  • 5+ years of experience in engine testing, calibration, or powertrain development.
  • Hands-on experience with engine dynamometer operation and test cell environments.
  • Proficiency with DAQ systems (e.g., LabVIEW, ATI, ETAS, DEWESoft, or similar).
  • Strong understanding of combustion engines, thermodynamics, and control systems.
  • Experience calibrating engines for diesel, gasoline, or multi-fuel operation.
  • Ability to troubleshoot mechanical, electrical, and software issues in test environments.
  • Proficiency with data analysis tools (e.g., MATLAB, Python, Excel, or equivalent).
  • Excellent problem-solving skills and ability to work in a fast-paced, hands-on R&D environment.
Benefits & Perks
