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.
• Familiarity with the China automotive supplier landscape and ecosystem.
• Understanding of the market-specific preferences in terms of sound & vibration comfort.
• Familiarity with sound isolation component development coordination.
• 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, pass-by-noise, sound and aero-acoustic concepts.
• Profound knowledge in designing sound isolation concepts and developing sound isolation packages.
• Familiarity with NVH material characteristics, component interactions, and functions.
• Experience with NVH & wind tunnel measurement & analysis tools.
• 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 sound descriptions to ensure the market-specific Mercedes-Benz sound character. Drive the realization of these specifications.
• Support the technical and creative sound isolation process of market-specific requirements by initiating market-specific adaptations of the Mercedes-Benz user journey.
• Experience with acoustic measurement techniques (e.g., sound intensity, sound pressure level, reciprocal measurements, beam forming, …).
• Proficiency in using data acquisition systems and analysis software (e.g., LMS Test.Lab, Head Acoustics).
• Ability to conduct vehicle-level NVH testing and analyze test data.
• Understanding the material release and manufacturing processes relevant to sound isolation components.
• Experience with specific vehicle platforms or systems (e.g., ICE, PHEV, REEV, BEV, powertrain NVH).
• Knowledge of advanced sound isolation techniques (e.g., active noise control, metamaterials) and sound cancellation techniques: RNC (Road Noise Cancellation), EoC (Engine order Cancellation).
• Develop and implement innovative sound isolation concepts for future vehicle platforms to meet stringent NVH targets.
• Collaborate with CAE simulation engineers (SEA, …) to design and optimize the acoustic performance of vehicle components and systems.
• Perform vehicle-level NVH testing and analyze data to identify and resolve noise issues.
• Collaborate with cross-functional teams to integrate sound isolation solutions into vehicle designs.
• Prepare the decision board meetings in interaction with module group speakers and component designers
• Using PDM systems to document the geometry changes, processes
