WHAT YOUR JOB WILL BE LIKE:

We are seeking postdoctoral appointees at the Computer Science Research Institute with a strong background in the development of numerical methods for solving problems in computational science and/or machine learning (ML). You will join the SEA-CROGS project (PI is G. Karniadakis at Brown University) that seeks to develop a paradigm shift in our computational capability to analyze and predict the behavior of complex systems. You will develop novel hierarchical neural network architectures, causal inference methods, or training techniques emphasizing the structure inherent in scientific data. This effort is integral to an envisioned distributed scientific machine learning ecosystem leveraging a range of computing platforms from HPC to edge devices. The postdoctoral appointee will help to lay the foundation for this ambitious vision, and push themselves and Sandia towards the forefront of scientific machine learning research.

The Computer Science Research Institute is committed to nurturing a culture compatible with a broad group of people and perspectives in accordance with the changing makeup of the workforce. In support of this vision, the center actively recruits applicants from diverse groups of backgrounds and fosters an inclusive community.

In this role, you will work collaboratively on a multidisciplinary research team conducting fundamental algorithmic research. On any given day, you may be called on to:

Conduct leading-edge research in Scientific Machine Learning (SciML).

Work towards publishing new developments in high-profile peer-reviewed scientific journals or refereed conference proceedings; contribute to development of open-source software for high performance computing environments.

Interact with a diverse set of colleagues from both your own field, applications specialists, and others.

Travel as needed to support projects.

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.

QUALIFICATIONS WE REQUIRE:

PhD in mathematics, computer science, or related engineering or science field (conferred within 3 years prior to employment)

Experience with machine learning or numerical methods development

QUALIFICATIONS WE DESIRE:

Experience with multi-level methods, domain decomposition, matrix sketching, or hiearchical matrices

Experience with causal inference techniques

Experience with Tensorflow/pyTorch, and the application of machine learning (ML) techniques to large datasets

Experience with backpropagation free neural network training

Strong written and oral communication skills

A dedication to encouraging an inclusive culture, as demonstrated in your application materials

Proven track record teaming in an interdisciplinary R&D environment

A background in solving problems in science and engineering that requires integrated real world data

Proven research community leadership through activities such as participation in student or professional organizations, service on committees, workshop and/or conference organization, and editorial roles

ABOUT OUR TEAM:

The Computational Mathematics Department (01442) conducts research in computational and applied mathematics motivated by science and engineering applications of interest to Sandia National Laboratories and the U.S. Department of Energy. Members of the department interact and collaborate with a broad range of Sandia and DOE staff and also maintain a research presence in the external professional community by collaborating with universities and industry, publishing peer-reviewed literature, participating in professional societies, and refereeing and editing for journals.

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:

This position does not currently require a Department of Energy (DOE) security clearance.

Sandia will conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Furthermore, employees in New Mexico need to pass a U.S. Air Force background screen for access to Kirtland Air Force Base. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause access to be denied or terminated, resulting in the inability to perform the duties assigned and subsequent termination of employment.

If hired without a clearance and it subsequently becomes necessary to obtain and maintain one for the position, or you bid on positions that require a clearance, a pre-processing background review may be conducted prior to a required federal background investigation. Applicants for a DOE security clearance need to be U.S. citizens. 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.

Members of the workforce (MOWs) hired at Sandia who require uncleared access for greater than 179 days during their employment, are required to go through the Uncleared Personal Identity Verification (UPIV) process. Access includes physical and/or cyber (logical) access, as well as remote access to any NNSA information technology (IT) systems. UPIV requirements are not applicable to individuals who require a DOE personnel security clearance for the performance of their SNL employment or to foreign nationals. The UPIV process will include the completion of a USAccess Enrollment, SF-85 (Questionnaire for Non-Sensitive Positions) and OF-306 (Declaration of for Federal Employment). An unfavorable UPIV determination will result in immediate retrieval of the SNL issued badge, removal of cyber (logical) access and/or removal from SNL subcontract. All MOWs may appeal the unfavorable UPIV determination to DOE/NNSA immediately. If the appeal is unsuccessful, the MOW may try to go through the UPIV process one year after the decision date.

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.

Position Information:

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.
