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 needs to 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.


We are a broad team of geophysicists, Earth scientists, engineers and computer scientists working together to increase our understanding of the Arctic coastal and marine geosystem. We are looking for a postdoc to join this dynamic team of scientists and researchers and conduct novel research that spans multiple disciplines in the physical sciences, engineering, and scientific computing. We seek to increase the understanding of the Arctic region: coastal processes, the submarine environment, and sea-ice. Our techniques involve high-performance numerical modeling and advanced data analysis to understand and make probabilistic forecasts and predictions in the Arctic sea-ice, coastal, and marine geosystem. We use methods such as machine learning, sensitivity analysis, and uncertainty quantification to upscale local model predictions, enabling intelligent and informed decision making at the regional and circum-Arctic scales.

On any given day, you may be called on to:

+ Support efforts to run multi-physics simulations of Arctic-focused sea-ice, coastal, marine, and environmental processes;
+ Develop or aid in scientific computing through scripting or programming using Matlab, Python, C, C++, and/or Fortran;
+ Perform mathematical analysis (sensitivity analysis and/or uncertainty quantification) of physics-based modeling and simulation results and/or observational data;
+ Enable an understanding of large, complex data in direct support of Arctic centered work, with the goal of upscaling local and regional models;
+ Collaborate on research papers, reports and presentations.

_This position requires some travel (2-3 times per year)._


+ PhD in Mathematics, Physics, Earth Sciences, Computer Science, or a related area;
+ Experienced in the application of scientific programming and scripting in Matlab, Python, C, C++, and/or Fortran;
+ Experience with sensitivity studies and uncertainty quantification;
+ Evidence of strong research achievements in relevant technical areas as proven in the form of technical publications, presentations, software tools, and/or knowledge of applications.


+ Experience in modeling Arctic sea-ice, permafrost, coastal erosion, marine geosystems, natural gas hydrate systems, or sedimentary systems;
+ Knowledge and interest in statistical analysis techniques and applications, such as machine learning algorithms, correlation, data uncertainty, etc.;
+ Knowledge and interest in data analytic techniques for upscaling to regional and global models;
+ Experience in analyzing sensor data, including multi-source data integration;
+ Research experience in multi-scale/multi-physics simulations;
+ Experience in a research environment working with a team of multi-disciplinary scientists;
+ Proven communication skills;
+ Ability to obtain and maintain a DOE security clearance.

Department Description:

The Geophysics Department at Sandia National Laboratories performs geophysics research and development in support of Sandia's mission as a national security laboratory. We apply our expertise to address national-level challenges in Sandia mission area programs, including nuclear explosion monitoring, energy exploration and resource characterization in support of national energy security, nuclear nonproliferation, defense, homeland security, and nuclear weapons. The department has a broad range of expertise in field seismology and modeling, subsurface characterization, seismic, electromagnetic, atmospheric acoustic and infrasound modeling, evaluation of seismic and infrasound sensors and systems, and the processing, analysis, and interpretation of all types of geophysical data. The department's technical work spans the spectrum from theoretical to applied and includes strong modeling, lab, field data collection, and analysis capabilities. The department serves as Sandia's resource for geophysics expertise.

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.
