With over 27,000+ associates, it's the largest software development center of Bosch, outside Germany, indicating that it is the Technology Powerhouse of Bosch in India with a global footprint and presence in the US, Europe and the Asia Pacific region.

About the Role

Drivability Calibration Engineer is responsible for developing, tuning, and validating engine and vehicle control strategies to ensure smooth, responsive, and comfortable vehicle performance across all operating conditions (start, idle, transient, part-load, and full-load).

Key Responsibilities

1. Drivability Calibration Development

Develop and optimize drivability calibration for:

Gasoline engines (MPFI, TGDI)

Diesel engines (CRDi systems)

Calibrate:

Tip-in / Tip-out response

Torque structure and request coordination

Transient fuel, rail pressure, and boost control

Injection strategies (Diesel: pilot, main, post injections)

Idle control, cold start, and warm-up behavior

Tune pedal maps for different drive modes (Eco/Normal/Sport)

2. Torque & System Coordination

Ensure robust torque arbitration between:

EMS and TCU (MT/AMT/AT/DCT)

Optimize:

Shift quality (torque reduction, ramp-in/out)

Clutch engagement behavior

Coordinate with:

Air path (EGR, VGT, throttle)

Aftertreatment systems (DOC, DPF, SCR impact on drivability)

3. Validation & Testing

Perform subjective and objective drivability evaluations

Define and track KPIs:

Surge / Bucking index

Hesitation / turbo lag

Tip-in delay & torque hole

Low-speed behavior (creep, crawl)

Diesel-specific NVH (combustion noise, torque oscillations)

Plan and execute:

City / highway / hill / hot & cold condition tests

Use tools:

ETAS INCA / CANape / AVL Drive

Data acquisition systems (V-Box, iCDM/vCDM)

4. Issue Analysis & Debugging

Identify and resolve P0/P1 drivability issues

Perform root cause analysis using:

Measurement data

System interaction understanding

Conduct:

On-road calibration refinement

• Rapid issue resolution during test trips

5. Integration & Cross-functional Coordination

Work with:

Combustion & Base Calibration Teams

Transmission & Hybrid Control Teams

OBD and Emissions Teams

Ensure drivability trade-off alignment with:

Emissions (BS6/Euro norms)

Fuel efficiency targets

NVH requirements
