Kubernetes Platform Administrator

About the Position

Kubernetes Platform Administrator

Lisboa, Portugal

Own the Platform. Not Just the Tickets.

We're looking for a Kubernetes / OpenShift Platform Administrator who wants real ownership of a production container platform - from cluster lifecycle to the GitOps automation on top of it.

Why this role is worth your attention:

• You own the platform, end to end. Cluster upgrades, quotas, resource limits, lifecycle management - the OpenShift estate is yours to run and evolve, not just monitor.

• Automation, not toil. You'll automate platform operations with Operators (OLM) and drive everything through GitOps with Argo CD. Declarative, version-controlled, reproducible. No snowflake clusters.

• You build the paved road. Maintaining the service catalogue with Helm charts and templates means your work is leverage - other engineers move faster because of what you built.

• A stack that keeps your CV sharp. OpenShift, Istio service mesh, Argo CD, Helm, Prometheus, Grafana, Elasticsearch, Azure. Every one of these is in demand and rising.

• Security is yours, not an afterthought. RBAC, LDAP/AD integration, Security Context Constraints, hardening - you own the platform's security posture.

• You're the technical authority. You're the interface with the infrastructure provider - the person they answer to.

• Structured, sane delivery. 2-week sprints. You'll know what you're building this fortnight, and you won't spend your life firefighting.

Responsibilities

• Own the platform, end to end.
• Automate platform operations with Operators (OLM).
• Drive everything through GitOps with Argo CD.
• Maintain the service catalogue with Helm charts and templates.
• Ensure the platform's security posture.

Requirements

• What you bring:

  • Strong Azure administration experience.
  • Hands-on Kubernetes and/or OpenShift in production.
  • GitOps / Argo CD experience.
  • Helm, Operators, platform automation.
  • RBAC, LDAP/AD integration, security hardening.
  • Monitoring & logging (Prometheus, Grafana, Elasticsearch).
  • Fluent Portuguese and English.
  • Strong troubleshooting and collaboration instincts.

• Certifications:

  • Certified Kubernetes Administrator (CKA) - highly valued.
  • Microsoft Azure Administrator Associate & DevOps Engineer Expert - Mandatory.

We Offer

• Opportunity to own and evolve a production container platform.
• Work with cutting-edge technologies.
• Be part of a structured, sane delivery process.
• Competitive salary (not specified).
• Professional growth opportunities.
