Calibration Tuning Engineer

• Location: INDIANAPOLIS/COLUMBUS

• Openings: 1

The Calibration Tuning Engineer is responsible for calibrating, optimizing, and validating diesel engine control strategies to meet performance, fuel economy, emissions, and drivability targets.

The role demands strong understanding of the diesel engine features and simulation techniques.

To be successful in this role you will need the following:

· Lead calibration and tuning of diesel engine parameters including fuel injection timing and quantity, rail pressure, combustion phasing, air-path, EGR, boost control, and thermal management.

· Plan and execute engine-centric test cell activities for calibration, tuning, and validation.

· Create and Update Engine Feature Calibration Guide.

· Collaborate with feature owners to optimize Engine Feature Calibration.

· Troubleshoot engine performance, combustion, smoke, fuel consumption, and engine-out emissions issues.

· Diagnose control logic, calibration, and engine hardware issues observed during test cell operation.

· Use test cell data and Simulink model behavior to perform structured root cause analysis.

· Implement and validate corrective actions in control models and calibration datasets.

· Analyze steady-state, transient, combustion, and regulatory test cycles data and apply it to Simulation.

·

Strong understanding of Engine Controls in Simulink Models.

• Experience:

· Strong expertise in diesel engine calibration and combustion fundamentals.

· Strong experience executing and supporting engine test cell activities, including steady-state, transient, combustion, and emissions testing.

· Hands-on experience developing control system models in Simulink (must-have).

· Strong proficiency in MATLAB for engine and test data analysis (must-have).

· Proven troubleshooting capability across engine, controls, and calibration.

· Experience with calibration tools (ETAS INCA, ATI Vision, Vector CANape).

· Familiarity with engine test systems and DAQ

• Master’s degree (preferred) in Internal Combustion Engines, Automotive Engineering, Controls Engineering, or Powertrain Systems.
• 5–8 years of relevant experience in diesel engine calibration, tuning, and validation within engine test cell environments.
