We are seeking a highly skilled Devops Engineer with strong expertise in Kubernetes-based ecosystems, container orchestration, and cloud-native technologies. The ideal candidate will have hands-on experience in designing, deploying, and managing large-scale containerized applications using SUSE Rancher, Kubernetes, and associated tools. You will work closely with cross-functional teams to build and optimize scalable, secure, and resilient infrastructure solutions.
Key Responsibilities
- Design, implement, and maintain Kubernetes clusters using SUSE Rancher (RMS), RKE2, and related orchestration tools.
- Manage centralized platforms through Rancher UI with proper RBAC implementation.
- Configure and optimize networking with Calico (CNI) and service discovery via CoreDNS.
- Implement container runtime environments with Containerd/Docker.
- Ensure container security and compliance using SUSE NeuVector and SELinux.
- Deploy and manage monitoring, observability, and logging stacks including:
- Grafana, Prometheus, Grafana Loki, Grafana Mimir, Grafana Alloy, Fluent Bit, kube-prometheus-stack, OpenTelemetry Collector, Prometheus Exporters.
- Manage storage and persistence solutions such as MinIO, Longhorn, NFS-CSI, and Harbour (Container Registry).
- Administer and optimize database and middleware services:
- PostgreSQL 16 (with Master/Slave replication), PGPool2, NGINX (as Kubernetes Reverse Proxy).
- Work with RHEL 8.5/9.0 environments and Linux command-line tools for infrastructure operations.
- Provide technical solutions, troubleshooting, and performance tuning for production systems.
- Collaborate with DevOps, security, and development teams to ensure best practices in containerized environments.
