Are you passionate about developing models in support of a digital twin effort for nuclear weapons? Do you see value in architecting new concepts in modeling and simulating before developing systems and components? If so, you will want to apply for this opportunity to join a team of systems thinkers in applying modeling to various aspects of the nuclear weapon development lifecycle. We are seeking to fill multiple Research & Development; Science & Engineering, Computer Science positions.

Model Based Systems Engineering (MBSE) and Model Based Design (MBD) for a Digital Twin has become a critical focus for US Navy (USN) nuclear and conventional weapon programs, the Air Force Nuclear Weapons Center, and the Department of Defense’s Digital Engineering Strategy. We are expanding our core team of MBSE modelers to support existing and future programs, such as the W80-4 warhead development, W87-1 warhead, and other NNSA supported nuclear deterrence programs. This team is developing new concepts of integrated models to allow for faster design engineering approaches and thus leading to virtual design lifecycles instead of the design-build-test approach of legacy programs.

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

  • Model NW system and component behavior and integrate that with other developed models such as kinematics, electrical circuit modeling, finite element, heat transfer, and various other techniques.
  • Use physical and computational simulation, analysis, and evaluation as inherent activities of verification and validation
  • Develop visualizations for Data Science and Analytics
  • Develop Hardware in the Loop concepts for NW components
  • Develop a capability for automated test vector generation to be applied in NW
  • Develop functional, physical, interface, and environmental information using MBSE/SysML
  • Perform Concept of Operations Development, Requirements Analysis and Definition, Trade Studies, Design Analysis, Interface Design & Assessment, Integrated System Test Planning, System Verification & Validation, and Configuration Management
  • Design the technical solution in SysML models for various weapon systems and components including, but not limited to the W80-4, Electronic Neutron Generators, Mk21 Fuse, and the W87-1
  • Develop, implement, and maintain modeling architectures and models to support Advanced and Exploratory (2441) projects
  • Conduct technical review sessions with peers and relevant SME’s to improve functional models and develop associated requirements
  • Lead R&D conceptual system trade studies for NW related programs.
  • Develop or work with a team to develop digital infrastructure in support of these activities
  • Perform data science activities

Department Description:

The MBSE department has responsibility to provide system-level leadership for the advanced modeling and systems engineering activities necessary to support current and upcoming nuclear weapon needs. The department supports integration of these approaches into the engineering infrastructure, through collaborative efforts with our Sandia partners, including 2441 (Advanced and Exploratory NM), 8425 (Advanced and Exploratory Systems CA), and all system and component organizations.

  • Familiarity with NW Product Realization Teams, 6.X Product Realization process or Product Definition system (PRIME/IMS)

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 must 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 DOE security clearance, a pre-processing background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications may be conducted prior to a required federal background investigation. Applicants for a DOE security clearance must 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.
