Computational Structural Mechanics (CSM) Scientist

Clearance Level
Vicksburg, Mississippi

REQ#: G2019-61643

Public Trust: None
Requisition Type: Regular


At GDIT people are our differentiator. As an HPC (High Performance Computing) Computational Scientist / Engineer you will be trusted to support our HPC PET program with locations across the USA.

The Department of Defense (DoD) High Performance Computing Modernization Program (HPCMP) Productivity Enhancement and Training (PET) initiative. PET enhances the capability and productivity of the HPCMP community through training, collaboration, tool and software development, technology transfer, and outreach.

We currently have a position in Vicksburg, MS for a Computational Scientist

You will join teams of computational experts representing a critical mass of expertise in key areas of support for the HPCMP and your focus will be CSM.  CSM codes are frequently coupled with CFD or CCM codes in multidisciplinary applications. For the DoD, CSM predicts material and structural response of armor, aircraft, ships, and force protection (buildings and structures).

Duties may include the following;

  • Work with HPCMP users to identify needs and define requirements for air vehicle survivability; analysis of coupled thermal/structural/acoustic problems; numerical tools for multiscale modeling; V&V; integration of advanced material models; and computational support for blast/fragmentation/structure interaction
  • Provide application-level support for major CSM codes, including but not limited to ALE3D, ABAQUS, ANSYS, CTH, EPIC, LS-DYNA, Sierra Mechanics and PATRAN
  • Provide technical support to CSM customers/users for existing and emerging software in terms of usability, performance optimization, validation/verification and strong/weak scaling.
  • Foster and develop collaborative relationships with DoD and non-DoD communities
  • Software Refactoring to Optimize Performance for Emerging Architectures

Technical Skills should include the following:

  • Expertise in the use of various programming languages used in scientific high-performance computing (FORTRAN, C/C++, Perl, Python), scientific visualization software (e.g., EnSite), and mesh generation software (e.g. Pointwise, GRIDGEN) is also preferred.
  • Experience with Linux on large scale systems.
  • Extensive knowledge of HPC and parallel programming techniques (e.g. MPI, OpenMP), in multiple physical science domains.

Additional Requirements:

  • Education: MS
  • 3 years’ Experience with HPC science or engineering programs
  • Must be a US Citizen and be eligible for a DoD clearance
