Postdoctoral Appointee Geoscience Engineer

Employer:  Sandia National Laboratories
Job Number:  4018536 (Ref.#. 654287)
Date Posted:  07/18/2016
Application Deadline: Open Until Filled

Job Description

: The Geochemistry Department at Sandia National Laboratories (Albuquerque, New Mexico) seeks a postdoctoral research scientist to investigate the effects of nano-scale confinement on the mineral-water interfacial processes. This project will entail working with meso-porous materials, addressing redox and adsorption reactions, designing and running laboratory experiments, analyzing data and writing publications. This position provides close collaboration with computational chemists at the Geochemistry Department at Sandia in order to develop a molecular-scale understanding of the emergent behavior at the mineral-water interface under nano-scale confinement. There will be opportunities to grow and develop various aspects of the project. On any given day, you might be called on to: + Design and perform laboratory experiments, and analyze collected data + Write research manuscripts + Conduct work in a multi-disciplinary team environment + Attend and present at technical conferences or program meetings 

Required:
+ A Ph.D. (within the last five years) in materials science, chemistry, geochemistry, chemical engineering, or a related discipline with experience in experimental and analytical work. 

Desired:
+ Relevant background in aqueous speciation analysis and synchrotron-based X-ray Absorption Spectroscopy. 

Department Description:

The Geochemistry Department has expertise in three areas: 1) molecular-scale modeling, 2) experimental geochemistry, and 3) applied environmental/chemical engineering. We tackle geosciences-related problems with an application for carbon sequestration, unconventional oil and gas recovery, nuclear waste management, and environmental remediation. In addition, we reach beyond the subsurface environment looking at nuclear weapons applications and air-borne contaminant detection and removal. Program focus is currently on chemical effects on fracture initiation and propagation, heterogeneous redox chemistry on clay mineral surfaces, coupled geochemistry and geomechanics in shales, and permeable reactive barriers for soil radionuclide remediation. Computing facilities for molecular modeling include a cluster (CPU nodes, GPU nodes) maintained by the Geochemistry Department as well as the Sandia High Performance Computing. In addition, we have 3,000 ft2 of laboratory space that includes the following analytical equipment: XRD, FTIR, ICP-MS, ICP-OES, TOF-MS, and SEM.

Security Clearance:

No clearance required. This position does not currently require a Department of Energy (DOE)-granted security clearance. Sandia will conduct a pre-employment background review that includes personal reference checks, law enforcement record checks, and employment and education verifications. Further, employees in New Mexico must pass a U.S. Air Force background screen for access to the work site. 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, rendering the inability to perform the duties assigned and resulting in termination of employment. If hired without a clearance, and one subsequently becomes required or you bid on positions that require a DOE-granted security clearance, a pre-processing background review that includes personal reference checks, law enforcement record and credit checks, and employment and education verifications may be conducted prior to a required federal background investigation. Applicants for DOE-granted security clearances must be U.S. citizens and be able to obtain and maintain the appropriate DOE security clearance as required for the position. 

EEO Statement:

Equal opportunity employer/Disability/Vet/GLBT : 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.
