Job description

At Tata Technologies we make product development dreams a reality by designing, engineering, and validating the products of tomorrow for the world’s leading manufacturers. Due to our continued growth, we are now recruiting for a below position

Location: Columbus, IN

Duration: Full Time

For the below position:

The Engine Tuning Engineer is responsible for calibrating, optimizing, and validating diesel engine and aftertreatment control strategies to meet performance, fuel economy, emissions, and drivability targets. The role demands strong hands‑on test cell experience and proactive troubleshooting of engine, aftertreatment, and test system issues throughout development and validation programs.

RESPONSIBILITIES

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.
• 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 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 & Education:

• 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
