What Your Job Will Be Like:
We are seeking a technical staff member (job title: R&D S&E Mechanical Engineer) to join a collaborative team that uses state-of-the-art analytical and computational simulation techniques to perform first-of-a-kind engineering system analysis and thermal science research with a direct impact on national security. We seek individuals with educational backgrounds and/or professional experience in thermal fluid science (e.g., heat transfer, fluid dynamics) and computational simulation applications or development. The successful candidate will use and potentially develop state-of-the-art tools and models to perform computational simulations in support of applied R&D projects across our national security, nuclear deterrence, and energy mission applications.
On any given day, you may be called on to:
Perform thermal, fluid dynamics and/or reacting material (e.g., solid decomposition, aerothermal ablation, re-entry, gas phase combustion, fire) research, development, modeling, and simulation to support a variety of projects for internal (Sandia) and external customers
Use engineering analysis principles and computational methods to support the design, qualification, and fielding of high consequence engineered systems for national security missions
Use and/or develop state-of-the-art tools and models to conduct computational simulations (e.g., fluid dynamics, turbulent flow, multiphase flow, conductive/convective/radiative transport, thermal-mechanical, reacting flow, porous media flow and heat transfer, and thermal decomposition)
Apply and develop uncertainty quantification techniques and assess model credibility through the application of verification & validation principles
Identify opportunities to modularize, automate, and streamline analysis workflows to reduce repetitive tasks and improve efficiency
Engage with code and model development teams to develop and implement novel models and capabilities for high performance computing algorithms and environments
Collaborate on 'digital thread' initiatives by developing credible, reliable, and well-documented analysis code utilizing modern software best practices
Work closely with teams of code/model developers, analysts, and experimentalists to develop and implement novel models and capabilities for high performance computing algorithms and provide validated simulation results for complex and challenging R&D problems
Serve as a technical bridge and systems-minded connector between physics analysis teams, software development groups, and experimentalists
Collaborate and interact closely with a geographically-dispersed team, including engineers and other researchers and analysts across the laboratory at both the California and New Mexico sites
Due to the nature of the work, the selected applicant must be able to work onsite. The preferred work location for this position is in Livermore, CA; Albuquerque, NM may be considered with regular travel to CA.
Applicants on this posting may be interviewed by multiple organizations at Sandia National Laboratories.

About Our Team:
Sandia/California's Thermal/Fluid Science and Engineering Department is a multidisciplinary community of engineers and researchers who specialize in fluid mechanics and heat and mass transfer. The work mix in the group includes theory and modeling, scientific and high-performance computing, and applied engineering analysis 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, heat transfer, and thermal response; (2) performing computational analysis to predict the design performance of engineered systems in defense, energy, and industry applications. Recent activities and R&D areas within the group include: heat transfer and fluid dynamics modeling and analysis for complex multi-material systems, porous media reacting flow, multi-phase flow, turbulent heat transfer, fire and combustion, hydrogen storage and safety technology, wind energy modeling and technology development, geothermal energy technology, and applied uncertainty quantification and verification and validation for all of these application areas.
Posting Duration:
This posting will be open for application submissions for a minimum of three (3) 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.
