Mechanical Engineer III – NVH, Simulation Materials

The Mechanical Engineer III is responsible for advanced noise, vibration, and fatigue testing to support the development of smoother, quieter, and more reliable products. This role utilizes state-of-the-art MTS hydraulic equipment and electro-dynamic shakers to simulate full-life structural validation. The incumbent will lead the transition toward data-driven design by integrating field data acquisition with advanced CAE simulation.

• Advanced Data Acquisition: Lead lab and field test projects using multi-channel instrumentation, including strain gauging, accelerometers, microphones, load cells, and CAN-bus.
• Field-to-Lab Replication: Perform Field Data Replication (FDR) Analysis to convert raw field data into accelerated laboratory test profiles (PSD/FDS).
• NVH & Sound Analysis: Execute Modal Analysis, Transfer Path Analysis (TPA), and Sound Quality Analysis to optimize the acoustic signature of Engines and Outdoor Power Equipment.
• Simulation Integration: Correlate physical test data with FEA and 1-D system modeling to predict fatigue life and resolve resonance issues.
• MTS Fatigue Testing: Lead structural validation of components and assemblies using MTS hydraulic equipment and specialized software.
• Regulatory Compliance: Manage EU Noise Compliance testing, ensuring all procedures meet the documentation standards required by our Notified Body
  .
• Warranty Reduction: Proactively identify failure modes in new battery and engine designs prior to field release through rigorous Reliability and Fatigue Damage Analysis.

• Education: Bachelor’s Degree in Mechanical Engineering or related field.
• Experience: Minimum 5-7 years of professional experience in NVH, Fatigue, or Structural Dynamics.
• Specialized Expertise:
• Proficiency in Siemens Sim Center Test Lab or equivalent DAQ systems.
• Hands‑on experience with MTS hydraulic controllers and Electro-Dynamic shakers.
• Understanding of and high-voltage battery and electric motor system characteristics.
• Advanced knowledge of Fatigue Damage and Reliability Analysis (Weibull).

The successful candidate will be expected to grow into Engineer IV responsibilities, including:

• Developing new-to-company advanced NVH test methods.
• Applying advanced CAE simulation to solve cross-platform system-level problems.
• Overseeing and mentoring lower-level technical support personnel and junior engineers.
