At Alstom, we build what millions depend on daily - rail transportation systems that can’t afford to fail. We’re more than 85 000 people worldwide creating the industry’s most diverse portfolio: high-speed trains, metros, trams, maintenance services and integrated systems.

More than a job: a mission

We’re looking for a Test Laboratory Technician to help validate and integrate the systems that keep rail networks running safely and reliably. This is hands-on work at the heart of innovation, where hardware, software, and signalling technologies come together in a critical testing environment.

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

• Perform hardware and software integration tests and technical verifications based on project requirements
• Prepare test procedures, scenarios and documentation for signalling laboratory activities
• Deploy and manage test environments to support integration, development and validation activities
• Support subsystem integration, third-party solutions and Factory Acceptance Tests (FAT)
• Ensure calibration, maintenance and compliance of laboratory equipment and measurement tools
• Analyse test results, prepare reports, troubleshoot issues and report failures or risks

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

What you bring

• Experience in testing, laboratory activities or technical validation environments
• Knowledge of hardware/software integration and measurement equipment
• Ability to analyse results, troubleshoot technical issues and maintain accurate documentation
• Awareness of EHS requirements and quality standards
• Strong organisational skills and attention to detail

How success is measured

• Timely execution of test programs in line with laboratory requirements
• Quality and accuracy of test reports and documentation
• Traceability and reliability of test conditions and measurements
• Contribution to laboratory efficiency, safety and continuous improvement

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.
