Senior Calibration Engineer

Responsibilities

• 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.
• Support aftertreatment calibration (DOC, DPF, SCR) with primary ownership on engine-out emissions.
• Plan and execute engine-centric test cell activities for calibration, tuning, and validation.
• Support Controls Engineer and Test Cell Technician to instrument engines and combustion measurement systems (pressure transducers, air/fuel flow, emissions).
• 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.
• Execute steady-state, transient, combustion, and regulatory test cycles.
• 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 engine test cell experience.
• 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

Qualifications

• 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.
