Join us and make YOUR mark on the World!

Lawrence Livermore National Laboratory (LLNL) has turned bold ideas into world-changing impact advancing science and technology to strengthen U.S. security and promote global stability.

Our mission spans four critical national security areas nuclear deterrence, threat preparedness, energy security, and multi-domain defense empowering teams to take on the toughest challenges of today and tomorrow. With a culture built on innovation and operational excellence, LLNL is a place where your expertise can make a real impact.

We have multiple openings for
Product Design Engineers to support component design or surveillance efforts. Responsibilities could be focused on weapon component product designs and/or weapon surveillance process development, design verification (testing and/or analysis, including assessment of collected surveillance data) and release of product definition (drawings and specifications) to production agencies. You will also support resolution of production-partner related issues, develop/execute engineering evaluations of production and surveillance processes at the production facilities and evaluate non-conformances.

You will be assigned to one or more Product Realization Teams (PRTs) supporting nuclear weapon modernization programs or enduring systems. These positions are in the Defense Technologies Engineering Division (DTED), within the Engineering Directorate. DTED provides support to Strategic Deterrence (SD) Programs.

These positions 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.

These positions 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.

You will

• Coordinate, administer, update, and release PRT documentation including project plans, qualification plans, design requirement documentations, and interface definitions, following standard techniques and methodologies.
• Contribute to and derive engineering requirements, develop conceptual designs, perform supporting assessment of mechanical components, systems, test prototypes and associated diagnostics, and support realization of production and/or surveillance processes at Production Agencies, using defined practices, principles, and concepts.
• Contribute to and/or prepare supporting safety and engineering documentation.
• Participate in engineering test operations, provide engineering support, and collaborate with team members in analyzing results, and writing technical reports.
• Review and support producibility, manufacturability and/or surveillance process issues, and provide solutions to operational problems of limited complexity.
• Participate in formal and informal engineering design reviews, multi-site PRT meetings, and program reviews.
• Perform other duties as assigned.

Additional job responsibilities, at the SES.
2 level

• Utilize comprehensive engineering knowledge and apply relevant experience and broad technical concepts and techniques to resolve complex technical and programmatic issues.
• Exercise independent judgment to determine methods, techniques, and evaluations criteria to obtain and analyze results, and to provide solutions for a diverse range of moderately complex problems that require the creative use of established or innovative methods and often involve multiple, largely identifiable factors.
• Coordinate and contribute to the execution of engineering testing and data analysis and assist in preparing technical reports, documentation, and presentations.
• Contribute to the successful completion of project and organizational goals and provide input on technical issues for specific tasks and projects.
• May provide guidance and/or informal mentoring to less experienced team members.
