Vibroacoustic (noise) Engineer

Req ID:516773 

At Alstom, we understand transport networks and what moves people. From high-speed trains, metros, monorails, and trams, to turnkey systems, services, infrastructure, signalling and digital mobility, we offer our diverse customers the broadest portfolio in the industry. Every day, more than 80 000 colleagues lead the way to greener and smarter mobility worldwide, connecting cities as we reduce carbon and replace cars.

The Vibroacoustic engineer will act in the context of product developppement and R&D activities. 

In the context of Product Engineering development, the Vibroacoustic engineer will manage the noise and vibration performance in project/offer development through the application of internal procedures including Vibroacoustic management plan, standard Vibroacoustic simulation and measurements of Rolling Stock and Components.
In the context 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.

Main Responsibilities in the context of Project Engineering development

• To apply the Vibroacoustic Engineering Instructions and guidelines to perform the project/offers tasks
• To perform the Vibroacoustic analysis of tenders by comparison with referent solutions and previous projects
• To Prepare the Vibroacoustic specifications and Vibroacoustic Management Plan (VAMP) to be applied in projects
• To allocate the different noise sources and train assemblies through the use of ALSTOM standard methodologies for Rolling stock and for Componenrts
• To perform and postprocess standard Vibroacoustics tests and report to validate prediction models and type tests
• To perform standard Vibroacoustic simulations for exterior noise/interior noise and components
• To liaise with the Discipline Leader  to validate Management Plan, allocations and risks.
• To capture the Vibroacoustic REX of projects through the use of AT Vibroacoustic databases

Main Responsibilities in the context of R&D main activities

• To lead and manage R&D actions in the context of product improvement and/or methodologies for Vibroacoustics for Rolling Stock. This includes management of resources and budget respecting the quality, cost and delay of R&D deliverables.
• To develop innovative methodologies to be applied as a standard in the design process of rolling stock.

Educational requirement

• Engineering degree (BSc/MSc) or physicist with specialization in Vibroacoustic, acoustics, vibration, NVH

Experience

• More than 5 years of experience in a Vibroacoustic department in automotive/aeronautics/railway/building sector in the context of Product Developement and R&D assignments

Competencies & Skills 

• Vibroacoustic simulation with simplified methodologies (monopole type sources model)
• Vibroacoustic testing and postprocessing with multichannel systems (B&K Pulse, Siemens Test lab or similar) including noise & vibration measurements in operating conditions and Vibroacoustic transfer functions (mobility, pressure/force and Intensimetry measurements to characterize noise source)
• General project management : budget estimation and follow up, risk analysis and monitoring, milestone review with forecast and commitment.
• Optionnaly : 3D based simulation methodologies (FEM, BEM, ray tracing)
• Optionally : Experimental Modal analysis and Transfer Path Analysis, Sound quality analysis
• Matlab standard level is appreciated
• Good communication skills
• English fluent and strong multi-cultural working environement
• Willingness to travel for test

The position is located in St Ouen, ALSTOM headquarter next to Paris.

The applicant will join a team of 7 acoustic engineers and a network of more than 60 acoustic engineer worldwide.
