Are you looking to be a member of a highly motivated team? We are seeking a Postdoctoral Appointee in the areas of atomistic materials modeling, machine learning, and high-performance scientific computing. You will address challenges in the development of novel interatomic potentials for molecular dynamics, the creation of multiscale simulation capabilities (e.g., electronic structure, atomistic scale, continuum scale), and the application of machine learning to problems in materials modeling. This position provides the opportunity to collaborate with a diverse set of colleagues including researchers from your own field, applications specialists, and others, and to engage with the broader research community through publications and participation in leading scientific conferences. Join our team of scientists and researchers and make a difference!

• You have, or are pursuing, a PhD in Physics, Chemistry, Mathematics, Materials Engineering, Chemical Science, Computer Science, or related science or engineering field. PhD must be conferred within five years prior to employment.
  
• Experience in research, development, and programming of atomistic materials models, for example electronic structure methods or molecular dynamics.
• Experience in the use of simulation methods to study mechanics of materials, for example fatigue, plasticity, creep, or related phenomena.
• Record of research as demonstrated by publications in peer-reviewed journals or competitive conference proceedings.
• Ability to acquire and maintain a DOE security Q clearance, which requires US citizenship.

• Experience using and developing machine learned models (neural networks, kernel methods, etc.) and mathematical/computational theory of AI/ML.
• Experience with the LAMMPS software package (http://lammps.sandia.gov), both in code development and application.
• Proficiency in C++ and Python software development, code verification, and modern software quality practices.
• Experience with developing and running complex science and engineering codes on massively parallel computing clusters, including GPU+CPU hybrid platforms.
• Interest in impacting applications and customers in support of DOE missions, notably fusion energy science.

The Computational Multiscale Department performs research and development in physics-based materials modeling and high-performance computing. We combine expertise across multiple fields to solve science and engineering problems in support of NNSA and DOE missions. Our team brings together authorities in density functional theory, molecular dynamics, direct simulation Monte Carlo, microstructure modeling, continuum mechanics, and equations of state. We lead a number of software development efforts, including the LAMMPS molecular dynamics code and the FitSNAP machine learning interatomic potential software, and strive to advance the state of the art in materials modeling through a wide range of collaborations across the laboratories.

This posting will be open for application submissions for a minimum of three (3) calendar days, including the 'posting date'. Sandia reserves the right to extend the posting date at any time.

Sandia is required by DOE to conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Applicants for employment need to be able to obtain and maintain a DOE Q-level security clearance, which requires U.S. citizenship. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted.

Applicants offered employment with Sandia are subject to a federal background investigation to meet the requirements for access to classified information or matter if the duties of the position require a DOE security clearance. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause a clearance to be denied or terminated by DOE, resulting in the inability to perform the duties assigned and subsequent termination of employment.

All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, or veteran status and any other protected class under state or federal law.

If you have a Medical Portable Electronic Device (MedPED), such as a pacemaker, defibrillator, drug-releasing pump, hearing aids, or diagnostic equipment and other equipment for measuring, monitoring, and recording body functions such as heartbeat and brain waves, if employed by Sandia National Laboratories you may be required to comply with NNSA security requirements for MedPEDs.

If you have a MedPED and you are selected for an on-site interview at Sandia National Laboratories, there may be additional steps necessary to ensure compliance with NNSA security requirements prior to the interview date.
