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 will be in the Weapon Analysis and Methods (WAM) section within the Computational Engineering Division (CED) of the Engineering Directorate.

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 the development of finite element analysis (FEA) models of mechanical components and contribute to the integration of the components into structural models at system level
• Perform structural and/or thermal analyses using in-house codes for design, modification, optimization, testing, and certification of the nuclear weapon systems, in general technical guidance
• Document and present (as appropriate) simulation and analysis results and technical approaches
• Work with teams of analysts, code developers, engineers, and subject matter experts using established workflows, standards, and verification/validation best practices to solve technical problems under general direction
• Support deliverables with occasional travel as needed
• Perform other duties as assigned

• Develop finite element analysis (FEA) models of nuclear weapon systems, perform rigorous FEA of the systems, make engineering judgments on the system performances, and provide engineering resolutions to technical issues under limited direction
• Work independently and with teams using established workflows, standards, and verification/validation best practices to solve moderately complex technical problems under limited direction
• Participate in formal and informal design reviews as required
• Develop engineering analysis capability enhancements to achieve project deliverables, which may include contributing to FEA codes and pre-/post-processing systems

• Ability to secure and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship
• Masters degree in mechanical, structural, or aerospace engineering, or…
