Our team is seeking a postdoctoral appointee at the Computer Science Research Institute with a strong background in the development of numerical methods for solving problems in computational science, machine learning (ML), or high-performance computing (HPC). The successful candidate will contribute to an effort developing numerical methods for training deep neural networks on leadership class HPC platforms. This work is targeting applications in scientific machine learning, where the appointee will work in a team of scientists to apply their training methods and neural network technologies to problems of broad interest to the science and engineering community, including applications in climate science and plasma physics. 
We are 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
• Work with export-controlled information which requires US Person status

Qualifications We Require

• Possess, or are pursuing, a PhD in mathematics, computer science, or related engineering or science field (conferred within 3 years prior to employment)
• Familiarity with optimization or deep learning, as evidenced by either completion of a graduate class that covered optimization or deep learning, or use of optimization or deep learning in a research setting.
• Experience in numerical methods development in a research setting, with either released code and/or a published paper on this work

Due to U.S. export-control laws, only U.S. Persons (U.S. citizens, lawful permanent residents, asylees, or refugees) are eligible for consideration.

Qualifications We Desire

• Experience with high-performance parallel computing environments, including having written code using MPI, OpenMP or CUDA.
• Experience with multi-level methods, domain decomposition, matrix sketching, or hiearchical matrices
• Experience with Tensorflow/pyTorch, and the application of machine learning (ML) techniques to large datasets
• Passion around applying machine learning and computational methods to problems in science and engineering
• Strong written and oral communication skills
• A dedication to encouraging an inclusive culture, as proven in your application materials
• Proven track record teaming in an interdisciplinary R&D environment
• Significant experience in code development, potentially including software design using object-oriented programming, high-performance computing, distributed or parallel computing, and/or coding for computer architectures
• A background in solving problems in science and engineering that involve encounters with 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
• Able to acquire and maintain a DOE security clearance

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. We 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.

Join us and work towards your goals while making a difference!
 

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 three 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.

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.
