Description:

We are seeking a skilled Junior Kubernetes Administrator with strong background in Cloud technologies (AWS, Azure) to manage, configure, and support Kubernetes infrastructure in a dynamic, high-availability environment. The Engineer collaborates with Development, DevOps and other technology teams to ensure that the Kubernetes platform ecosystem is reliable, scalable and efficient.

We will count on you to:

• Manage and resolve incidents, service requests and changes through shared operational queues.
• Troubleshoot Kubernetes platform issues and perform cluster maintenance, upgrades and configuration changes.
• Support container technologies, certificate management and platform monitoring.
• Collaborate with application, DevOps, security and infrastructure teams to resolve technical issues.
• Maintain clear documentation of configurations, changes and operational procedures.
• Contribute to the reliability, security and continuous improvement of the Kubernetes platform.

What you need to have?

• Minimum 2 years’ experience in data center operations, systems engineering or a similar hands‑on infrastructure role.
• Intermediate to advanced networking knowledge, with practical experience troubleshooting switch/router behaviour, VLANs, subnetting, routing, SAN networking and basic load balancing.
• Intermediate to advanced infrastructure and cloud experience: hands‑on familiarity with server and storage platforms, virtualization technologies and cloud platforms.

• Experience supporting Kubernetes platforms in large-scale, global or hybrid-cloud environments.
• Kubernetes certifications such as CKA (Certified Kubernetes Administrator) or equivalent practical knowledge.
• Strong documentation skills and experience working within structured incident, problem and change-management processes.
