Job Description

We have an opening for a Computational Mechanics Code Developer. 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. This position is in the Computational Engineering Division (CED), within the Engineering Directorate. CED provides support to Strategic Deterrence (SD) Programs.

This position will be filled at either level based on knowledge and related experience as assessed by the responsibilities (outlined below) will be assigned if hired at the higher level.

In this role you will

  • Create or identify state-of-the-art computational mechanics algorithms that extend modeling capabilities, implement 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, Diablo, or ALE3D.
  • 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.

Additional job responsibilities, at the SES.3 level

  • Lead teams in the development, implementation, and application of new methods in one or more of the following areas:
    • Problems of interest in manufacturing.
    • Methods which employ multi-scale and multi-simulation models which may include Machine Learning/AI.
    • Methods which leverage emerging compute hardware (e.g. GPUs) and related computer science programming paradigms to enable highly efficient and scalable simulations.

Qualifications

  • Ability to secure and maintain a U.S. DOE Q-level security clearance which requires U.S. Citizenship.
  • PhD in Engineering or Computational Mechanics, preferably with an emphasis in solid mechanics, or an equivalent combination of education and experience.
  • Proficiency in C/C++ or Fortran programming.
  • Significant 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, additive manufacturing, numerical methods for fracture.
  • Experience conducting 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.

Additional qualifications at the SES.3 level

  • Significant experience in academic, industrial, or national-laboratory settings with a lead role in the development of computational mechanics algorithms and applications.
  • Comprehensive knowledge of computational mechanics, in particular the theory and application of finite element methods for nonlinear mechanics problems including but not limited to solid mechanics and heat transfer.

Qualifications We Desire

  • Familiarity with finite element methods as applied to computational mechanics.
  • Experience with software implementations on parallel systems and heterogenous architectures.
  • Knowledge of constitutive model development for traditional and non-traditional solids.
  • Familiarity with machine learning/ deep learning programming frameworks (PyTorch, tensor flow, etc.). Proficiency in Fortran.
  • Familiarity with some commercial codes such as flow3d, Ansys, Abaqus, especially with regards to Additive Manufacturing simulations.
