• Working closely with Vehicle Control, Safety, Configuration Management, Testing and Commissioning teams.
• Supporting system testing and validation, both in the laboratory and directly on the vehicle.
• Contributing to verification, safety and approval documentation throughout the project lifecycle.
• Supporting projects from the initial engineering phases through final system acceptance and approval.

What will help you succeed

We are looking for someone who combines strong engineering skills with an interest in railway signalling and safety-critical systems.

Ideally, you bring:

• A degree in Electrical Engineering, Automation, Telecommunications, Industrial Engineering or a related technical field.
• Professional experience in railway engineering, preferably related to signalling, train control, ATP, ETCS or other on-board systems.
• Experience with system integration and/or requirements engineering in complex technical environments.
• An understanding of railway safety, validation or certification processes.
• The ability to work effectively with multidisciplinary and international teams.
• Good communication skills and professional proficiency in English.

It would be a plus if you have

• Knowledge of ATP or ETCS on-board systems.
• Experience with ASFA.
• Familiarity with CENELEC standards and TSI requirements.
• Previous experience in high-speed rail or rolling stock projects.
• Experience working directly with customers, railway operators or technical suppliers.

What you can expect when joining us

You’ll join an international engineering environment where technology, safety and innovation come together to shape the future of mobility.

You’ll have the opportunity to work on high-speed rail projects, collaborate with multidisciplinary teams and develop your expertise in some of the most advanced on-board railway systems.

We offer a hybrid working environment that combines collaboration in the office with the flexibility of remote work, together with opportunities for continuous learning and professional development.
