Los Alamos National Laboratory Computational Physics Scientist (Scientist 2) in Los Alamos, New Mexico

What You Will Do

The Eulerian Codes Group (XCP-2) in X-Computational Physics Division is seeking a career scientist in pursuit of a research and development position focused on integration of high-fidelity physics models into large-scale, Eulerian, multi-physics simulation codes. XCP-2 offers an exciting, flexible, scientifically challenging work environment, with freedom to publish. We provide the opportunity to develop code in a state-of-the-art massively parallel computing environment, as well as collaboration opportunities with LANL experimentalist and model developers. The successful candidate will spend approximately half time on code development, and the other half-running simulations on applications the Safety Applications Project supports.

XCP-2, in collaboration with the Safety Applications Project (SAP), helps to maintain the Eulerian numerical simulation tools for Los Alamos National Laboratory’s safety and security community and global security mission. In this role, XCP-2 develops intricate computational simulation tools to model highly coupled nonlinear multi-physics problems within an Eulerian framework; exercised on massively parallel state-of-the-art DOE platforms. Our tools are Eulerian hydrodynamics codes that operate on fixed, logically structured meshes, e.g. the Pagosa code. In addition, the SAP is responsible for the measured introduction and support of other codes for use in the safety and global security missions. Our user community also includes students and university collaborators researching shock physics phenomena and material properties experiments. XCP-2 ensures that Eulerian numerical techniques are robustly integrated, comprehensively tested, and well supported, within an environment adhering to Software Quality Assurance (SQA) guidelines. In support of the national-security programs and mission of the Laboratory, the successful applicant is expected to publish results in peer-reviewed journals and present at both classified and unclassified professional conferences. Applicants in all career stages will be considered.

Technical areas of interest for this position include:

  • Code development for massively parallel computing (e.g. develop inline material description initialization, inline visualization, automatic material prioritization for Eulerian simulations).

  • Compressible Eulerian hydrodynamics (algorithmic development and implementation methods).

  • Material modeling (i.e. strength, damage, porosity growth, etc.) in and Eulerian algorithmic framework.

  • High Explosives modeling and algorithmic development (e.g. Scaled Unified Reactive Front+, Wescott-Stewart-Davis Tarver-Lee, linked Detonation Shock Dynamics).

  • Use of equations of state/constitutive models in Eulerian Hydrocodes.

  • Shock-wave physics.

  • Code project infrastructure (e.g. automated build/test on multiple, diverse platforms).

The successful candidate will be required to do the following:

  • Production of high-quality scientific computer code (e.g., Fortran, C/C++): Implementation of physical models into simulation codes, following best SQA practices including documentation, and peer-reviewed design planning, implementation, and testing; adhering to institutionally accepted software quality standards.

  • Publication and presentation of personal technical work: Publish technical work in peer reviewed scientific journals and deliver presentations (e.g., talks, posters) at professional conferences.

  • Citizenship: Serve in role as XCP-2 technical point of contact for planning and organization of professional meetings and collaborations with other DOE labs.

  • Mentoring: Technical mentoring and leadership, providing guidance and direction to XCP-2 graduate students.

What You Need

Minimum Job Requirements:

  • Proficiency in one of the following: Fortran, C, C++, and/or Python.

  • A track record of high-quality scientific publications and presentations at national/international meetings (commensurate with years of experience).
