Job Information

Los Alamos National Laboratory Verification and Validation Postdoc in Los Alamos, New Mexico

Vacancy Name: IRC74306


Job Title Verification and Validation Postdoc

Location Los Alamos, NM, US

Organization Name XCP-8/Verification And Analysis

Minimum Salary

Maximum Salary

What You Will Do

The Computational Physics: Verification & Analysis group (XCP-8) at the Los Alamos National Laboratory (LANL) has an opening for doctoral-level career scientists/engineers with research interests and experience in the areas of code and solution verification, and model validation. Our wide-ranging areas of interest include hydrodynamics, solid mechanics, material strength and damage, equation of state, reactive flow, high-energy-density physics, instabilities and turbulence, and radiation transport. We encourage mentoring for new staff to build skills quickly and continued publications/research are prized as well. This position is ideal for those who have completed post-doctoral work.

The selected candidate will be part of a multi-disciplinary team as they assess the effect of experimental data on simulation uncertainty in large-scale physics simulations. This will involve collaborating with experimentalists and physics subject-matter experts in order to understand sources and types of uncertainties for a single physics sub-model or experimental setup. The successful candidate will engage in developing probabilistic optimization methods related to uncertainty in model forms, developing uncertainty quantification methods for reduced order models using machine learning algorithms and propagating uncertainty through large-scale predictive physics-based simulations. The successful applicant should have a strong background in at least one of the specialty areas of continuous optimization, probabilistic optimization, uncertainty quantification, or machine learning methods. Experience with interpreted languages such as Python, Matlab, or R is required, Python experience being the most desirable.

What You Need

Minimum Job Requirements:

  • Research-level expertise in optimization, uncertainty quantification, or machine learning, or a closely related focus area.

  • Experience using/developing physics codes

  • Strong programming skills in Fortran, C++ and/or Python. Alternately experience programming in Matlab or R may be substituted.

  • Familiarity with Unix

  • Proficient with software engineering tools like: version control systems; web-based software repository systems; issue trackers; online collaboration platforms; and continuous integration systems

  • Demonstrated ability to publish research in peer-reviewed journals or conference proceedings, communicate research to an interdisciplinary audience and work on an interdisciplinary team

Desired Skills:

  • Experience as developer or advanced user for continuum physics codes.

  • Experience using and/or developing LANL’s Advanced Simulation and Computing Program computational physics codes xRage and/or FLAG.

  • Experienced with modeling/implementing high explosives, equations-of-state and/or radiation transport models in LANL codes

  • Familiarity with and demonstrated interest in LANL’s mission and research environment.

  • Familiarity with Machine Learning packages such as TensorFlow and Scikit-learn

  • Familiarity with using High Performance Compute clusters

  • Experience with version-controlled code projects

  • Ability to obtain a Q clearance

Education: PhD in mathematics, physics, computer science, engineering, statistics, machine learning or a closely related discipline.

Notes to Applicants: Applicants must submit a CV, contact information for three references, and a letter of interest describing how they meet the required and desired qualifications for the position. Recent Ph.D. applicants not meeting all the requirements for the Scientist 2 position may be considered for a postdoctoral appointment.

Additional Details:

Q Clearance: Applicants selected will be subject to a Federal background investigation and must meet eligibility requirements

  • for access to classified matter.

  • Eligibility requirements: To obtain a clearance, an individual must be at least 18 years of age; U.S. citizenship is required except in very limited circumstances. See DOE Order 472.2 for additional information.

New-Employment Drug Test: The Laboratory requires successful applicants to complete a new-employment drug test and maintains a substance abuse policy that includes random drug testing.

Candidates may be considered for a Director's Postdoc Fellowship and outstanding candidates may be considered for the prestigious Richard P. Feynman, Darleane Christian Hoffman, J. Robert Oppenheimer, or Frederick Reines Distinguished Postdoc Fellowships.
