Weapon Systems Engineering Division (W Division/W Program) provides systems engineering and program management to ensure the safety, reliability and security of our Nation's nuclear stockpile for the entire life cycle. W Division is responsible for leadership of activities in stockpile assessment, certification, and life extension projects.

The Advanced Engineering Analysis Group (W-13) strives to provide our customers with timely and accurate answers to complex engineering problems by creatively combining cutting-edge numerical tools. Our customers include the nuclear weapons program, the Department of Homeland Security, and the Department of Defense, among others. W-13 group expertise includes structural dynamics, radiation transport, thermodynamics, hydrodynamics, probabilistic methods, mechanics of materials, and numerical analysis.

We have an immediate need for an expert in constitutive model implementation for finite element codes. This would typically require a Master's or Ph.D. Degree (or equivalent degree and experience) in the area of computational solid mechanics.

This position will be responsible for the following: Working closely with analysts to determine constitutive model requirements, working closely with materials characterization testers to define necessary characterization tests, leading brainstorming sessions to determine best theoretical models, drafting formal constitutive model implementation plans, implementing appropriate incremental forms of theoretical constitutive models for use in both implicit and explicit finite element analyses, performing analyses of appropriate verification and validation problems and documenting the results, working closely with test engineers to design validation experiments, analyzing large datasets from simulations and experiments to draw conclusions, critically evaluating modeling assumptions and theory and determining their associated errors and uncertainties in the simulation regimes of interest, presenting and defending constitutive model applicability, uncertainties, and error estimates at formal model validation peer reviews, writing formal conference papers and technical reports that clearly and effectively communicate constitutive model theory, model implementation details, user guidelines, and model verification and validation evidence, working within ISO 9001 compliant engineering simulation quality management system.

Key Position Requirements

Strong knowledge of fundamental engineering principles and practices. Expertise in continuum mechanics, nonlinear finite element analysis, and computational inelasticity. Extensive experience in implementation of constitutive models for finite element analysis. Demonstrated ability to contribute to the research, design, testing, analysis, verification, and validation of engineering and technology solutions in support of R&D initiatives. Strong written, oral and interpersonal communication skills. Thorough knowledge and experience with ABAQUS, DYNA3D, or SIERRA finite element analysis software. Experience with scripting using Python, Matlab, or ABAQUS is also desired. The position will make use of verification and validation (V&V) methods. Experience with formal V&V methods, statistical analysis (including design of experiments and sensitivity studies), and probabilistic analysis is highly desired. This position will require the ability to obtain a DOE Q Clearance which normally requires US citizenship.

Desired Skills: General knowledge of weapons. Working experience in ISO 9001 compliant engineering simulation quality management system.
