NVH Engineer

Job objective

Ensure that our vehicles fulfill the Mercedes-Benz standards regarding overall vehicle NVH, Sound & Aero performance for the Chinese customer.

Task description

Derive and implement China-specific requirements based on own experience and in cooperation with other RD departments

• Align and define NVH, sound & aero-acoustic performance targets and develop respective measures together within RD China and the global RD network
• Communicate and drive the implementation of the China-specific NVH, sound & aero-acoustic performance in vehicle projects (via Project groups, Commodity groups, Function integration groups). Provide input to functional and module strategies (China Requirement Working Groups, collaboration within global RD network).
• Prepare and align NVH, sound & aero-acoustic release documentation

Development and adjustment of NVH, sound & aero-acoustic function features to China-specific conditions and requirements

• Develop, adjust and validate NVH, sound & aero-acoustic testing procedures to meet major use cases in China in order to evaluate and release the NVH, sound & aero-acoustic performance.
• Identify most harming and customer-related parameters based on field research, customer observation and feedback.

Plan and conduct NVH, sound & aero-acoustic testing in China

• Plan and prepare the required vehicles, parts and resources.
• Conduct NVH, sound & aero-acoustic tests according to Mercedes-Benz standards and customer satisfaction.
• Coordinate tests on test benches and test facilities of GRC and 3rd parties.
• Organize evaluation drives and management drives.
• Create test reports and regularly present testing progress in relevant committees.

Issue finding, tracking and documentation

• Proper documentation of any issue findings in systems accordingly.
• Reproduce issues and support further analysis.
• Report the updated failure solving status at issue tracking platforms.

Education:

• University degree in
  acoustic/aero-acoustic engineering
  or mechanical/automotive engineering
  or sound/audio design
  or similar engineering qualification

Experience:

• Working experience at OEMs or suppliers for NVH, sound and aero-acoustic testing and development (including early development phases) preferred.

• Understanding of the market-specific preferences in terms of sound & vibration comfort including benchmarking.

• Familiarity with the China automotive supplier landscape and ecosystem.

• Familiarity with vehicle development process is an advantage (development phases, decision landscape).

• Familiarity with wind tunnel testing (aeroacoustics & aerodynamics) and/or sound design is helpful.

• Longer stay in Germany or abroad (business or education) is helpful.

• Specific Knowledge

• Solid knowledge of NVH, sound and aero-acoustic concepts.

• Profound knowledge in powertrain integration concepts (engine mounting, propeller shaft, mass damper, …).

• Familiarity with NVH material characteristics, component interactions, and functions.

• Sensitivity for issue detection, root cause analysis and system performance evaluation.

• Capability to evaluate test vehicles regarding NVH, sound and aero-acoustic behaviour (both in an objective and a subjective manner) under all conditions.

• Collect requirements and turn these requirements into specific concepts and target NVH descriptions to ensure the market-specific Mercedes-Benz sound character and vibroacoustic comfort. Drive the realization of these specifications.

• Support the technical powertrain integration process of market-specific requirements by initiating market-specific adaptations of the Mercedes-Benz user journey.

• Proficiency in using data acquisition systems and analysis software (e.g., LMS Test.Lab, Head Acoustics, PAK Artemis).

• Knowledge of advanced sound cancellation technique like Engine Order Cancellation (EOC).

• Develop and implement powertrain concepts for future vehicle platforms to meet stringent NVH targets.

• Collaborate with CAE simulation engineers (MBS, FEA, …) to design and optimize the vibroacoustic performance of the powertrain system and the vehicle.

• Perform vehicle-level NVH testing and analyze data to identify and resolve noise issues.

• Prepare the decision board meetings in interaction with module group speakers and component designers

• Integrate powertrain systems into vehicles, ensuring optimal NVH performance in alignment with the specbook performance targets and in exchange with emissions and fuel economy.

• Conduct vehicle-level testing and validation (on test benches and proving grounds) to identify and resolve integration issues.

• Collaborate with cross-functional teams (powertrain component, operating strategy, …) to design and develop the powertrain integration (engine mounting, propeller shaft, mass damper, …).

• Collaborate with simulation engineers to preselect testing variants or accelerate troubleshooting and root cause analysis.

• Experience with specific powertrain technologies (e.g., hybrid electric vehicles, battery electric vehicles, range extender vehicles, combustion engine vehicles).

• Other Knowledge

• Teamwork spirit with excellent communication, interpersonal and presentation skills.

• Initiative and ability to work independently and self-responsibly.

• Strong planning and organizational skills.

• Proficiency in MS Office tools like PowerPoint, Excel, and Word.

• Willingness to travel inside China and foreign countries.

• Fluent English and Chinese (oral, writing, listening and reading) is mandatory.

• German language knowledge is an advantage.

• Good driving skills.
