Sandia National Laboratories Intern - Computational Modeling R&D Grad Year Round in Livermore, California

:

We are seeking an Intern - Computational Modeling R&D Grad Year Round

As a Computational Modeling Grad Student in Sandia's Thermal/Fluid Science & Engineering Department you will develop models and computational methods for the simulation of complex reacting flows and heat transfer in porous media. You will implement new multi-physics models in Sandia simulation codes and work with analysts and experimentalists. Applications of particular interest include the combustion of organic materials and surface reactions for hydrogen storage. In this position, you will be able to expand modeling capabilities to impact several of Sandia’s key mission areas, including nuclear stockpile safety and energy security. External publication of research and analysis work is encouraged. As a member of our team, you will interact closely with engineers and other researchers and analysts across the California and New Mexico sites.

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

  • Work on a number of modeling and computational R&D projects concurrently
  • Collaborate across several diverse teams

:

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.

Required:

You bring the confidence and skills to be eligible for the job by meeting these minimum requirements:

  • Earned bachelor's degree
  • Currently attending and enrolled full time in an accredited science, engineering, or math graduate program
  • Minimum cumulative GPA of 3.0/4.0
  • Ability to work up to 30 hours per week during the academic year, and up to 40 hours per week during the summer
  • U.S. citizenship

Desired:

  • Graduate student working toward a degree in aerospace engineering, mechanical engineering, chemical engineering, material science, computer science, applied mathematics, or a closely related field
  • Knowledge and experience with computational modeling of heat transfer, fluid dynamics, pyrolysis chemistry, and/or porous media flows
  • Knowledge and experience with the physics related to surface reactions and material property models
  • Knowledge and experience with the physics relating to gas and solid phase combustion
  • Experience in processing data and handling large quantities of data
  • Proficiency in a data plotting/manipulation language (ex: Matlab, Python, or similar)

Department Description:

Sandia/California's Thermal/Fluid Science and Engineering Department is a multidisciplinary group of engineers and researchers who specialize in fluid mechanics and heat and mass transfer. The work mix in the group includes developing theory and models, performing scientific and high-performance computing, and executing applied engineering analysis for a range of experiments and mechanical designs. The group plays two primary roles in science-based engineering at Sandia: (1) developing new computational methods, capabilities and tools to describe fluid mechanics and heat transfer; (2) performing computational analysis to predict the design performance of engineered systems in defense, energy, and industry applications. Recent activities within the group include heat transfer modeling, porous media reacting flow modeling, multi-phase flow modeling, battery modeling, hydrogen storage and safety technology, fluid dynamics modeling, combustion and heat transfer modeling, turbulent heat transfer simulation, and applied uncertainty quantification to all of these application areas.

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.
