You will be responsible for the end-to-end mechanical design of gears, shafts, housings, and complete differential assemblies. Collaboration is key—you’ll work closely with validation, process, and system engineering teams to ensure that designs meet performance, manufacturability, and cost targets.

Your responsibilities will be to:

  • Perform macro and micro geometry design of gears and gear systems

  • Optimize gear tooth root geometry using FEA and fatigue models

  • Design and 3D model mechanical components: gears, shafts, washers, housings, etc.

  • Create technical drawings and tolerance stacks according to automotive standards

  • Support DFMEA, tolerance analysis, and design reviews

  • Interface with internal prototyping and validation teams

  • Collaborate with manufacturing engineers to ensure process-feasible designs

  • Contribute to documentation and design release activities

:

  • Bachelor’s or Master’s degree in Mechanical Engineering or related field

  • Ideally more than 2 years of experience in mechanical design, ideally in powertrain or gear applications

  • Prior exposure to automotive environments preferred

  • Proficient in 3D CAD (e.g. Creo, CATIA, or similar) and GD&T

  • Basic understanding of gear design principles (macro/micro geometry, contact patterns) and familiar with gear design tools (KISSsoft, Masta, or similar)

  • Basic understanding of gear manufacturing processes

  • Structured working approach and ability to work in interdisciplinary teams

  • Fluency in English is mandatory. German language proficiency is desirable, while fluency in Chinese would be a significant asset

  • Strong problem-solving and communication skills
