  • Experience with modern C++ programming within a UNIX/Linux environment
  • Experience with computer software engineering concepts
  • Experience with software quality and testing practices
  • Experience with high performance and parallel computation concepts (e.g. distributed and shared memory, multithreading, OpenMP, MPI+X+Y, CUDA)
  • Excellent communication skills as evidenced by a history of publication of results in peer-reviewed journals and external presentations at appropriate scientific conferences
  • Experience teaming with other software teams and users of software
  • Ability to obtain and maintain a DoE Q clearance


  • Experience developing within large scale software applications
  • Experience with high-performance parallel computing, MPI, threads, GPUs (Kokkos would be great), and agile software development experience
  • Willingness to learn agile development practices such as test driven development and pair programming
  • Depth and breadth in several aspects of computational mechanics (e.g., equations solvers, element formulations
  • Multi-scale approaches, data structures, coupled physics)
  • Strong background in applied mathematics, physics, computer science and software development
  • Ability to excel within an agile software development team room environment
  • Experience with Kokkos

Department Description:

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.

Security Clearance:

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.

EEO Statement:

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.
