About the Job

Requirements

  • A master's degree in Engineering or higher is required.
  • At least 7 years of finite element analysis experience, including applied solid mechanics and numerical methods, using Altair products for preprocessing (HyperMesh, SimLab, OptiStruct), Dassault products for stress and fatigue solutions (Abaqus, fe-safe), and N-code.
  • A deep understanding of mechanics of materials, statics, dynamics, fatigue, and sealing is required.
  • Knowledge of computer-aided design is required; CATIA is preferred.
  • Expertise in 2D and 3D modeling, sub-modeling, sub-structures, and hyperelastic sealing modeling is required.
  • Expertise in scripting, coding, and automation with Python or C is required.
  • The candidate must be able to methodically root-cause issues using a first-principles approach.
  • The candidate must be able to make data-driven decisions and demonstrate analytical skills.
  • The candidate must be able to work collaboratively with and influence cross-functional departments internally and externally.
  • The candidate must understand mechanical engineering theory, including static and dynamic analysis, fatigue, and vibration analysis.

Responsibilities

  • Analytically validate components and system-level assemblies against requirements using finite element analysis during the design phase.
  • Perform topology optimization by blending strength and noise, vibration, and harshness objectives to identify necessary ribbing structures within available package space and meet structural and noise, vibration, and harshness constraints.
  • Perform linear and nonlinear static analyses for complete drive unit systems.
  • Perform noise, vibration, and harshness analyses, including modal, frequency-response, and mount-mobility analyses.
  • Perform fatigue analyses, capturing pre-stress from assembly loads and scaling or superposing functional loads to a duty cycle.
  • Perform sealing analyses, including component hyperelastic analysis, and evaluate system-level seal performance.
  • Apply an understanding of loads and boundary conditions to drive unit components and systems to capture realistic interactions.
  • Apply topology optimization expertise to blend multiple objectives and constraints.
  • Apply knowledge of material strength and fatigue, including the effects of manufacturing on material performance.
  • Support and participate in design reviews by preparing and presenting scorecards or reports that highlight analysis results and recommendations or solutions to resolve issues.
  • Root-cause launch and prototype issues using data-driven methods.

Desired Qualifications

  • Knowledge of CATIA is preferred.

About the Company

Rivian

Makes electric pickups, SUVs and delivery vans

Rivian designs and builds electric pickup trucks, SUVs, and delivery vans, pairing off-road ability with electronics and software it develops itself. In 2021, its R1T became the first fully electric pickup truck on the US consumer market, ahead of larger rivals such as Ford and Tesla. It makes the R1T pickup, the R1S and R2 SUVs, and commercial vans in Normal, Illinois, and sells them directly online and in its own stores rather than through dealers. Its vehicles run on Rivian's own software, which gains features through updates sent over the internet, and most revenue comes from vehicle sales, with service and optional software adding more. Rivian was founded in 2009 and is based in Irvine, California.
