Job Description:
Posting Duration:
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.
Salary Range:
*Salary range is estimated, and actual salary will be determined after consideration of the selected candidate's experience and qualifications, and application of any approved geographic salary differential.
What Your Job Will Be Like:
We are seeking a technical staff member (R&D S&E, Mechanical Engineer) to join our collaborative team environment. As an analyst on our team you will perform solid mechanics, structural-dynamics, and/or hydrocode research, development, modeling, and simulation to support a variety of projects (e.g. nuclear safety, design, and qualification, failure, shock and vibration, and/or thermal- mechanical response), and customers (e.g., the Departments of Defense and National Nuclear Security Administration, university collaborations, etc.). Appropriate uncertainty quantification will be used with finite element analysis and other analysis methods to predict component or system behavior under specific operating conditions. Verification and validation of modeling techniques will be used to build model credibility. The analysts in our department work closely with experimental mechanics, code development, and material science organizations to provide validated results of extremely complex and challenging problems that support the design, qualification, and fielding of high consequence engineered systems for national security missions.
On any given day, you may be called on to:
Build finite element and/or hydrocode models of components, sub-assemblies, or full systems and using these models perform non-linear static and dynamic or hydrocode analyses to assess design margins, failure response, design trade studies, fatigue life, system and sub-assembly environments, or provide input to large scale testing for a variety of projects for internal (Sandia) and external customers Perform research, development, and simulations and share results through internal reports, journal publications, conferences, and internal design, testing, and qualification reviews Use engineering analysis principles and computational methods to support the design, qualification, and fielding of high consequence engineered systems for normal and abnormal environments and combinations of environments (random vibration, shock, blast, impact, crash and burn) Apply and develop uncertainty quantification techniques and assess model credibility through the application of verification & validation principles Engage with code and model development teams to develop and implement novel models and capabilities for high performance computing algorithms and environments 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 Collaborate and interact closely with a diverse, 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 75% or more of the time.
Qualifications We Require:
Master's degree in mechanical, civil, applied engineering, or other applicable engineering field, or equivalent experience in lieu of degrees must be engineering or scientific experience that demonstrates the knowledge, skills, and ability to perform independent research and development Educational background in one or more of the following areas: solid mechanics, continuum mechanics, mechanics of materials, structural analysis, structural dynamics, shock and vibration, finite element analysis, numerical methods, mechanics of materials, thermal-mechanical response, large deformations, material failure modeling Experience with modeling and simulation tools (e.g. Abaqus, Solidworks Simulation, Ansys, LS-Dyna, CTH, ALE3D, Simulia, Sierra, Cubit, Paraview, Ensight) Ability to obtain and maintain a US DOE Q security clearance.
Qualifications We Desire:
Ph.D. degree in mechanical, civil, applied engineering, or other applicable engineering field; Demonstrated ability to present and publish research findings; Demonstrated experience in computational mechanics or code development for engineering sciences applications; Proficiency with code development in a modern programming language such as C++ or Python Experience with finite-element methods, continuum and noncontinuum mechanics; Background in mechanical design; Plasticity and material-failure modeling experience. |
