Bidder Eligibility:

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.

Employees, excluding student interns, must remain in their current position for one year from their hire date before bidding on a new job. However, the hiring manager may obtain approval to consider a candidate before the one-year requirement is met via the review process. This approval must be secured prior to being interviewed for a posted position. The application of this requirement will not supersede collective bargaining agreements. Please refer to the collective bargaining labor agreements for eligibility requirements for represented bidders.

What Your Job Will Be Like:

We are seeking a Postdoctoral Appointee with expertise and interest in large-scale atmospheric dynamics, including stratospheric transport and impacts. You will work in an interdisciplinary team to develop novel computational approaches that capture quantitative relationships between multiple variables over space and time. As an Earth system scientist in Sandia's Atmospheric Science department, your work will lie at the interface of climate sciences, computational modeling, data analytics, machine learning, spatiotemporal statistics, optimization, and uncertainty quantification.

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

+ Work with the DOE E3SM and SCREAM models to represent the earth system and atmospheric processes.

+ Develop novel code to improve the representation of the physical processes that govern the stratosphere within E3SM/SCREAM.

+ Characterize the variability and perturbations of stratospheric aerosol and radiative forcing associated with aerosol injections such as volcanic eruptions.

+ Identify atmospheric teleconnections and relationships between natural modes

As a postdoctoral appointee, we will also be expecting and supporting you to:

+ Publish your work in peer-reviewed journals.

+ Present your work at relevant conference venues.

+ Network with other scientists both within and outside Sandia

+ Pursue follow-on research in support of broad-ranging mission areas

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:

+ Recent PhD in Atmospheric or Climate Sciences, or in a related field

+ Proven research experience, as evidenced by strong record of research publications and presentations

+ Experience in climate modeling, analysis, and interpretation

At least one of the following:

+ Running simulations with coupled Earth system models (e.g., E3SM, CESM, GFDL, GISS)

+ Evaluation of climate model performance as encompassed by any of the following: computational performance, predictive accuracy, sensitivity of parameterizations in response to distinct forcings, comparison to observational records

+ Analysis of climate datasets to establish constraints, mechanistic connections, or sensitivity of target quantities to sources of variability (natural or forced)

+ Analysis of climate variability and large-scale dynamics (e.g., El Niño-Southern Oscillation, North Atlantic Oscillation / Polar Vortex, Atlantic Multidecadal Oscillation, Brewer Dobson, Quasi-biennial oscillation)

+ Computer languages used for modeling and analysis (C, C++, Fortran, Python, Julia, R, MATLAB)

Qualifications We Desire:

Expertise in the simulation and analysis of one or more of the following:

+ Stratospheric dynamics

+ Clouds and precipitation

+ Downscaling climate models and regional analysis

+ Internal variability, natural variability, forced variability, and/or inter-model variability

+ Ensemble analysis and coupled global climate models

+ Component model coupling (e.g., land-atmosphere, ocean-atmosphere, sea-ice-ocean) and its influence on dynamics

+ Development of components within climate models (e.g., new parameterizations, alternative computational schemes)

+ Familiarity with high performance computing environments

+ Proven ability to advance the state-of-the-art in climate science-related subject areas and/or related fields of study as is evidenced by original high-impact publications or a high h-index / other citation analysis

+ Ability to conduct self-directed research

+ Ability to work in multi-disciplinary research environments on problems comprising diverse application domains

+ Proven research community leadership through activities such as participation in student or professional organizations, outreach activities, etc.

+ Excellent written and oral communication and interpersonal skills

+ Desire to perform in a dynamic environment and demonstrated interest and/or experience in service to the nation

+ Ability to travel for business and research purposes

About Our Team:

8913 Atmospheric Sciences - The staff in the Atmospheric Sciences Department at Sandia National Labs have expertise in atmospheric measurements and modeling. Technical activities cover the spectrum from theory to application, including algorithm development, computer modeling, data inversion, instrumentation and measurement systems development, field demonstration, field campaign execution, and field site management. Expertise exists in the measurement and modeling of atmospheric processes in the Arctic including the use of unmanned aerial vehicles such as small, fixed wing and rotary aircraft and tethered balloons, as well as the use and cold hardening of measurement systems such as radar and lidar. The department serves as a Laboratories resource for atmospheric sensing expertise.

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:

Sandia is required by DOE to conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Applicants for employment need to be able to obtain and maintain a DOE Q-level security clearance, which requires U.S. citizenship. 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.

Applicants offered employment with Sandia are subject to a federal background investigation to meet the requirements for access to classified information or matter if the duties of the position require a DOE security clearance. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause a clearance to be denied or terminated by DOE, resulting in the inability to perform the duties assigned and subsequent termination of employment.

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.
