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:
- A three-week onboarding to get to know our product, our teams and our culture!
- A multicultural environment with colleagues coming from 5 different countries and 10 different nationalities 🇨🇵 🇩🇪 🇪🇦 🇮🇹 🇬🇧
- First choice IT equipment 
- Our office is based right in the heart of Paris, 100 meters from the Opera Garnier!
- Remote friendly: up to 3 days per week
- Lunch vouchers: Swile card
- Team building events : Ibiza, Porquerolles, Corsica… what’s next? 😎
- Be part of a company at a key moment of its growth, with lots of opportunities 🚀
- You’ll be lucky to join a team that is big enough to thrive but also small enough to actually have an impact on the success of the organisation!
- 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 offer opportunities to learn and grow
