Job Description


We are seeking a technical staff member who will perform thermal, fluid dynamics and/or reacting material \(solid decomposition, gas phase combustion, fire\) research, development, modeling, and simulation to support a variety of projects \(e\.g\. nuclear safety and design and energy related research\)\. The successful candidate will use and potentially develop state\-of\-the\-art tools to conduct computational simulations for one or more of the following application areas: conductive, convective, radiative transport, reacting flow, porous media flow and heat transfer, and thermal decomposition\.

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

+ Apply and develop uncertainty quantification techniques for these problems\.
+ Work closely with code developers, analysts, and experimentalists to provide validated results of extremely complex and challenging problems\.
+ Work on several different projects concurrently and must work across several diverse teams\.
+ Interact closely with engineers and other researchers and analysts across the laboratory at both the California and New Mexico sites\.


+ Master's degree, or higher, in mechanical, chemical, aerospace engineering or closely related field \(applied math, etc\);
+ Strong educational background in one or more of the following areas: heat transfer \(including conduction, convection and radiation\), reacting materials/chemistry/combustion;
+ Experience with modeling and simulation tools \(e\.g\., the finite\-element method\); ability to assess tool capabilities and limitations when selecting the appropriate methodology for model development and simulation;
+ Ability to obtain and maintain a US DOE Q security clearance\.


+ Ph\.D\. degree in mechanical, chemical, aerospace engineering or closely related field \(applied math, etc\);
+ Minimum undergraduate 3\.2/4\.0 GPA; graduate 3\.5/4\.0 GPA;
+ Demonstrated ability to master new application areas
+ Demonstrated ability to work in a team environment;
+ Demonstrated experience with statistical methods and uncertainty quantification;
+ Demonstrated ability to present and publish research findings and make original contributions to engineering science;
+ Excellent verbal and written communication skills;
+ Demonstrated experience in computational mechanics or code development for engineering sciences applications and high performance computing;
+ Demonstrated programming proficiency \(e\.g\. C\+\+, python, Fortran, C\);
+ Experience with multiphase flow\.

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\.
