Groupe SNCF operates France's largest rail network across five business units: passenger services, regional transport, long-distance travel, logistics/freight, and station operations. The tech stack reveals a hybrid modernization path—legacy systems (C++, Windows, ClearCase, Visual Basic) running core rail operations alongside active adoption of Power Platform, AWS, and Azure, plus emerging use of Mistral for AI workloads. The engineering-heavy hiring profile (215 roles) is concentrated on infrastructure renewal and ERTMS deployment, while pain points cluster around modernizing aging rail infrastructure and ensuring safety compliance—a maturity challenge for operators managing critical national transport.
