Code Developer - Computational Solid Mechanics

Lawrence Livermore National Laboratory
Livermore, CA 94550

We have multiple openings for Code Developers. You will create or adapt state-of-the-art computational mechanics algorithms, ensure the fidelity and performance of their implementation, and support their usage by multiple teams on demanding classes of problems. These positions are in the Computational Engineering Division (CED), within the Engineering Directorate. CED provides support to Weapons and Complex Integration (WCI) Programs.

In this role you will

  • Create or identify state-of-the-art computational mechanics algorithms that extend modeling capabilities, implement as software suitable for high-performance computers, and document their verification.
  • Establish expertise in using one or more finite-element based simulation tools such as ParaDyn or Diablo.
  • Evaluate algorithms for current and future problem classes, developing a body of experience with which to guide users and establish strategies for future improvements.
  • Proactively interact with users to assess software performance and provide solutions for moderately complex issues of modeling or software errors.
  • Adapt software development and QA practices and contribute to their continuous improvement.
  • Document efforts in technical reports, publish papers in peer-reviewed journals, and present results at scientific meetings and conferences.
  • Contribute to technical practices and mechanical and structural systems with internal and external collaborators.
  • Perform other duties as assigned.

  • Ph.D. in engineering or computational mechanics required, preferably with an emphasis in solids
  • Comprehensive knowledge of computational mechanics, in particular the theory and application of finite element methods for nonlinear solid and structural mechanics and/or the mechanics of materials
  • Proficiency in C/C++ or Fortran programming.
  • Comprehensive knowledge in at least one of the following topical areas: advanced spatial discretization for large deformation response, advanced representations of nonlinear response for metals or other material classes, coupled multi-physics simulation, including thermal-structural and/or fluid-structural interaction.
  • Experience conducing independent research.
  • Proficient verbal and written communication skills necessary to effectively collaborate in a team environment and present and explain technical information.
  • Ability to travel.

Qualifications We Desire

  • Familiarity with computational mechanics methods especially the finite element method
  • Experience with software implementations on parallel systems and heterogenous architectures
  • Knowledge of constitutive model development for traditional and non-traditional solids
  • Proficiency in Fortran

Pre-Employment Drug Test: External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test.

Anticipated Clearance Level: Q (Position will be cleared to this level). Applicants selected will be subject to a Federal background investigation and must meet eligibility requirements for access to classified information or matter. In addition, all L or Q cleared employees are subject to random drug testing. If you hold multiple citizenships (U.S. and another country), you may be required to renounce your non-U.S. citizenship before a DOE L or Q clearance will be processed/granted.
