About the role

Responsibilities

  • Own the mechanical technical specification, design, integration, and release for vehicle systems
  • Create CAD models, detailed drawings, and specifications for parts and assemblies (SolidWorks)
  • Drive product development cycles from concept to production, ensuring manufacturability and reliability
  • Troubleshoot issues, identify root causes, and design corrective/preventative solutions
  • Build, assemble, and operate test fixtures for mechanisms — including necessary coding & electrical setups
  • Characterize sensing systems (encoders, sensors) for bandwidth, latency, and other system parameters to support closed-loop motor control
  • Develop and execute test plans, analyze results, and drive design improvements based on data
  • Work closely with electrical, software, and external engineering partners to meet system-level goals for safety, performance, and cost
  • Serve as design release engineer for systems such as Electronics enclosures, harnesses, and sheet metal assemblies
  • Own subsystem Bills of Materials (BOM), assembly structures, and documentation within PLM systems (Arena)
  • Collaborate with program management to plan development schedules, builds, and resolve supply chain challenges

Qualifications

  • 4~8 years of experience in mechanical engineering, ideally in robotics, automotive, or other complex electromechanical systems
  • Proven record of taking products from concept through mass production
  • Strong proficiency with SolidWorks and 3D CAD modeling best practices
  • Understanding of GD&T and tolerance stack-ups for precision assemblies
  • Experience with PLM systems (Arena or similar)
  • Hands-on prototyping and test experience — comfortable assembling and debugging systems in a lab
  • Analysis skills for simple FMEA & Thermal simulations
  • Ability to collaborate across disciplines
  • Excellent problem-solving skills, with a data-driven approach to design decisions
