Longenecker & Associates (L&A), a Geosyntec Company, is a trusted partner enabling critical missions across the U.S. Department of Energy (DOE) complex for more than 30 years. We contribute to DOE’s nuclear security and environmental remediation enterprise by providing the highest-caliber staff and experts. We are seeking a motivated Research and Development Engineerto contribute to our mission supporting our work atSandia National Labs in Livermore, California.

Essential Duties and Responsibilities

The Telemetry (TM) team at the National Laboratories in Livermore, CA is seeking an R&D Mechanical Engineer to join our dynamic team! We are responsible for the design, development, testing, and qualification of multiple telemetry products across the ND portfolio. As a Mechanical Engineer, you will contribute to the mechanical design, conduct full product environmental testing, and verify requirements in support of qualification and product delivery. Your role will also include fixture development, documentation, hardware assembly, and managing fabrication processes. Our telemetry units are highly integrated electro-mechanical designs that must operate effectively in severe environments. Success in this role requires the ability to collaborate with a multi-faceted engineering team.

Organization 8434, Telemetry Engineering II - along with sister departments 08432, 08433, 08435 and 08436- has responsibility for the design, development, and qualification of weapon system instrumentation (or telemetry systems) for use in Joint Test Assemblies (JTAs) for the entire US nuclear arsenal. The JTA program is a cornerstone of the Stockpile Evaluation Program and allows critical assessment of the weapon system, DoD platform, and support personnel performance. To fulfill its mission responsibilities, Organization 8434 employs a diverse and talented group of electrical engineers, mechanical engineers, and technologists. The Organization collaborates with other NW groups within the National Laboratories and across the Nuclear Weapons Complex, including NNSA, Lawrence Livermore National Laboratory, Los Alamos National Laboratory, the production agencies (National Security Center and Pantex), and the DoD. Organization 0843x is also expected to have significant interactions with other DOE Laboratories and other NNSA entities (beyond the NW Complex), the DoD, and other government agencies.
