IT Services and IT Consulting Versailles, Ile-de-France 501–1,000 employees Founded 2014 Partnership

LR Technologies is a mid-sized French engineering consultancy (501–1,000 employees) serving nuclear, aerospace, railway, and financial services. The tech stack reveals a hybrid practice: CAD-heavy design work (Revit, AutoCAD, Solidworks) paired with backend infrastructure (Java, Spring Boot, PostgreSQL, Kubernetes, AWS). Active projects span microservices refactoring, payment validation, and electronic invoicing—suggesting a shift toward modernizing legacy systems in regulated industries. Hiring remains engineering-dominated (70% of open roles), with senior and mid-level seniority ratios indicating mature project delivery rather than startup-scale growth.
