CORYS Tech Stack

Dynamic simulators for rail, power, and process operator training

Software Development GRENOBLE cedex 1 201–500 employees Founded 1989 Privately Held

CORYS builds physics-based training simulators for critical infrastructure operators, with over 3,700 systems deployed across rail, power, and process industries. The tech stack is heavily graphics-oriented (Unreal Engine 5, C++, Blender, Substance Painter, SolidWorks) paired with DevOps tooling (Jenkins, GitLab, Grafana), reflecting a company transitioning from traditional engineering simulation toward photorealistic 3D environments—projects include railway world creation and sensor suite integration, while pain points cluster around 3D production chain overhauls and CI/CD optimization. Hiring is concentrated in France with a steep intern-to-senior ratio, signaling either scaling challenges or project-based contracting patterns.
