KOSMOS Tech Stack

Digital infrastructure platform for K-12 and higher education deployments

IT Services and IT Consulting Nantes, FRANCE 51–200 employees Founded 1998 Privately Held

Kosmos builds web portals, learning management systems, and e-portfolio solutions for schools and universities across Europe. The tech stack is mature and operationally heavy: PHP/Symfony backend, Kubernetes orchestration, Puppet/Ansible/ArgoCD for infrastructure-as-code, and a full CI/CD pipeline (Jenkins, Docker, Rancher). Active projects center on containerization, DevSecOps optimization, and AIOps integration—suggesting a shift from managing 1,200 servers through traditional infrastructure toward automated, predictable deployments. Engineering-led hiring (4 of 7 open roles) at mid-to-lead levels reflects ongoing infrastructure modernization rather than new product development.
