French IT services firm modernizing legacy systems and cloud infrastructure

IT Services and IT Consulting Lyon, Auvergne-Rhône-Alpes 51–200 employees Privately Held

GUARANÍ is a 14-year-old digital services firm (ESN) operating across 7 French cities with ~400 staff, focused on system modernization and enterprise migrations. The tech stack is heavily Microsoft-centric (Azure DevOps, C#, .NET, SQL Server, Dynamics 365) alongside Oracle and Salesforce, with growing adoption of containerization (Docker, Kubernetes) and cloud platforms (Azure, AWS, GCP) — a pattern consistent with clients migrating monolithic on-premises systems. Current hiring (18 engineering roles, mostly mid/senior level) is concentrated in backend and platform work, while active projects cluster around Salesforce migrations and legacy system urbanization, suggesting GUARANÍ is scaling delivery capacity for large infrastructure overhauls.
