Rivian
Marketplace Drive, Irvine
$154,000 - 192,500
Requirements
Must:
- Bachelors degree in Mechanical Engineering, Automotive Engineering, or a related field with over 5 years of pertinent experience in automotive CAE/Durability.
- Profound knowledge of explicit finite element analysis (FEA) with substantial hands-on experience utilizing LS-DYNA for full-vehicle dynamic simulations.
- Advanced understanding of explicit simulation requirements, including energy plot verification, time step control, and mass scaling.
- Strong foundational insight into vehicle suspension systems and overall vehicle dynamic behavior.
- Proven capability in correlating simulation models with physical test outcomes.
- Excellent written and verbal communication skills, particularly in producing high-quality technical documentation.
- Familiarity with implicit solver software such as Abaqus, OptiStruct, or Nastran for structural durability analysis is advantageous.
- Proficiency in pre-processing tools like ANSA and/or Hypermesh is a plus.
- Knowledge of scripting languages (Python, MATLAB) for post-processing and automation is a plus.
- Experience with durability or crash-oriented load case derivation and standardization is an asset.
- Must be at least 21 years old.
- No driving-related suspensions or revocation of Driver License within the last 3-5 years.
- No drug or alcohol-related driving incidents in the past 3 years.
- No more than one serious moving violation in the last 3 years.
- Valid drivers license in the state of residence required for vehicle operation.
- Subject to continuous Motor Vehicle Record (MVR) monitoring.
Responsibilities
- Oversee the setup, execution, and analysis of intricate, full-vehicle explicit dynamic simulations using LS-DYNA.
- Create and scrutinize critical scenarios including underbody ground strikes and extreme strength load cases.
- Manage and calibrate LS-DYNA material cards, ensuring accurate replication of ductile failure and erosion in vehicle structures.
- Rigorously assess simulation results, conducting meticulous checks of energy plots, mass scaling, and solution parameters to confirm numerical stability and precision.
- Lead the correlation between simulation models and physical test results, striving for a true representation of real-world behavior.
- Collaborate with physical testing teams to provide guidance on test setup, instrumentation, and boundary condition definitions.
- Innovate and enhance methods to optimize LS-DYNA processing times for extensive full-vehicle models without sacrificing accuracy.
- Offer flexible support for structural durability CAE simulation tasks employing implicit solver technology when necessary.
- Prepare clear, coherent technical reports that communicate complex simulation findings into actionable insights for stakeholders.
- Utilize pre-processors like ANSA and Hypermesh for model assembly, meshing, troubleshooting, and preparation of model decks.
