• Identify, report, and resolve system compatibility issues efficiently.
• Chair technical reviews/forums and resolve complex cross-functional issues.
• Develop methods and run technical studies into future technologies.
• Analyze standard cycles like emission tests and address related issues.

Your Profile

Essential skills/knowledge/experience:

• Experience in electrified propulsion system development (MHEV, PHEV).
• Strong background in Emissions/Gas Path/Aftertreatment.
• Experience in emissions or base engine engineering, including test bed experience.
• Knowledge of integration of core systems – Aftertreatment and Gas Path.
• Hands-on experience calibrating diesel engines for emissions on dyno with targets.
• Experience with emission calibration and regulations.
• Understanding of ICE engine gas path chemistry.
• Calibration knowledge and sensor control understanding.
• Experience with CAE on vehicle and propulsion systems, including Simulink modeling.
• Experience defining test cases and DoE for HIL, PIL, VIL, and vehicle environments.
