YourLiebherrCareer: Engineer - Quality (BU-Drives)

Roles & Responsibilities:

• Assembly Quality – Slewing Drive:

• 
  
  
  
  • Ensure 100% compliance to Assembly Work Instructions (WI), torque charts, tightening sequences, and critical-to-quality (CTQ) parameters.
  
  
  • Conduct and monitor in-process inspections for sub-assemblies and final assemblies (slewing drive gearboxes, motors, seals, bearings, housings).
  
  
  • Verify bearing preload, backlash, endplay, gear meshing, shim thickness, and lubrication levels as per specification.
  
  
  • Develop and maintain control plans, inspection standards, and check sheets for slewing drive assembly.
  
  
  • Ensure availability, calibration, and correct usage of torque wrenches, dial gauges, feeler gauges, micrometers, and other critical gauges.
  
  
  • Support problem-solving (5 Why, Ishikawa, 8D) for assembly defects, leakages, fitment issues, noise/vibration issues, or test failures.
  
  
  • Review first-off and special process validation for new assembly setups or engineering changes.
  
  
  
  

• Painting Quality Assurance:

• 
  
  
  
  • Inspect surface preparation quality: blasting profile, roughness (Ra), cleanliness (Sa), welding spatter removal, burr removal.
  
  
  • Verify DFT (Dry Film Thickness), paint adhesion, hardness, gloss, color shade, curing time, contamination, and rust prevention.
  
  
  • Ensure correct usage of paint material, hardener ratios, pot life, environmental conditions (humidity/temperature).
  
  
  • Approve paint process parameters as per paint system requirements (primer, intermediate, topcoat).
  
  
  • Conduct visual inspection as per ISO 12944 / company paint standards.
  
  
  • Support paint booth audits, paint consumable control, and rework reduction.
  
  
  • Handle painting NCRs, shade deviations, pinholes, orange peel, under-film corrosion, and ensure timely corrective actions.

• 
  
  
  
  • Ensure functional test compliance for slewing drives:
  
  
  • Noise & vibration levels
  
  
  • Torque test
  
  
  • Leak test / pressure retention
  
  
  • Operating smoothness and rotational efforts
  
  
  • Support FAT/Pre-dispatch inspection with customer or internal project team.
  
  
  • Validate test records and ensure full traceability against serial number and batch code.
    
  
  
  
  

• Dispatch Quality & Documentation:

• 
  
  
  
  • Ensure 100% inspection of finished goods before dispatch.
  
  
  • Verify completeness of:
  
  
  
  

•

    • Torque records
    
    
    
    
  
  
  
  

• 
  
  
  
  • Ensure export packing meets customer and internal standards (VCI protection, wooden box spec, moisture control, cushioning, export marking).
  
  
  • Conduct final visual audits, dimensional checks, and cleanliness verification before packing.
  
  
  • Coordinate with stores and dispatch to ensure zero damage during internal handling or loading.
  
  
  
  


• Quality System, NCR Handling & Continuous Improvement:

• 
  
  
  
  • Lead or support NCR investigation, root cause analysis and CAPA actions for
  
  
  • assembly/painting/dispatch issues.
  
  
  • Ensure strict compliance to ISO 9001, ISO 14001, safety rules, and internal QMS.
