Job description

The Factory Design & Simulation team at Rivian plays a crucial role in redefining automotive manufacturing by optimizing value streams for the production of electric vehicles. This position involves using discrete event simulation to guide factory design from concept to operation, ensuring that designs meet production goals. Candidates will collaborate with various teams to establish throughput architecture and identify bottlenecks during production. The role requires a strong understanding of manufacturing engineering principles and a focus on design optimization.

Requirements

  • Bachelor's degree in Industrial Engineering, Mechanical/Manufacturing Engineering, or Computer Science
  • 5+ years of experience in industrial or manufacturing engineering with a focus on discrete event simulation
  • Extremely proficient with discrete-event simulation tools
  • Familiarity with creating new features and modules within discrete event simulation platforms using FlexScript, Simtalk, C++, and/or Python
  • Knowledge of statistics, uncertainty, and sensitivity analysis
  • Strong analytical and organizational skills
  • Effective written and verbal communication at all organizational levels

Responsibilities

  • Build discrete event simulation models for various parts of the manufacturing or logistic process
  • Manage multiple integrators and integrate their deliverables into shop and factory models
  • Develop decision-making frameworks with quantifiable tradeoffs for the entire factory or individual manufacturing processes
  • Optimize plant layouts by analyzing throughput capabilities, bottlenecks, buffer sizing, and material routing
  • Collaborate with the Automation & Controls team to validate models and suggest improvements
  • Develop and sustain digital twin models to effectively test and validate the designs of manufacturing systems
  • Co-develop standards for discrete event simulation models and create a library of simulation assets

Benefits

  • Employees at Rivian are often offered comprehensive health, dental, and vision insurance, a 401(k) with company match, ESPP and potential RSU grants, performance bonuses, and generous time off including paid parental and sick leave.
