NVH & Acoustics Engineer (Engine Systems)

Key Responsibilities:

• Develop, validate, and correlate GT-Power acoustic models for exhaust and aftertreatment systems.
• Collaborate with the EBU SPA team to calibrate and tune ATS acoustic models.
• Develop CFD-based aeroacoustics prediction methodologies for exhaust and aftertreatment applications.
• Perform engine noise source characterization, acoustic mapping, and P3 analysis.
• Conduct SPL, FFT, order analysis, and pressure pulsation studies.
• Correlate simulation predictions with engine dynamometer, component, and vehicle-level test data.
• Support NVH root-cause investigations and provide simulation-driven engineering recommendations.

Skills and Experience Required:

• 3 to 6 years of experience in NVH, acoustics, aeroacoustics, engine testing, or simulation-led product development.
• Experience with heavy-duty diesel or natural gas engines.
• Familiarity with Source-Path-Receiver methodologies, Transfer Path Analysis (TPA), and acoustic target decomposition.
• GT-Power / GT-SUITE Acoustics
• Engine Testing and Engine NVH Testing
• ATS Acoustic Modelling and Correlation
• CFD & Aeroacoustics (STAR-CCM+ or equivalent)
• Engine Noise Source Characterization
• SPL Test-to-Simulation Correlation
• FFT, Order Analysis, and Pressure Pulsation Analysis
• MATLAB and/or Python for acoustic data analysis
