Job Description

Responsibilities & Key Deliverables
As a Lead Engineer - NVH at Mahindra & Mahindra Ltd, you will play a critical role in enhancing the acoustic performance and noise vibration harshness (NVH) characteristics of our automotive products. Your responsibilities will include:

• Developing a comprehensive understanding of automotive NVH, including motorized noises, product development aspects, and the factors affecting BSR (Buzz, Squeak, Rattle).
• Conducting detailed analyses to identify BSR noises generated from various vehicle systems during driving tests or through component-level testing on a BSR shaker.
• Implementing both quasi-static tests and solidity tests to facilitate the subjective identification and localization of BSR issues.
• Setting up effective systems for vibration and noise measurement, which includes data acquisition and thorough data post-processing across various scenarios such as RLDA (Road Load Data Acquisition), relative motion analysis, and overall NVH measurements.
• Designing and developing fixtures to support component-level testing for diverse vehicle elements including cockpits, doors, and seats under BSR conditions.
• Identifying and diagnosing BSR noises within vehicle interior systems, capturing detailed reports, and coordinating with relevant stakeholders for timely resolutions.
• Utilising advanced acoustic holography techniques to locate and document noise-prone areas effectively.
• Providing insights and practical expertise in addressing squeak and rattle phenomena, including understanding occurrences and root causes at various stages of the product lifecycle.
• Maintaining a fundamental knowledge of automotive systems, including understanding the different types of design, manufacturing and assembly processes, as well as materials used in the production of trims, body-in-white (BIW), and glass seal mechanisms.
• Gaining insights into sound quality dynamics from all motorized noise sources, such as actuators and small fans, which will augment your contributions to overall product refinement.

Experience
The ideal candidate for this position should possess:

• A minimum of 6-8 years of proven experience in the field of NVH and BSR testing, exhibiting advanced understanding and practical know-how.
• Proficiency with industry-standard testing software including LMS Siemens, Head Acoustics, and BSR Suite by MB Dynamics, bolstered by excellent skills in fixture design, NVH basics, and BSR fundamentals.
• Knowledge of non-stationary signal analysis and processing techniques is essential. Familiarity with DSP (Digital Signal Processing) and acoustic holography techniques will be considered valuable assets.

Industry Preferred
Relevant industry experience is crucial to the role:

• Experience in the automotive sector is preferred, as this field demands a keen understanding of the noise characteristics specific to vehicles and their components.

Qualifications
Candidates should hold the following qualifications:

• A Bachelor of Engineering (BE) degree in Mechanical or Automotive Engineering, or a Master of Technology (MTech) degree in a related mechanical discipline.
• Your academic background should be complemented by practical experience and a deep-seated passion for automotive engineering and development.

General Requirements
General requirements for this role include:

• Strong presentation skills and the capability to generate thorough documentation and reports that effectively communicate findings and recommendations.
• Competency in driving to facilitate the excitation of issues on vehicles during end-of-line checks or field assessments.
• A proactive approach to problem-solving and a commitment to continuous improvement in all tasks undertaken.
