Description

  • Define the simulation software toolchain and methodology used across the mechanical engineering team.
  • Lead a simulation-driven design process that informs early architectural trade-offs for the robot.
  • Develop company-wide standards for material models, boundary conditions, and safety factors for humanoid load cases.
  • Lead non-linear and dynamic finite element analysis for events such as robot falls and rapid limb acceleration.
  • Own fatigue life modeling and durability predictions for components subjected to millions of gait cycles.
  • Use topology optimization and generative design to reduce mass while maintaining stiffness-to-weight requirements.
  • Work with Hardware Integration and Test to design experiments that validate and calibrate simulation models.
  • Lead material characterization efforts for alloys, composites, and 3D-printed lattices to support accurate simulation inputs.
  • Mentor senior and staff engineers through deep-dive design reviews and technical problem-solving.

Requirements

  • 15+ years of experience in structural simulation and mechanical design.
  • Experience shipping complex, high-performance electromechanical products in robotics, aerospace, or automotive.
  • Expert-level proficiency with simulation tools such as Ansys, Abaqus, or SimCenter.
  • Deep knowledge of solid mechanics, vibration, shock, modal analysis, heat transfer, and multi-body dynamics.
  • PhD or MS in Mechanical Engineering, Aerospace Engineering, or a related field with a focus on Computational Mechanics.
  • Preferred experience with high-speed moving mechanisms or lightweighting structures for mobile platforms.
