Company Description

Join us and make YOUR mark on the World!

Are you interested in joining some of the brightest talent in the world to strengthen the United States’ security? Come join Lawrence Livermore National Laboratory (LLNL) where our employees apply their expertise to create solutions for BIG ideas that make our world a better place.

We are looking for individuals that demonstrate an understanding of working in partnership with team peers, who engage, advocate, and contribute to building an inclusive culture, and provide expertise to solve challenging problems.

Job Description

We have multiple openings for Computational Engineers to conduct basic and applied research in the optimization, simulation, and design of physical and engineered systems. You will work collaboratively and independently to extend and develop physics-based design optimization tools. The team is working to both extend the state-of-the-art and support Laboratory missions. These positions are in the Computational Engineering Division (CED) of the Engineering Directorate.

These positions will be filled at either level based on knowledge and related experience as assessed by the hiring team. Additional job responsibilities (outlined below) will be assigned if hired at the higher level.

In this role you will

  • Develop and implement HPC algorithms and simulations for the optimal design of engineering systems governed by nonlinear, transient, multiscale, and multiple physical phenomena that include uncertainties in geometry and material properties.
  • Contribute to solving challenging design optimization problems.
  • Develop forward model, continuum simulations to solve the governing partial differential equations of physical systems necessary for advanced design.
  • Document research through presentations and peer-reviewed journal articles and contribute to identifying future research directions and proposals that will provide opportunities in the field.
  • Perform other duties as assigned.

Additional job responsibilities, at the SES.3 level

  • Guide the establishment of future research directions and influence proposals that will provide future research opportunities in the field.
  • Identify and solve challenging design optimization problems highlighting capabilities and establishing credibility with mission customers.

Qualifications

  • Ph.D. in Engineering, Mathematics, Computational Science, or a related field, or the equivalent combination of education and related experience.
  • Knowledge of shape/topology optimization techniques and algorithms.
  • Experience developing simulation tools using continuum approaches (e.g., finite elements) for physical systems.
  • Experience programming skill in C/C++/FORTRAN and scripting languages including Python/Matlab.
  • Comprehensive experience with explicit design sensitivity analysis via direct (forward) and adjoint (backward) methods.
  • Knowledge of massively-parallel computing and one or more associated parallel programming interfaces, such as MPI, OpenMP, or CUDA.
  • Proficient verbal and written communication skills needed to effectively collaborate in a team environment, present and explain technical information, document work, prepare and present successful proposals and high-quality research papers.

Additional qualifications at the SES.3 level

  • Advanced knowledge of shape/topology optimization techniques and algorithms.
  • Significant experience developing simulations tools using continuum approaches (e.g., finite elements) for physical systems and advanced programming skill in C/C++/FORTRAN and scripting languages including Python/Matlab.
  • Significant experience with explicit design sensitivity analysis via direct (forward) and adjoint (backward) methods and experience with massively-parallel computing and one or more associated parallel programming interfaces, such as MPI, OpenMP, or CUDA.
  • Advanced verbal and written communication skills needed to effectively collaborate in a team environment, present and explain technical information, document work, prepare and present successful proposals and high-quality research papers.

Qualifications We Desire

  • Exposure to machine learning and other data science techniques.

Security Clearance

LLNL is a Department of Energy (DOE) and National Nuclear Security Administration (NNSA) Laboratory.  Most positions will require a DOE L or Q clearance (please reference Security Clearance requirement).  If you are selected, we will initiate a Federal background investigation to determine if you meet eligibility requirements for access to classified information or matter. In addition, all L or Q cleared employees are subject to random drug testing.  An L or Q clearance requires U.S. citizenship.  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.  For additional information please see DOE Order 472.2.

Equal Employment Opportunity

LLNL is an affirmative action and equal opportunity employer that values and hires a diverse workforce. All qualified applicants will receive consideration for employment without regard to race, color, religion, marital status, national origin, ancestry, sex, sexual orientation, gender identity, disability, medical condition, pregnancy, protected veteran status, age, citizenship, or any other characteristic protected by applicable laws.
