This is the lowest to highest salary we in good faith believe we would pay for this role at the time of this posting; pay will not be below any applicable local minimum wage. An employee’s position within the salary range will be based on several factors including, but not limited to, specific competencies, relevant education, qualifications, certifications, experience, skills, seniority, geographic location, performance, and business or organizational needs.

We have multiple openings for Mechanical/Structural Engineering Analysts with a strong background in solid mechanics and finite element analysis (FEA) to support Lawrence Livermore National Laboratory (LLNL) stockpile programs. In this role, you will perform computational modeling and simulation using advanced, nonlinear finite element analysis codes developed at LLNL to evaluate structural and material responses to combined thermal, quasi-static or dynamic, and hydrodynamic loads under time-dependent kinematic conditions.

You will contribute to research and development in advanced simulation capabilities, including constitutive modeling, Simulation Process and Data Management (SPDM), as well as Verification, Validation, and Uncertainty Quantification. Your work will support engineering design, testing, and certification of the nation’s nuclear weapon systems through both advanced development and practical design and assessment initiatives. These positions are in the Weapon Analysis and Methods (WAM) section within the Computational Engineering Division (CED) of the Engineering Directorate.

This position 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:

• Contribute to and actively participate in the conception, development, implementation, execution, and documentation of FEA models of structural systems and their mechanical components, with emphasis on state-of-the-art computational techniques and constitutive modeling to evaluate the responses of structures and materials subjected to thermal, time-dependent displacement, and structural loads.
• Perform engineering analysis with limited guidance using FEA models and other solution methods to support stakeholders in design, modification, optimization, testing, and certification of nuclear weapon systems.
• Thoroughly document solution approaches, activities, sequences, requirements, and implementation practices including corresponding engineering assumptions, and present and explain analysis results to the team, as well as internal and external stakeholders.
• Collaborate and communicate with multi-disciplinary teams of engineering analysts, code developers, design engineers, and subject matter experts using established workflows, standards, and verification/validation best practices to solve moderately complex technical problems with limited direction within the scope of the assignment.
• Participate in and contribute to design reviews, training, briefings, or other program-related events, including describing analyses, input assumptions, potential enhancements, and current limitations during meetings with sponsors, other DOE Laboratories, and U.S. government agencies, which will require…
