  • Analysis and Validation: Perform structural, kinematic, and tolerance analysis to ensure safety, reliability, and performance across varied payloads and use conditions. 
  • Prototyping and Testing: Build and evaluate prototypes, debug mechanical issues from field escalations, and lead design iterations based on test data and operational feedback. 
  • Manufacturing Handoff: Ensure DFM/DFA compliance, support vendor communication for part fabrication, and participate in pre-production builds. 

Minimum Qualifications 

  • Proven Technical Foundation: Demonstrated success in delivering high-quality mechanical designs — either through a strong academic program or impactful work at a robotics, automotive, or automation company. 
  • Motion Subsystem Experience: 10 years designing mechanical components such as drivetrain assemblies, lift mechanisms, or mobile robot frames. 
  • CAD Mastery: Expertise in 3D modeling and detailed 2D drawings using SolidWorks or equivalent, including GD&T application. 
  • Design for the Real World: Experience with DFM/DFA, mechanical tolerancing, and material selection for production-quality parts. 
  • Hands-On Debugging: Ability to prototype, test, and troubleshoot issues in real hardware — especially in deployed or customer-facing systems. 
  • Good command of the English language and ability to communicate with local suppliers in Japanese. 
  • Competitive salary and benefits package. 
  • Opportunity to work on cutting-edge robotics technologies. 
  • Collaborative and innovative work environment.
