• 3–6 years of NVH/VD validation experience.
• Hands-on with instrumentation and data acquisition systems.
• Proficiency in NVH signal analysis (FFT, Order tracking, Spectrogram).
• Ability to interpret frequency peaks and excitation orders.
• Strong collaboration with other departments and track management.

Responsibilities

• Execute vehicle-level NVH and VD validation across conditions.
• Conduct BSR Testing and score generation.
• Benchmark Vehicle Attributes: Power Train Noise, Road Noise, Wind Noise, and Idle Boom Noise; Ride and Handling.
• Set up instrumentation and ensure correct sensor placement.
• Produce data-driven inputs for design improvements (BIW, mounts, trims).
• Prepare objective test datasets and subjective evaluation reports.

Deputy Manager - Vehicle Attributes

Responsibilities & Key Deliverables

Roles & Responsibilities Execute vehicle-level NVH & VD validation, subjective and Objective to ensure achievement of defined noise, vibration, and harshness and steering, brakes, handling and ride targets across all operating conditions. Should be able to conduct BSR Testing and score generation. Acoustic and vibration data along with subjective sound quality assessments to support vehicle refinement. Identify NVH & VD performance gaps early and provide data-driven inputs for design improvements (BIW, powertrain mounts, trims, sealing, etc.). Benchmarking of Vehicle Attributes viz. Power Train Noise, Road Noise, Wind Noise and Idle Boom Noise and Ride, Handling, Braking, Steering and Stability. Need to establish and maintain good inter-personal and inter-departmental relations and with the track management authorities.

Key Deliverables
