Decasoft is a 20-year-old Paris-based software services firm with dual offices in Paris and Toulouse, transitioning from traditional application development into infrastructure automation and ML production. The tech stack is heavily enterprise-oriented (Java, Spring Boot, .NET, Kubernetes, Docker, Jenkins) with active work on event-driven architecture and LLM integration. The engineering-dominant hiring mix (14 engineers across senior and lead levels, plus 2 data roles) and project portfolio—industrializing ML production, automating workflows, and building infrastructure roadmaps—signal a shift from body-shop services toward in-house platform and transformation delivery.
