Own and evolve a hybrid OpenShift/Kubernetes and Azure platform supporting production workloads. Responsibilities include cluster and cloud infrastructure architecture, infrastructure as code, CI/CD platform management, security, incident troubleshooting, capacity and cost optimization, observability, deployment pattern design, documentation, and mentoring. The role requires extensive hands-on experience with OpenShift or Kubernetes, Azure services, container security, distributed systems, automation, microservices, event-driven architectures, and GitOps.

You will help keep our OpenShift container platform healthy, secure and up to date, and act as a technical point of contact for the application teams that rely on it. This is a hands-on engineering role for someone with a solid Linux background and a few years of real-world Kubernetes experience who wants to work on a platform at genuine scale, with all the complexity that mixed cloud, on-prem and edge environments bring.Your responsibilities
  • Operate, patch and upgrade OpenShift clusters and their underlying Linux hosts across cloud, on-premises and remote environments
  • Monitor platform health, respond to incidents and alerts during working hours, and drive root-cause analysis and follow-up
  • Work with development teams to understand their applications and design how they run on OpenShift
  • Author, review and maintain Helm charts for applications, following and contributing to the team's shared chart standards and library charts
  • Maintain and extend platform components delivered through GitOps, and contribute improvements back to shared configuration and charts
  • Manage platform-level concerns such as certificates, secrets, image registries, ingress and observability
  • Automate recurring operational tasks with scripting and infrastructure-as-code
  • Write and maintain clear runbooks, documentation and knowledge-base articles
  • Participate in change management: prepare, document and execute changes according to ITIL-style processes
  • Collaborate daily with colleagues in Belgium and other locations, working across time zones
Your profile
  • Hands-on experience operating Kubernetes in production; OpenShift experience is a strong plus
  • 2-5 years of professional experience in Linux system administration or engineering (RHEL/CentOS-family preferred)
  • Good understanding of containers, networking (DNS, TLS, load balancing, ingress), storage and Linux security fundamentals
  • Strong, practical knowledge of Kubernetes resources and how they fit together, and proven experience designing and writing Helm charts, not just deploying existing ones
  • Solid understanding of DevOps principles and practices: infrastructure and configuration as code, version-controlled change, CI/CD, automated testing, immutable deployments, and a "you build it, you run it" approach to reliability
  • Experience with GitOps (Argo CD)
  • Familiarity with observability tooling (Prometheus, Grafana, Alertmanager, centralized logging)
  • Exposure to any of the following is a plus: Ansible, cloud platforms (Azure), certificate management, secrets management, VMware/vSphere
  • Certifications (RHCSA, CKA, etc.) are welcome but not required. We care about what you can do, not what you hold.
  • Fluent professional English, spoken and written. This is essential, as you will work daily with an international team and produce written documentation and change records
  • Clear communicator who can explain technical issues to both engineers and non-technical stakeholders
  • Structured and methodical troubleshooter who documents what they find and follows through
  • Ownership mindset: you take responsibility for the platform's health rather than waiting to be assigned tasks
  • Comfortable working in a distributed team and asking for help or clarification early
  • Service-oriented attitude towards application teams: patient, responsive and constructive
  • Curious and willing to learn: the platform, the tooling and the business all keep evolving
Our offer
  • An extensive mobility program for a healthy work-life balance.
  • A permanent training track which allows you to develop yourself personally and professionally.
  • A stimulating, innovative workplace with numerous growth opportunities.
  • A people-oriented environment with an interactive health program and a focus on employee wellbeing.
