position in the National Security Engineering Division (NSED), within the Engineering Directorate.

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. 

In this role you will 

  • Oversee and participate in the operation of a gun facility, execution of physics experiments, development projects, and integration of systems.
  • Develop engineering requirements, conceptual designs, and perform supporting analyses of electro-opto-mechanical diagnostic systems and targets, test prototypes for the current and next generation diagnostic systems, safety engineering documentation, deployment of production systems.
  • Provide advanced conceptual solutions to a diverse range of moderate to complex issues/problems that require analysis and creative use of established techniques and methods.
  • Collaborate with team members to ensure the successful integration and proper functioning of integrated systems.
