The Applied Systems Analysis and Research Department (8844) is seeking a
hardworking and dedicated R&D, Geosciences Engineer to join our
multidisciplinary team of scientists and engineers who are passionate about
their work. We need someone to help develop innovative solutions for
numerical simulation of the processes affecting radionuclide mobilization
and transport in the subsurface while working in a fast-paced environment.
The selected applicant will use state-of-the-art software tools and
high-performance computing to build a sound technical basis for and improve
confidence in multiple deep geologic disposal options for nuclear waste.

Are you ready to put your knowledge, skills, and experience to work crafting
creative solutions to challenging problems that impact the nation? You will
join this upbeat team of engineers and embark on a rewarding career\!

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

*	Advance understanding and prediction of radionuclide mobilization
and transport in the geologic systems, engineered barriers, and waste forms
that comprise generic disposal reference cases.
*	Develop, verify, and validate subsurface flow and reactive transport
models, including multi-fidelity modeling approaches.
*	Identify simulation needs and collaborate with software developers
to advance capability.
*	Address uncertainty arising from modeling assumptions, uncertain
inputs, and stochastic variation.
*	Develop Python scripts for pre- and post-processing, visualization,
and analysis.
*	Conduct simulations and analyses in a high-performance computing
environment.
*	Prepare detailed presentations and publications.
*	Travel to conferences and project meetings.

Required:

*	Masters degree in Geoscience, Geosciences Engineering or other
relevant degree plus at least one year of related experience; OR equivalent
combination of education and experience;
*	Proven ability to conduct research and development;
*	Numerical simulation/modeling experience;
*	Ability to obtain and maintain a DOE L-level security clearance.

Desired:

*	PhD in Geoscience, Geosciences Engineering, or other relevant
degree;
*	Experience with numerical simulation of aqueous geochemistry using
simulators such as EQ3/6, PHREEQC, Geochemists Workbench, etc. and/or;
*	Experience with numerical simulation of flow and reactive transport
in porous media using simulators such as PFLOTRAN, CRUNCH-FLOW, FEHM,
TOUGH-REACT, etc.;
*	Experience conducting simulation and analysis in a Linux or Unix
environment;
*	Experience programming and/or scripting for scientific analysis
using languages such as Python, C, C\+\+, Fortran 2003, etc.;
*	Demonstrated ability to integrate information, datasets, and methods
from multiple disciplines such as geohydrology, geochemistry, geomechanics,
statistics and numerical methods;
*	Proven ability to succeed through teaming with others;
*	Excellent interpersonal and communication skills and a demonstrated
ability to develop technical ideas and results and present them in oral and
written form;
*	Ability to work in a fast-paced environment with ever changing
priorities.

Department Description:

The Applied Systems Analysis and Research Department develops a wide range
of software and engineering solutions to ensure the safe deep geologic
disposal of commercial spent nuclear fuel and US DOE legacy nuclear wastes.
We develop high performance computing, quality-assured software for
probabilistic performance assessment of deep geologic disposal systems,
including tools for simulation of the coupled processes affecting
radionuclide release and transport in the subsurface, sampling-based
uncertainty and sensitivity analysis, and automated run-control. We conduct
experiments at an underground research laboratory in bedded salt to
characterize features and investigate processes affecting repository
performance; and partner with adjacent departments and colleagues throughout
the national lab complex to integrate mechanistic models of the physical and
chemical processes affecting engineered and natural barrier systems into
total system performance assessments of generic repositories in a variety of
host rock environments.

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.
