Nonlinear Computational Analysis Engineer

Overview

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.

LLNL’s mission spans four critical national security areas: nuclear deterrence, threat preparedness, energy security, and multi‑domain defense. With a culture built on innovation and operational excellence, LLNL is a place where your expertise can make a real impact.

• Assess and contribute to the response of complex mechanical systems subject to high-rate loading, including laser‑matter interaction, blast and hypervelocity impact problems, as part of a multi‑disciplinary project team.
• Work under limited direction to effectively manage concurrent technical tasks in a multi‑disciplinary team environment, including the development of large, geometrically complex finite element models.
• Apply comprehensive technical knowledge to guide the successful completion of project goals, including the assessment of the post‑failure response of materials and structures subjected to high‑rate loadings.
• Perform verification analyses to check computational methods against analytical solutions and verify that methods converge properly, and participate in technical peer review processes to ensure analytical rigor and quality.
• Participate and collaborate in training, briefings, or other program‑related events, including contributing to meetings with sponsors, other DOE Laboratories, and U.S. government agencies, which will require occasional travel.
• Ensure appropriate security requirements are met for all levels of classified/unclassified information with limited direction.
• Perform other duties as assigned.

• Work independently to effectively manage concurrent technical tasks in a multi‑disciplinary team environment, where commitments and deadlines are critical to project success.
• Apply advanced technical knowledge and methodologies to guide the successful completion of project and organizational goals and serve as the primary technical contact on tasks and projects.
• Resolve technical objectives and criteria to satisfy project objectives and execute the appropriate technical approaches with minimal direction.
• Collaborate with technical area leaders, project leaders, and program management to represent technical capabilities and project results to internal management and external sponsors.

• Ability to secure and maintain a U.S. DOE Q‑level security clearance, which requires U.S. citizenship.
• Master’s degree in mechanical engineering, aerospace engineering, structural engineering, structural/applied mechanics or related field, or an equivalent combination of education and related experience.
• Comprehensive knowledge of computational structural mechanics, with experience in one or more of the following areas: material failure, high‑rate system dynamics (e.g., penetration mechanics, hydrodynamics, or shock physics), hypervelocity impact, explosive modeling, or laser‑matter interaction.
• Proficient verbal and written communication skills needed to present and explain technical information, document work, prepare and present high‑quality research papers, and provide technical summaries to project leadership.
• Experience using programming or scripting languages such as Python to facilitate technical analysis.
• Experience documenting research results in formal reports.
• Ability to work independently and as a member of a multidisciplinary team.
• Ability to travel.

• Advanced knowledge of computational structural mechanics and state‑of‑the‑art modeling and simulation techniques, with significant experience in one or more of the following areas: material damage and failure mechanisms, high‑rate system dynamics, hypervelocity impact, explosive modeling, or laser‑matter interaction.
• Advanced verbal and written communication skills needed to effectively collaborate in a team environment, guide the technical direction of projects, prepare and present successful proposals, and provide advice to management and sponsors.
• Significant experience using programming or…
