Information Technology & Services Lyon, Auvergne-Rhône-Alpes 11–50 employees Founded 2013 Privately Held

O2MAX is a 40-person systems integrator based in Lyon with 11+ years of delivery experience across Java, Angular, cloud platforms, and data engineering. The tech stack reveals a Microsoft-centric internal environment (365, Teams, Intune) paired with Java/Spring for client work and Kubernetes-based CI/CD orchestration—a pattern common in French consulting shops serving both legacy and cloud-native clients. Active hiring skews heavily toward senior engineers (22 of 33 open roles), suggesting client-side scale challenges rather than bench staffing.
