CAE Engineer II - Interior Trim & Door Systems

Rivian; Tustin (CA); On-site; USD 95,000 - 106,000; Full time

Job summary

Rivian is seeking a CAE Engineer II to own the structural integrity and safety for Interior Trim systems. You will use non-linear dynamic simulations to resolve complex plastic failures, optimize fit and finish, and ensure occupant safety prior to physical testing.

The role requires 3+ years in Automotive Interior CAE, proficiency in LS-DYNA or ABAQUS, and experience with ANSA/HyperWorks/META. Join Rivian’s mission to keep the world adventurous with emissions-free vehicles.

Qualifications

• Bachelors of Science in Mechanical Engineering (or related field).
• 3+ years of Automotive Interior CAE Experience.
• Proficiency in LS-DYNA or ABAQUS for non-linear static, dynamic, and deployment analysis.
• Proficiency in pre/post-processors (ANSA, HyperWorks, META).
• Specialized expertise in interior plastic design guidelines, polymer behavior, and fastener joint integrity.
• Knowledge of Interior Safety/Occupant Protection standards (FMVSS 201/201U, 214, 208/226).

Responsibilities

• Execute High-Fidelity Simulations: Model complex non-linear dynamic, structural, and abuse load cases for Door Trim assemblies, Instrument Panels, Pillars, and Consoles.
• Predict Interior Failure Modes: Predict crashworthiness, airbag deployment dynamics, door slam durability, step loads, and clip-on/snap-fit insertion/extraction forces.
• Non-Linear Polymer Analysis: Evaluate injection-molded plastics, foams, and interior composites under thermal variations to predict creep and stress cracking.
• Correlate & Validate: Model interior attachment methods and validate virtual models against component and sled test results.
• Optimize & Partner: Work with CAD and Design engineers to implement lightweighting and optimize rib patterns without compromising NVH or craftsmanship.
