What Your Job Will Be Like:

We are seeking a dedicated Postdoctoral Appointee to support a new SciDAC project on global climate modeling. The project aims to improve models for the quasi-biennial oscillation through surrogate-accelerated parameter optimization and vertical grid modification. This postdoc will work closely with a large team of scientists that includes collaborators at LANL.

Your job will include:

  • Addressing complex problems in support of broad-ranging applications within climate modeling

  • Collaborating with highly motivated researchers on challenging research questions

  • Presenting your work within leading publications and conference venues

Qualifications We Require:

  • Background that includes research experience as evidenced by peer-reviewed publications and presentations

  • Experience with data-driven surrogate modeling (polynomial regression, Gaussian processes, neural networks)

  • Experience with surrogate-based optimization and UQ, especially for calibration (deterministic: nonlinear least squares, stochastic: Bayesian calibration)

Qualifications We Desire:

  • Ability to work effectively as part of a larger team

  • Familiarity with climate modeling, ideally atmospheric and/or full system modeling

  • Familiarity with large-scale computing software development, C++, Python, and HPC

  • Excellent written and verbal interpersonal skills

  • Experience in machine learning with an emphasis on optimization

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.


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.

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.
