Mechanical Engineer - Computational Solid Mechanics

Responsibilities

• Apply principles of solid mechanics and advanced computational finite-element methods to provide engineering solutions.
• Conduct predictions of complex, nonlinear material behavior from deformation to failure in multi-physics environments.
• Perform full-system scale finite element modeling of transient dynamic events such as crash, crush, and impact.
• Collaborate with computational and experimental mechanics specialists to drive technical innovation.
• Partner with multi-physics code development teams to enhance robust predictive capabilities.
• Work with internal customers to discuss simulation results and negotiate project deliverables.

Requirements

• Bachelor's degree in a relevant discipline (Mechanical, Civil, Aerospace, or related field) or equivalent relevant experience.
• Ability to obtain and maintain a DOE Q security clearance.
• Fundamental knowledge of finite element analysis (FEA), including element selection, contact, and material/constitutive model selection.
• Experience with nonlinear computational mechanics, including large to extreme deformation solid mechanics.
• Experience with high-performance scientific computing and scripting using Python, MATLAB, or similar languages.

Preferred Qualifications

• Graduate degree in Mechanical Engineering or a highly related field involving independent research.
• Experience with Sierra Solid Mechanics or other commercial large-scale finite element software.
• Experience with multi-physics computational mechanics (e.g., thermal, mechanical, shock).
• Experience in independent research and proposal development.
• Previous experience with mechanical engineering and product realization in the NNSA complex.

Benefits
