ATC System Designer

As a System Designer - Onboard Signaling, you will be at the core of the adaptation and specification process for Alstom's signaling systems (ERTMS/ETCS and legacy systems). Working on long-term projects, your role is to bridge the gap between customer needs and Alstom's existing system portfolio, ensuring the solution meets safety, reliability, and performance requirements. You'll analyse customer requirements, identify gaps with Alstom's generic solutions, write system specifications and contribute to configuring and testing the adapted solution. What You'll Do Requirements Analysis & System Adaptation

• Analyse customer documentation (e.g. specifications, functional requirements).

• Identify and formalize gaps between client needs and Alstom's generic solutions.

• Collaborate with the Development Center (DC) to determine how to bridge these gaps.

• Support the validation of proposed adaptations and their implementation by DC software teams.

• Ensure traceability through-out the formal documentation, up to the input requirements,

System Specification & Architecture

• Produce system and sub-system specifications, define architecture and interface requirements.

• Draft rules for data preparation (client-specific parameterization of equipment based on generic rules).

Integration & Design Testing

• Configure the equipment delivered from Generic Development Center in order to meet the project needs.

• Configure Test bench, integrate and Test the solution in lab (at design level),

• Participate eventually to investigations on trains when required,

• Participate to System tests (Track-On-board) of the complete solution within the infrastructure,

• Support test analysis and feedback to continuously improve the solution.

Cross-functional Collaboration

• Interact with other System Engineers and with other métier engineers to ensure the design fits into the intended architecture,

• Interact with RAM, Safety, Cybersecurity, Software, and V&V teams throughout the project.

• Act as a technical contact point for internal stakeholders and customers.

• Call, conduct, and participate to technical reviews (design reviews, document reviews)

Do you have experience in UML?, Do you have a Master's degree?, * Master's degree in Engineering (Electronics, Automation, Computer Science, Systems, etc.).

• First experience or strong interest in railway, aerospace, defense, or other regulated/safety-critical environments.

Key Skills

• Analytical mindset and ability to understand complex technical systems.

• Ability to interact with customers and interpret their needs into structured requirements.

• Knowledge of system design methodologies (UML, SysML) is a plus.

• Familiarity with change management, requirement management and traceability tools (e.g. ClearQuest, DOORS).

• Basic understanding of ERTMS/ETCS principles is a strong asset.

• A full proficient use of English and a good command of French are mandatory. Other languages would be assets (especially German).

• Rigorous and reliable / Eager to learn / Team spirit / Analytic mindset / Proactive / Good
