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. 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
 
• Configure, integrate, validate and test CTC/TMS solutions, including ICONIS and/or EBI Screen platforms
• 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.
