Location: San Francisco
Workplace: Hybrid
Employment Type: Full time
Job Function: Sales
Seniority: Sr. Manager level

Key Responsibilities

  • •Own advanced simulation of the electro-mechanical locking ecosystem, using Multibody Dynamics and non-linear transient analysis to validate extreme impacts and intentional vandalism.
  • •Drive vehicle frame and weldment optimization early in the design cycle with fatigue and weldment simulations to reduce conservative margins and manufacturing cost/weight.
  • •Lead high-fidelity explicit dynamics simulations for severe, short-duration impact events and perform random vibration analysis to mirror aggressive road testing.
  • •Partner with Reliability to correlate analytical CAE models with lab tests and actual field failure data, improving predictive engineering capabilities.
  • •Collaborate globally with internal teams and suppliers, supporting vehicle builds at Asian contract manufacturers and coordinating prototyping/testing in the San Francisco lab.
Travel: Medium travel
