Req ID: At Alstom, we build what millions depend on daily - rail transportation systems that can't afford to fail.

We're more than people worldwide creating the industry's most diverse portfolio: high-speed trains, metros, trams, maintenance services and integrated systems.

More than a job: a missionWe're looking for a Computer Vision Engineer to help develop TrainScanner, one of the most advanced railway inspection platforms based on 3D scanning, computer vision and automated analysis technologies.

You will contribute to solutions that improve railway safety and maintenance through accurate digital reconstruction and intelligent inspection algorithms.

You'll work alongside people who show up with ownership, passion, and dedication - because they know what's at stake: the journey home.

Your role, your impact

Define and select cameras, optics and lighting systems for railway inspection applications

Develop calibration strategies and optimize image acquisition processes

Process and reconstruct data from 3D cameras, laser sensors and other scanning technologies

Design and develop computer vision algorithms for automated inspection and measurement systems

Create solutions for point cloud filtering, segmentation, cleaning and 3D model analysis

Collaborate with multidisciplinary teams to deploy innovative inspection architectures in industrial environmentsYou'll work with sharp, committed teams across engineering, software, electronics, mechanical design and railway inspection - solving complex challenges that shape the future of mobility.
