Key Responsibilities
We offer you the unique opportunity to apply and develop your skills with a diverse and geographically distributed technology team. You will play a key role in building and running Kubernetes platforms that host mission-critical and GPU-accelerated workloads.
The following are the main duties you will do as part of this job:
- Install, configure and operate production Kubernetes clusters, primarily RKE2, across on-premise, air-gapped and hybrid environments
- Set up and operate SUSE Rancher Manager in high availability: installation, upgrades, backup and restore, authentication and RBAC, and provisioning or importing downstream clusters
- Automate infrastructure provisioning and configuration using Infrastructure as Code (Terraform and Ansible)
- Troubleshoot and investigate platform issues end to end (nodes, pods, CNI networking, DNS, ingress, storage, certificates, etcd and the control plane) and drive root-cause analysis to closure
- Set up and operate SUSE Rancher Manager in high availability: installation, upgrades, backup and restore, authentication and RBAC, and provisioning or importing downstream clusters
- Deploy and operate the NVIDIA GPU Operator on RKE2, including driver and container toolkit configuration for RKE2's embedded containerd, the device plugin, GPU Feature Discovery and DCGM monitoring
- Configure GPU sharing (MIG and time-slicing) and support the scheduling and operation of AI/ML workloads on GPU nodes
- Build and maintain CI/CD pipelines (e.g., GitLab CI, Jenkins, GitHub Actions) for application and platform delivery
- Implement GitOps with Rancher Fleet, Argo CD or Flux, keeping Git as the single source of truth for cluster configuration and deployments
- Package and manage workloads with Helm and Kustomize
- Deploy and operate Istio: traffic management, ingress and egress gateways, mTLS and authorization policies, and mesh troubleshooting
- Operate SUSE Virtualization (Harvester) to run VM workloads alongside containers and to host RKE2 guest clusters
- Implement monitoring, logging and alerting with Prometheus, Grafana and Rancher Monitoring and Logging
- Harden clusters using CIS benchmarks (including the RKE2 CIS profile), Pod Security Admission, network policies and secrets management
- Plan and execute Kubernetes, RKE2 and Rancher upgrades with minimal downtime
- Design and test backup and disaster recovery, including etcd snapshots, Rancher backups and workload backup (e.g., Velero)
- Create and maintain runbooks, playbooks and platform documentation
- Conduct knowledge transfer and training sessions for customer and internal teams
- Work closely with customer stakeholders in on-site engagements
Our ideal candidate will fulfill the following requirements:
- 5+ years of hands-on experience in IT, with 3+ years administering Kubernetes in production
- Strong Kubernetes troubleshooting and investigation skills:
- Systematic debugging with kubectl, events, logs, crictl and node-level tools
- Diagnosing networking, DNS, storage, scheduling, certificate and control-plane issues
- Root-cause analysis and clear incident write-ups
- Hands-on experience with Rancher Manager setup and day-2 operations
- Experience deploying and operating the NVIDIA GPU Operator, ideally on RKE2
- Automation with CI/CD and GitOps:
- GitLab CI, Jenkins or GitHub Actions
- Fleet, Argo CD or Flux
- Helm and Kustomize
- Hands-on experience with Istio service mesh
- Infrastructure as Code: Terraform and Ansible
- Strong Linux administration (SLES / SLE Micro, RHEL or Ubuntu) and networking fundamentals (TCP/IP, DNS, load balancing, TLS)
- Monitoring and observability: Prometheus, Grafana and centralized logging
- Strong Bash scripting; Python or Go is a plus
- Bachelor's degree in Computer Engineering, Computer Science, Engineering, or a related field
- Strong experience working in on-premise enterprise environments, including air-gapped setups
- Ability to work independently in customer-facing roles
- English (advanced); Arabic language skills are a strong advantage
Hands-on production experience with these products will strongly differentiate a candidate. Candidates without it must, at a minimum, be able to explain:
- RKE2: SUSE's security-focused, CNCF-certified Kubernetes distribution; server and agent nodes, embedded containerd, etcd, configuration through config.yaml, CIS-hardened defaults and air-gapped installation
- Rancher: multi-cluster management; the Rancher Manager (local) cluster versus downstream clusters, cluster agents, projects and RBAC, Fleet and the app catalog
- SUSE Virtualization (Harvester): hyperconverged infrastructure built on Kubernetes, using KubeVirt for virtual machines and Longhorn for storage, managed from Rancher
- SUSE Security (NeuVector) and SUSE Storage (Longhorn)
- CNI expertise: Canal, Calico or Cilium
- Secrets management: HashiCorp Vault, Sealed Secrets or External Secrets Operator
- Private registries and air-gapped image management (e.g., Harbor)
- AI/ML platform tooling (e.g., Kubeflow, KServe, Ray)
- Other Kubernetes platforms: Red Hat OpenShift, EKS, AKS or GKE
- Certified Kubernetes Administrator (CKA)
- Certified Kubernetes Security Specialist (CKS)
- Certified Kubernetes Application Developer (CKAD)
- SUSE Rancher certification (Administrator or Deployment Specialist)
- Istio Certified Associate (ICA)
- NVIDIA-Certified Associate: AI Infrastructure and Operations
Experience: 5+ years (3+ years hands-on Kubernetes)
