Sr. CAE Engineer

About the role

Rivian is seeking a Staff CAE Engineering to guide and shape drive unit designs via FEA. The role involves working cross-functionally with various teams to ensure successful product launches.

Responsibilities

• Work upfront during the design phase to analytically validate via FEA components and system level assemblies against requirements.
• Topology Optimization blending strength/NVH objectives to help identify necessary ribbing structure within the available package space to meet structural and NVH constraints.
• Linear/Nonlinear static analyses for complete Drive Unit systems
• NVH analyses (modal, frequency response, mount mobility)
• Fatigue analyses with knowledge on how to capture pre-stress from assembly loads and scale/superpose function loads to a duty cycle.
• Sealing analyses with expertise in component hyper-elastic analysis and leading to the system level seal performance of the system.
• Proficiency with understanding loads and their applications on various drive unit components/systems.
• Proficiency with understanding boundary conditions and their application on various drive unit components/systems to capture realistic interactions.
• In depth understanding of topology optimization with the capability to blend multiple objectives/constraints.
• In depth understanding of material strength/fatigue, effect of manufacturing on material performance.
• Support and participate in Design Reviews by preparing and presenting score cards/reports to highlight analysis results and recommendations/solutions to resolve issues.
• Root Cause launch/prototype issues in a data driven way.

Qualifications

• MS in Engineering or higher.
• 7-10 years + Finite Element Analysis proficiency with Applied Solid Mechanics and Numerical Methods, experience using Altair products for pre-processing (Hypermesh, Simlab, Optistruct), Dassault products for stress/fatigue solutions (Abaqus, Fe-Safe), and N-code.
• Deep understanding of mechanics of materials, statics, dynamics, fatigue and sealing.
• CAD knowledge – CATIA preferred.
• Expertise in 2D and 3D modeling, sub-modeling, sub-structures and sealing modeling expertise (Hyperelastic).
• Expertise in scripting/coding and automation with Python / C+
• Passion for problem solving with the ability to methodically root cause issues by following first principles approach.
• Able to make data driven decisions and demonstrate good analytical skills.
• Excellent interpersonal skills with the ability to collaboratively work with and influence cross-functional departments both internally and externally.
• Energy & curiosity to make things happen, seek out solutions and represent a world class brand.
• Understanding of theory in a range of mechanical engineering subjects, including static dynamic, fatigue, vibrations analyses.
