What Your Job Will Be Like:

We are seeking a highly motivated and driven postdoctoral appointee to join a multidisciplinary team focused on a multiscale effort to predict metallic microstructure evolution and mechanical failures in extreme environments. Ideal candidates will be creative problem solvers with a solid foundation in uncertainty quantification, AI/ML, and materials modeling, along with experience in scientific computing, as demonstrated by relevant publications and code contributions.

On any given day, you may be called on to: conduct research to develop effective supervised and unsupervised learning algorithms to facilitate large-scale computational studies of phase field and polycrystalline structure evolution. The selected candidate will work closely with Sandia Principal Investigators and will also collaborate with scientists from other national laboratories and universities involved in the project.

Due to the nature of the work, the selected candidate must be able to work onsite.

Qualifications We Require:

• PhD in a field of physical sciences, applied mathematics, engineering, or other relevant field conferred within five years prior to employment.
• Knowledge and expertise in machine learning and/or uncertainty quantification.
• Knowledge and expertise in computational science and/or software development.

Qualifications We Desire:

• Proficiency in using open-source machine learning libraries such as PyTorch or JAX for developing, training, and deploying advanced machine learning models tailored to complex scientific problems.
• Expertise in operator learning and generative models with a focus on their applications in the physical sciences.
• Experience with reduced order modeling and latent space representations.
• Strong programming skills in C++ and Python and integration of machine learning solutions into existing scientific workflows.
• Collaborative research experience.
• Excellent interpersonal and communication skills.

About Our Team:

The Quantitative Modeling and Analysis Department conducts research, development, and systems engineering in computer science and engineering to address important, complex national security problems. Key research areas include uncertainty quantification, optimization, inference modeling, data analysis, and algorithm development. Much of our application development work focuses on verification, validation and uncertainty quantification of complex problems. We provide trusted design and software development for large, operations software as well as detailed scientific computing software. The work is focused on providing efficient, validated information and technologies for use in predictive modeling and decision making.

Posting Duration:

This posting will be open for application submissions for a minimum of seven (7) calendar days, including the ‘posting date’. Sandia reserves the right to extend the posting date at any time.

Security Clearance:

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.

EEO:

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.

NNSA Requirements for MedPEDs:

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.
