Résumé du poste

Skaleet is seeking an experienced DevOps Engineer to join the Infra team and own hosting and operations of our Cloud platforms across multiple client environments. You will automate deployments with Ansible, manage Kubernetes clusters, and contribute to the VMware/vSphere to Kubernetes migration.

You will monitor, maintain high availability for hundreds of VMs, participate in incident response, and collaborate with security and software teams.

Qualifications

• 4–5 years minimum experience as a DevOps Engineer or SRE in a SaaS production environment.
• Proven experience in a SaaS production environment with high criticality — you've been responsible for services that cannot go down.
• Ansible: you write playbooks from scratch; infrastructure runs on Ansible.
• Kubernetes in production: you've managed clusters, not just deployed to them.
• Strong Linux/Debian environment knowledge.

Responsabilités

• Maintain high availability of ~450 VMs across 3 OVH datacenters and 3 Kubernetes clusters (~20 nodes).
• Automate and improve deployments using Ansible and Rundeck; enable autonomous deployments.
• Develop and enhance monitoring with ELK stack and Site 24x7; improve CI/CD tooling.
• Act as Level 3 support for infra issues and unblock cross-team problems.
• Contribute to VMware/vSphere to Kubernetes migration and multi-tenant infra initiatives.

Description du poste

Skaleet is a fast-growing B2B fintech specializing in Core Banking Solutions. We help financial institutions in 15+ countries innovate, scale, and deliver superior banking experiences to millions of end-customers.

Our infrastructure is critical: every client runs on its own dedicated platform, meaning 50+ environments to operate in production, each with its own specificities.

You will join the Infra team and work on the hosting and operations of Skaleet's Cloud platforms across all clients, as well as common infrastructure services (RabbitMQ, Vault, Redis, logs…), in close collaboration with our software development and security teams. The first 6 months will be focused on ramp-up and operational ownership. From there, you'll be fully autonomous on the vast majority of topics — including our ongoing strategic migration from VMware/vSphere to Kubernetes.

Operational Maintenance

• Ensure high availability of ~450 VMs across 3 OVH datacenters (Roubaix, Strasbourg, Frankfurt) and 3 Kubernetes clusters (~20 nodes).
• Monitor infrastructure and qualify incidents escalated by support teams

Infrastructure as Code (IaC)

• Automate and improve application deployments and system updates using Ansible and Rundeck — Ansible covers our entire infrastructure, this is the core of the role.
• Provide tooling to support and other teams to make them autonomous on deployments without breaking production.
• This is the team's main ongoing project. Newer product modules (credit, savings) already run on Kubernetes.
• Objective: build a new Kubernetes-native platform for new clients, then migrate existing platforms progressively.
• Network knowledge is a strong plus — legacy VMware configurations are complex and sometimes undocumented.

Monitoring & Alerting

• Develop and improve service monitoring tools (ELK stack: Elasticsearch + Kibana, Site 24x7).
• Enhance our status page and automate alert creation.
• In collaboration with development teams, improve build and release tooling (GitLab CI) to move toward continuous deployment.

Level 3 Support

• Act as the last escalation point for infrastructure-related issues raised by developers and project managers.
• ~60% of the work is unplanned — troubleshooting, ad hoc fixes, cross-team unblocking. Autonomy and initiative are key.

Infrastructure (OVH Cloud) > VMware/vSphere (~450 VMs, 5 DCs) · Kubernetes with Helm (3 clusters, ~20 nodes)

High Availability y > RabbitMQ · Vault · ProxySQL · Redis

Must-Have

• 4–5 years minimum experience as a DevOps Engineer or SRE.
• Proven experience in a SaaS production environment with high criticality — you've been responsible for services that cannot go down.
• Ansible: you write playbooks from scratch, not just read them — our entire infrastructure runs on Ansible.
• Kubernetes in production: you've managed clusters, not just deployedto them.
• Strong Linux/Debian environment knowledge.

Nice to have

• Network knowledge (firewalls, routing) — a strong plus for the VMware migration.
• Experience working with remote teams.
• VMware/vSphere knowledge.

The Profile That Works Here

• Autonomous — you don't wait for a ticket to fix something you see.
• Comfortable in a complex, multi-tenant environment (50+ client platforms, each unique).
• At ease working with remote colleagues
• Pragmatic and curious — not looking to challenge every architectural decision, but always looking to improve.
• 25 days paid vacation + 12 RTT per year.
• Swile card for daily meals
• Brand-new offices in Boulogne-Billancourt, right next to Metro 10.

Recruitment Process

• Video call with Maxime, Human Ressources Manager (30 min).
• Technical interview with Jonathan and a team member — deep dive into the role and your experince (60 min).
• Final meeting in Boulogne with Geoffroy ( General Secretary) (60 min).
