Computational Physics Scientist (Scientist 2)

Updated: 4 months ago
Location: Los Alamos, NEW MEXICO
Job Title Computational Physics Scientist (Scientist 2)
Location Los Alamos, NM, US
Organization Name XCP-2/EULERIAN CODES

What You Will Do

The Eulerian Codes Group (XCP-2) in X-Computational Physics Division is seeking multiple career scientists in pursuit of a research and development position focused on numerical algorithmic integration of high-fidelity physics models into large-scale, Eulerian, multi-physics simulation codes.  XCP-2 offers an exciting, flexible, scientifically challenging work environment, including the opportunity to develop code in a cutting-edge, state-of-the-art, massively parallel computing environment, as well as collaboration opportunities with LANL experimentalist, and model developers.

XCP-2 maintains the Eulerian AMR numerical simulation tools for Los Alamos National Laboratory’s national security design community, the Inertial Confinement Fusion High Energy Density Physics user community as well as University collaborators researching astrophysical phenomena.  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 computing platforms. Our projects bring together a diverse community of computer and physical scientific expertise to develop multi-physics models for advanced predictive software capabilities. We serve as the interface to judiciously integrate into LANL’s Eulerian simulation tools, results produced from coordinated efforts between experimentalists and physical model developers. XCP-2 ensures that state-of-the-art Eulerian numerical techniques are robustly integrated; executing code development, testing, and support, 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 will be 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.

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.
