Job Description:

What You Will DoAre you interested in a career in computational physics? If the answer is "yes" we invite you to learn more about our opening for a Senior Scientific Software Engineer. In this role you would lead projects related to neutral particle transport, equations of state, solid mechanics, high explosives modeling, compressible hydrodynamics, or shock physics. In addition, there will be opportunities to work on performance optimization and porting algorithms to heterogeneous computing architectures.Technical Areas of Interest:Performance optimization and porting of existing algorithms to heterogenous computing architectures using Kokkos, CUDA, HIP, OpenMP, or RAJAExploration and documentation of possible performance benefits via new algorithms or implementations of physics of interest to the Eulerian Codes groupProfiling and optimization of scientific softwareLarge-scale code designBuild systems, package managers, CI/CD, and containersThe Eulerian Codes Group (XCP-2) develops and maintains large scale, massively parallel multi-physics codes as part of the Advanced Scientific Computing (ASC) Program. The Eulerian Codes Group's staff span a wide range of computational physics modeling disciplines including the following: numerical fluid and solid mechanics, materials science, radiation hydrodynamics, plasma physics, turbulence, magnetohydrodynamics, high explosives, nuclear physics and engineering, and neutral and charged particle transport. Other XCP-2 research efforts focus on the development and optimization of cutting-edge physics algorithms for performance on both homogeneous and heterogeneous high-performance computing platforms. The duties of our well-compensated professionals include research and development of applied physics and engineering models, the implementation of these methods into production codes using excellent software development practices, the testing and validation of these methods, and the education and support of users as they adopt these methods. We facilitate mentoring for new staff to build skills quickly, and we work within a dynamic multi-physics team environment that facilitates productive and collaborative relationships with our software users, other software teams, and with theoreticians and experimentalists across LANL.What You NeedMinimum Job Requirements:Technical KnowledgeFor this role you must have demonstrated thorough professional knowledge, experience, and leadership in computational modeling of one or more of the technical areas of interest listed above.Software Engineering & DesignYou will need to have recognized proficiency with modern Fortran, C, or C++ and/or experience in the development of multi-physics scientific codes, including software engineering practices and user support.CollaborationTeamwork is essential to the success of our group.
