SNCF Connect & Tech Tech Stack

Sustainable mobility platform and SaaS solutions for travel and transport operators

SNCF Connect & Tech operates two parallel tech businesses: a direct-to-consumer travel platform and a B2B/B2G mobility software suite. The stack is polyglot (Java, Python, Node.js, React, Next.js, Flutter) with modern DevOps tooling (Kubernetes, Terraform, GitLab CI/CD), supporting both high-traffic web services and real-time journey optimization. Active hiring skews toward engineering and data roles, with no adopting or replacing signals in the latest cycle—suggesting the platform is in steady-state scaling mode rather than architectural pivot.
