Job Description

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. : We are a broad team of computational and atmospheric scientists at the Computer Science Research Institute (CSRI) working together to develop improved atmospheric models (dynamical cores) for the atmospheric component of the Energy Exascale Earth System Model (E3SM), which is a flagship, state of the art Earth System model developed by the Department of Energy. Our team seeks to improve the atmospheric dynamical cores used in E3SM, through the development of novel spatial and temporal numerics that offer increased computational performance and simulation quality. The initial project for this position will be working on time-stepping schemes for a new cloud resolving model (CRM) being developed as part of the E3SM multiscale modeling framework (E3SM-MMF) project. Specifically, we are interested in exploring both semi-implicit and structure-preserving approaches for the anelastic and fully-compressible equations. However, as funding allows, there is flexibility to work on other projects and take the time to grow expertise in a new research area under mentorship of our team and other CSRI staff. More generally, we are looking for a post-doc who would like to join our team and conduct novel research that spans multiple fields in the physical sciences, engineering, and scientific computing; and who will enjoy continued learning, working on research teams, and helping to develop new ideas. Our team, and CSRI more generally 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, we are actively recruiting applicants from a diverse group of backgrounds and who are committed to fostering an inclusive community. On any given day, you may be called on to: + Conduct innovative research in scientific computing in the context of atmospheric modeling, broadly defined, individually or as part of a research team + 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 + Develop or aid in scientific computing through scripting or programming using Python and/or C++ + Collaborate on research papers, reports and presentations This position has the possibility of travel to participate in workshops and conferences.

+ PhD in applied mathematics, physics, computational science, physics, computer science, atmospheric sciences, or a related engineering or scientific area. + Experience with numerical methods for solving partial differential equations (PDEs), such as finite element or finite volume methods + Experienced in the application of scientific programming and scripting in Python, C, C++, and/or Fortran + Proven track record to team in an interdisciplinary R&D environment, including evidence of strong research achievements in relevant technical areas as shown in the form of technical publications, presentations, software tools, and/or knowledge of applications (Publication list should be included as part of the CV)

+ A dedication to fostering an inclusive culture, as proven in your application materials + Experience with implicit and/or semi-implicit time-stepping schemes + Experience with structure-preserving numerical discretizations + Experience in atmospheric model (dynamical core) development + Experience in high-performance computing and coding for new computer architectures

Department Description:

The Computational Science Department performs leading-edge software development and technical analysis through physics-based modeling and simulation, using our applications expertise as 'power users' to guide software development at Sandia's Center for Computing Research. Our goal is to establish first-of-a-kind uses of this software in diverse applications of national importance, ranging from nuclear stockpile stewardship to global climate modeling, and spanning multiple fields of the physical sciences and engineering. As both developers and analysts, we act as a bridge to set a standard for computational simulation for the broader user community and to incorporate critical feedback from users for continuous improvements in our software development activities and products. Join us and work towards your goals while making a difference!

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 Statement:

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. : 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.
