You will know we are the right place for you, if you are driven by:

  • Opportunities to learn and build your career.
  • Meaningful work in a stable and fast-paced company.
  • Diversity of people, projects, and platforms.
  • A supportive, fun, and inspiring place to work.

Job Overview:

We are looking for a KubeForge Engineer to join our Kubernetes-focused team. In this role, you will be responsible for operating, maintaining, and optimizing our Kubernetes environments—including OpenShift, RKE2, and vanilla Kubernetes clusters—across the organization. You will play a key role in ensuring high availability, performance, and security of our container orchestration platforms, directly impacting the reliability of services relied upon by the entire A1 Telekom group.

Role Insights:

  • Administer and maintain production Kubernetes clusters (OpenShift, RKE2, and vanilla Kubernetes) with a focus on availability and performance.
  • Deploy, configure, and manage containerized workloads using Kubernetes primitives (Deployments, StatefulSets, Services, ConfigMaps, Secrets).
  • Implement and enforce security best practices, including RBAC, network policies, Pod Security Standards, and certificate management.
  • Monitor cluster health using tools such as Prometheus, Grafana, and built-in OpenShift observability stack; respond to and resolve incidents.
  • Automate operational tasks and cluster management using Infrastructure-as-Code tools (e.g., Terraform, Ansible).
  • Collaborate with development teams to support CI/CD pipelines and containerized application deployments.
  • Conduct capacity planning, performance tuning, and regular maintenance activities (patching, upgrades).
  • Document cluster architectures, operational procedures, and runbooks.

What Makes You Unique:

  • 3+ years of hands-on experience with Kubernetes administration in production environments.
  • Deep understanding of Kubernetes architecture, networking (CNI plugins, Ingress, DNS), and resource management.
  • Experience with at least one managed Kubernetes platform (OpenShift preferred, EKS/AKS/GKE acceptable).
  • Proficiency in Linux system administration and command-line tools
  • Familiarity with monitoring, logging, and observability solutions (Prometheus, Grafana, ELK stack).
  • Strong problem-solving skills with the ability to work under pressure during incidents.
  • Fluency in English language.

Our gratitude for the job done will be eternal, but we’ll also offer you:

  • Valuable experience in one of the fastest-growing and most innovative industries.
  • Challenging assignments with strong opportunities for personal and professional growth in a multinational environment.
  • Hybrid working model supporting a healthy work-life balance.
  • Thousands of online and in-person Learning opportunities for you to grow.
  • Modern, open, and friendly work environment that fosters continuous learning and the development of both technical and soft skills.
  • Special employee tariffs and a wide range of attractive employee benefits.

If you have any questions, please do not hesitate to contact Svetlina Vazharova.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
