The Component Science and Mechanics Department is seeking a highly motivated mechanical engineer to join our diverse and inclusive team of structural dynamics and solid mechanics computational analysts. In our mission, we support the development of complex mechanical and electrical components through research, development and application of state-of-the-art computational capabilities leveraging some of the world's most advanced high-performance computing (HPC) facilities and codes.

In addition to contributing on our analysis teams, this staff member will develop a robust research portfolio in support of our mission. Research topics of interest include materials mechanics spanning multiple length scales, nonlinear dynamics, fracture, failure, surrogate models, digital twin development, multi-physics simulation, and engineering uses of AI/ML tools and algorithms. At Sandia there is the unique opportunity to collaborate with a broad and diverse range of world experts including mechanical engineers, material scientists, analysts, experimentalists, mathematicians, and computer scientists to develop new methodologies and algorithms to analyze and understand the nonlinear response of engineering structures under complex loading conditions.

On any given day, you will have the opportunity to:

• Use HPC platforms and massively-parallel finite-element software to simulate the nonlinear structural response of systems subjected to complex, multi-physics environments.
• Research advanced topics in nonlinear mechanics.
• Develop new numerical algorithms to solve nonlinear boundary value problems and explore strategies to integrate into finite element software by partnering with code development teams.
• Investigate reduced-order modeling strategies to enable efficient simulations of large-scale engineering models.
• Work closely with the experimental engineers to develop test plans to validate new theories and/or predictions from numerical models.
• Develop a robust research portfolio through peer-reviewed journal publications, conference presentations, and participation in professional societies

Due to the nature of the work, the selected applicant must be able to work onsite. Relocation will be provided for those that qualify.

$117,500 - $235,700

• 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.

• A Bachelor's degree in a relevant discipline and five (5) years of directly relevant experience, or an equivalent combination of directly relevant education and engineering or scientific experience that demonstrates the knowledge, skills, and ability to perform independent research and development.
• Ability to obtain and maintain a DOE Q security clearance

The ideal R&D S&E Mechanical Engineer will in addition possess the following:

• Graduate degree in Mechanical Engineering or a highly related field where an independent research project was a graduation requirement (e.g., independent project, thesis, or dissertation).
• Experience with mechanical engineering and product realization in the NNSA complex.
• Strong verbal and written communication skills, ability to work effectively in multidisciplinary teams.

Also, for this posting, we are seeking individuals with the following experience:

• PhD in Mechanical Engineering, Civil Engineering, Applied Mechanics, Aerospace Engineering, or related field.
• Experience in nonlinear structural mechanics, dynamics and vibrations, including numerical methods, finite element analysis, and modal analysis.
• Experience with development and implementation of numerical methods, uncertainty quantification, and/or model order reduction methods.
• Excellent computer programming and code development skills.
• Knowledge of modern uncertainty quantification methods and approaches.
• Experience with advanced methods to characterize, analyze and understand behavior of nonlinear systems.
• Knowledge of experimental techniques for vibration testing and modal analysis.
• Strong verbal, written and interpersonal communication skills.
• Ability to work independently and to integrate effectively into a dynamic and diverse multidisciplinary team.

The Component Science and Mechanics Department conducts state-of-the-art engineering-mechanics research and develops science-based solutions for component design and assessment. We employ computational and physical simulations-solid-mechanics and structural-dynamics analyses of both linear and nonlinear systems in an agile, multidisciplinary teaming environment. Research and application focus areas include solid mechanics; structural dynamics; materials, interface, contact, and fracture mechanics; bolted-joint analysis; electronic packaging; impact response of mechanisms; advanced stress analysis for predicting fracture and fatigue; joining techniques such as welding and brazing; uncertainty quantification; and model-order reduction. We support customers and team for solutions across Sandia's mission space, delivering expert analysis and knowledge to inform decision makers.

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.

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.
