BIDDER ELIGIBILITY

This postdoctoral position is a temporary position for up to one year, which may be renewed at Sandia’s discretion up to five additional years. The PhD must have been conferred within five years prior to employment. Individuals in postdoctoral positions may bid on regular Sandia positions as internal candidates, and in some cases may be converted to regular career positions during their term if warranted by ongoing operational needs, continuing availability of funds, and satisfactory job performance.
Employees, excluding student interns, must remain in their current position for one year from their hire date before bidding on a new job. However, the hiring manager may obtain approval to consider a candidate before the one-year requirement is met via the review process. This approval must be secured prior to being interviewed for a posted position. The application of this requirement will not supersede collective bargaining agreements. Please refer to the collective bargaining labor agreements for eligibility requirements for represented bidders.

WHAT YOUR JOB WILL BE LIKE

We are seeking a Postdoctoral Appointee with a focused background in kinetic Monte Carlo (kMC), Molecular Dynamics (MD), Density Functional Theory (DFT) and/or Dislocation Dynamics (DD) to join our interdisciplinary team of scientists and professionals. Technical areas of focus for this position are applying atomic scale simulations (e. g. kMC, MD, DFT) to study problems such as hydrogen embrittlement in various metallic systems, nucleation and growth mechanisms of helium bubbles, desorption kinetics of metal hydrides, microstructure evolution and mechanical properties of aging structural materials. Such work could include developing accelerated kMC codes as well as interatomic potentials in atomistic simulations. Our work strongly couples both experimental and theoretical approaches to provide innovative and robust solutions. You will have the opportunity to interact with experts in diverse fields.

On any given day you may be called on to:

• Apply fundamental scientific principles in complex material simulations for property estimation and mechanism discovery. This work is expected to lead to the publication of research findings in peer reviewed journal articles and technical reports. Within this work you will have the opportunity to explore modern techniques such as machine learning.

The selected applicant can work a combination of onsite and offsite work. The selected applicant must live within a reasonable distance for commuting to the assigned work location when necessary.
