Safety CAE Modeling Engineer - GM Defense
About The Position
This engineer will create and maintain computer-aided engineering (CAE) models for assigned GM Defense Virtual Design, Development and Validation (VDDV) projects, with a primary focus on LS-DYNA model development. The role will support model preparation, execution, post-processing, documentation, and issue resolution for vehicle and component-level analyses. The engineer will work within established GM modeling processes, coordinate with design, analysis, materials, program, and simulation teams, and apply sound engineering judgment to resolve non-routine modeling issues. The role will also contribute to process improvements and automation that improve model quality, repeatability, and delivery timing.
Requirements
- Bachelor's degree in Engineering or Physics
- 3+ years of relevant experience in CAE, FEA, vehicle engineering, or a related technical field
- Ability to use sound engineering judgment, collaborate with cross-functional teammates, and seek guidance when requirements or methods are unclear
- Basic scripting capability in Python, Tcl/Tk, or similar tools to automate repetitive tasks and improve modeling efficiency
- Experience developing LS-DYNA models and using pre- and post-processing tools such as ANSA or Primer
- Experience using engineering software such as Siemens NX, Teamcenter, or visualization tools to support model creation
- Effective interpersonal and communication skills, written and oral, for working with engineering and program stakeholders
- DFSS black belt or similar certification
- Candidate must be a U.S. Person (U.S. citizen, U.S. permanent resident, asylee or refugee).
Nice To Haves
- Demonstrated proficiency in FEA modeling tools
- Experience directly with ANSA as the pre-processing tool for modeling support
- Engineering design and release experience
- Optimization integration into product design and development
Responsibilities
- Create, update, and quality-check CAE (computer-aided engineering) models using established GM modeling standards.
- Prepare LS-DYNA models and perform pre-processing and post-processing for assigned vehicle and component-level analyses.
- Review model quality and results for completeness and consistency; document assumptions, findings, and open issues.
- Identify and resolve non-routine modeling issues using engineering judgment, escalating issues outside established methods.
- Apply established modeling procedures to GM Defense requirements and escalate proposed deviations for review.
- Coordinate with designers, design release engineers (DREs), materials specialists, simulation engineers, and program teams to obtain inputs and resolve issues.
- Communicate model status, risks, issues, and timing to project stakeholders.
- Support assigned analyses in applicable vehicle safety, occupant, rechargeable energy storage system (RESS), crashworthiness, instrumentation, and sensing domains.
- Contribute to process automation using Python, Tcl/Tk, or similar scripting tools.
- Share modeling methods and lessons learned with teammates and recommend improvements to modeling processes, tools, and documentation.
