Vibroacoustic Engineer

We are seeking a skilled Vibroacoustic Engineer to join our team at Alstom, a global leader in transportation systems. In this role, you will participate in project development through the application of internal procedures, including Vibroacoustic management of projects, standard Vibroacoustic simulation, and measurements of Rolling Stock and Components.

As a Vibroacoustic Engineer, you will be responsible for the development of methodologies and technologies related to Vibroacoustics of Rolling Stock and Components. Your tasks will include:

• Applying Vibroacoustic Engineering Instructions and guidelines to perform project and offer tasks
• Performing Vibroacoustic analysis of tenders by comparison with referent solutions and previous projects
• Preparing Vibroacoustic specifications and Vibroacoustic Management Plan (VAMP) to be applied in projects
• Choosing the most efficient way to perform the allocation (experimental/numerical), verification, and validation during tender and project phase
• Allocating different noise sources and train assemblies through the use of AT standard methodologies
• Performing standard Vibroacoustics tests, postprocessing data, and reporting to validate prediction models and type tests
• Performing standard Vibroacoustic simulations for exterior noise and interior noise using inhouse developed tools
• Liaising with the Acoustic Chief Engineer to validate Management Plan, allocations, and risks
• Liaising with experts in key domains to obtain necessary data to perform the allocation
• Liaising with acoustic engineers in other sites and using AT Vibroacoustic databases to obtain necessary REX to perform the allocations
• Capturing Vibroacoustic REX of projects through the use of AT Vibroacoustic databases

In the context of Product Engineering development, a Vibroacoustic Engineer will participate in project/offer development through the application of internal procedures. In case of assignment to R&D tasks, he will be in charge of the development of methodologies and technologies related to Vibroacoustics of Rolling Stock and Components.
