Job Description

Title: Calibration Engine Performance
Location: Auburn Hills, MI.

Responsibilities:

Perform engine dynamometer calibration and development activities for gasoline engines.
Develop, optimize, and validate base engine calibration datasets to achieve performance, fuel economy, emissions, drivability, and robustness targets.
Calibrate airflow models, fuel flow models, torque models, calculated MAP models, catalyst and exhaust temperature models, and other combustion-related control algorithms.
Develop and optimize spark timing surfaces, minimum spark surfaces, knock control strategies, off-nominal spark adjustments, and cam phasing surfaces.
Calibrate maximum tip-in cam strategies, transient response models, and engine protection functions.
Support engine-out emissions calibration and cold-start emissions strategies.
Conduct combustion analysis, engine performance optimization, and emissions trade-off studies.
Utilize dyno automation and test scheduling systems to maximize test cell utilization.
Analyze large volumes of test data and implement calibration improvements.
Ensure calibration dataset management, version control, documentation, traceability, and release compliance.
Collaborate with controls, combustion, emissions, software, and validation teams.
Present technical findings and calibration results to internal and customer teams.

Requirements:

Minimum 10+ years of experience in engine dynamometer calibration and engine performance development.
Minimum 5+ years of gasoline engine calibration experience.
Strong understanding of combustion fundamentals, engine controls, calibration methodologies, and emissions regulations.
Hands-on experience with airflow and fuel flow modeling, spark and cam phasing calibration, knock calibration, calculated MAP and torque model development, catalyst and exhaust temperature modeling, cold-start emissions calibration, and drivability calibration.
Experience with standard dyno equipment, emissions measurement systems, CAS, and engine test laboratory instrumentation.
Proficiency in ETAS INCA, MATLAB/Simulink, Microsoft Excel, and Base Engine Calibration Toolkits/internal calibration analysis tools.
Strong knowledge of calibration dataset management, release processes, and change control practices.
Experience working with large datasets and data-driven problem-solving techniques.
Excellent communication and cross-functional collaboration skills.
