We are seeking a Computer Scientist to join the Computational Simulation group as a member of the Sierra Thermal Fluids team or the Sierra Toolkit team. The Sierra Thermal Fluids team creates, improves, and productionizes computational simulation tools used by Sandia's thermal and fluids analyst community to answer questions and solve problems of tremendous importance to our national security. The Sierra Toolkit team develops the software underlying all of Sierra and preparing it for the next-generation of world-class supercomputers.
Our broader Computational Simulation Group at Sandia, is a team of researchers developing state of the art computational mechanics capabilities and deploying them for broad impact throughout DOE and DoD. This includes developing a variety of simulation codes (solid mechanics, fluid flow, structural dynamics, topology optimization, thermal, mesh generation, coupled codes) as well as developing the expertise to use these codes in ways that provide confidence in the generated results (validation and verification techniques).
Our codes must run on the largest and most complex computers in the world, requiring expertise in computer science and its application. We operate in an integrated teaming environment as we produce the software, validate its correctness, and certify confidence of results. We are looking for strong candidates who can contribute, including researchers trained in computational thermal and fluid mechanics. We are also seeking researchers skilled in computer science, including advanced data structures for parallel machines, memory layout for hybrid next generation computer architectures, use of accelerators (e.g. GPUs), multi-threading or associated technologies.

Experience with high performance and parallel computation concepts (e.g. distributed and shared memory, multithreading, OpenMP, MPI\+X\+Y, GPUs, CUDA, Kokkos)
Experience with thermal analysis and fluid mechanics software development
Experience developing within large scale production scientific software applications for computational engineering
Depth and breadth in several aspects of computational mechanics (e.g., equations solvers, element formulations, multi-scale approaches, data structures, coupled physics)
Experience with numerical analysis and finite element analysis
Experience teaming with other software developers and users of software
Excellent communication skills as evidenced by a history of publication of results in peer-reviewed journals and external presentations at appropriate scientific conferences
Ability to excel within an agile/scrum/Kanban software development team room environment
The Computational Thermal and Fluid Mechanics Department develops aerodynamics, aerothermodynamics, compressible fluid mechanics, and flight dynamics simulation software to execute on a variety of high performance computing platforms. These codes will be used to perform highly detailed simulations for use in the design, development and qualification of nuclear weapons. The code development efforts are focused on providing tools for analysts at Sandia and partner institutions. The code areas are primarily in thermal analysis and compressible flow (subsonic, transonic and hypersonic), and shock physics. Our broader code development team also develops simulation capabilities for modeling shock physics, solid mechanics, structural dynamics, participating media radiation, fire environments, and incompressible fluid flow (with capillary hydrodynamics, drying, porous flow -- multi-physics). Code teams are typically five to ten people, and strong interaction with the analysis teams is an important part of the code development process.

Position requires a Department of Energy (DOE) Q-level security clearance.
Sandia is required by DOE to conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Applicants for employment must be able to obtain and maintain a DOE Q-level security clearance, which requires U.S. citizenship. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted.
Applicants offered employment with Sandia are subject to a federal background investigation to meet the requirements for access to classified information or matter if the duties of the position require a DOE security clearance. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause a clearance to be denied or terminated by DOE, resulting in the inability to perform the duties assigned and subsequent termination of employment.
All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or veteran status.
