Deep into the project:

The Diabolocom Hybrid Cloud is composed of on-premise infrastructure distributed amongst 5 dedicated collocations around France and Germany and public clouds (AWS / GCP / OVH).

Offering solutions with a high level of security and availability, and certified environments, notably PCI-DSS and HDS (health data), ops team is responsible for making sure everything runs smoothly, in a scalable and secure way, 24/24, 7/7.

In a context of strong development, Diabolocom is working on the evolution of its infrastructure, from proxmox-based infrastructure using VMs deployed via Ansible, to a Kubernetes oriented architecture deploying applications with ArgoCD. We are looking for people able to maintain legacy infra while it’s being migrated, but also able to architect and build the future with new tools and state-of-the-art technologies and methodologies.

Our legacy infrastructure still has some interesting features, including full IaC management. Among other things, our servers and VM are booted over PXE on self-generated, fully IaC images generated with our Ansible playbooks.
