About you

We offer you to join our Ops team in order to cover regular operations and architecture, at the heart of the Diabolocom service. Ops team participates in the deployment and operational maintenance of our SaaS platforms, on a Hybrid Cloud basis.

The Diabolocom Hybrid Cloud is composed of on-premise infrastructure distributed amongst 5 dedicated colocations around Paris 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.

At Diabolocom, you will:

Co-architect new infrastructure to contribute to its evolution and migration to kubernetes

Develop PoCs to test and validate new decisions

Be in charge of the infrastructure, both legacy and new one, and its global vision

Be interested in the evolution of standards to advise and propose upgrade plans

Maintain, upgrade and secure existing and already deployed infrastructure

Be using modern tools and good practices to deploy a scalable and reproducible infrastructure without SPoFs

What we are looking for:

You are curious, always a source of proposals

You are on the lookout for new technologies and are always ready to learn new things

You master Ansible, docker and other standard tools used everyday by our ops team

You are experienced with bash and you know your way around a linux-based OS (debian)

You are familiar with some of the tools or technologies listed below (we don’t expect anyone to master everything of course)

You have an appetite to optimize and automate systems

You have the security of the infrastructure in mind

You are fluent in English, both written and spoken

You have excellent interpersonal skills and are not afraid to solve problems

You are autonomous and able to tackle problems by yourself

What’s in it for you:

We offer a multicultural environment with teams in 5 countries across Europe (and expanding)

A context to work in where your ideas are listened to and valued, and in which you can easily contribute and make a difference

We are at a pivotal stage in our development with a significant acceleration of our growth and paradigm shift

We offer opportunities to learn and grow

Great work atmosphere and regular company events, barbecues, team buildings…

Partial remote work possible (2-3 days a week)

The technical scope of the Ops teams:

IaC scripting and automation under Ansible, bash and Python

IaC scripting for the modern kubernetes environment with ArgoCD and helm

Monitoring and observability of deployed infrastructure with Netdata, Prometheus and Grafana

Interact with dev and QA teams to provide tools and infrastructure evolution to fit their needs
