About The Position

Lawrence Livermore National Laboratory (LLNL) is seeking Mechanical Engineers to participate in new and ongoing projects within the Defense Technologies Engineering Division (DTED) of the Engineering Directorate. These roles involve providing nuclear weapon engineering design expertise, systems engineering, experimental device design, shock & vibration and thermal testing, fabrication and assembly, and assessment of nuclear stockpile components for evaluation and maintenance of the enduring and future nuclear weapon stockpile. You will collaborate with colleagues at other National Laboratories, Production Agencies, National Nuclear Security Administration (NNSA), and Department of Defense (DoD). These positions support Strategic Deterrence (SD) Programs and may offer a hybrid schedule, blending in-person and virtual presence with flexibility to work from home. Multiple openings are available, and positions will be filled at either the SES.1 or SES.2 level based on knowledge and related experience, with additional responsibilities assigned at the higher level.

Experience working in an environment with stringent safety and security policies.

Responsibilities

Derive engineering requirements, develop conceptual designs, and perform supporting assessment of mechanical systems, test prototypes, and associated diagnostics.
Assist and support the detail design process, component part fabrication, and unit assembly.
Prepare supporting safety and engineering documentation and participate in engineering design reviews.
Participate in engineering testing operations, analyze results, and write reports.
Generate detailed plans, schedules, and budgets for project activities.
Interface with other organizations internal and external to the Laboratory to complete various projects.
Work independently as well as a part of a multidisciplinary team.
Perform other duties as assigned.
Provide comprehensive engineering knowledge to resolve technical and programmatic issues, using the broad application of technical concepts and techniques (at SES.2 level).
Perform independent technical tasks to provide solutions for a diverse range of moderate to complex issues that require the creative use of established or innovative methods (at SES.2 level).
Select methods, techniques, and evaluation criteria to obtain results based on analysis of multiple, largely identifiable factors (at SES.2 level).
May represent the organization by providing input on technical issues for specific projects (at SES.2 level).
May provide guidance and/or informal mentoring to less-experienced team members (at SES.2 level).
