More than a job: a mission

We’re looking for an Junior Telecomunications Engineer to help design, configure and validate the systems that enable safe and efficient rail operations. Working on cutting-edge control center technologies, you’ll contribute to critical infrastructure that keeps cities connected and moving.

• Generate configuration data and technical documentation for control center systems and integrations

• Participate in requirements elicitation and define internal and external system interfaces

• Support subsystem testing, system integration, commissioning activities and continuous improvement initiatives

You’ll work with sharp, committed teams across engineering, system engineering and project management - solving complex challenges that shape the future of mobility.

What you bring

• Technical degree or university degree in Computer Science, Telecommunications Engineering or a related field

• Experience in signalling projects, preferably within railway control center environments is a plus

• Fluent English communication skills

• Knowledge of SCADA systems, virtualization technologies, Windows Server and Linux environments, industrial communication protocols, networking, cybersecurity, databases and scripting/programming languages such as C#, VBS or PowerShell and Kubernetes

How success is measured

• Quality and reliability of configuration, integration and validation activities

• Timely delivery of engineering documentation and project milestones

• Effectiveness in supporting testing, commissioning and cross-functional collaboration

Alstom, a great place to grow

• Enjoy stability, challenges and a long-term career free from boring daily routines

• Collaborate with transverse teams and helpful colleagues

• Contribute to innovative projects

• Utilise our cooperative working environment

• Steer your career in whatever direction you choose across functions and countries

• Benefit from our investment in your development, through award-winning learning

• Benefit from a fair and dynamic reward package that recognises your performance and potential, plus comprehensive and competitive social coverage

Here, progress isn’t always easy - the scale is massive, the tasks are complex - but the impact is real. Because when the system runs, the train moves, and the city connects - that feeling stays with you. And the legacy lasts.
