What You Will Do

• Design, build, and manage highly available Kubernetes clusters across hybrid environments (on-premises and cloud platforms such as AWS EKS, Azure AKS).
• Deploy and manage applications manually using tools such as kubectl and Helm, with growing integration of GitOps practices (e.g., ArgoCD).
• Implement and manage observability stacks using Prometheus, Grafana, Loki, and Mimir to monitor infrastructure, applications, and system performance.
• Define, monitor, and improve SLA/SLO/SLI metrics and alerting systems to ensure platform reliability.
• Automate provisioning and configuration of infrastructure using Terraform, Helm, and scripting languages (e.g., Bash, Python).
• Plan, implement, and test backup and disaster recovery (DR) strategies using tools like Velero, Commvault, etc.
• Manage Kubernetes-native networking, storage, and security configurations (Ceph, NFS, Ingress, PodSecurityPolicies, etc.).
• Configure and enforce Kubernetes security best practices using RBAC, OPA/Gatekeeper, NetworkPolicies, and secrets management tools.
• Integrate and operate Kubernetes ecosystem tools such as Karpenter, MicroK8s, Service Meshes, and kubectl plugins.
• Conduct root cause analysis (RCA) and lead resolution efforts for incidents.
• Participate in the on-call rotation for platform availability and incident management.
• Maintain up-to-date documentation, architecture diagrams, runbooks, and SOPs.
• Mentor engineers and advocate for Kubernetes, security, observability, and deployment best practices across teams.
• Continuously stay informed of industry trends in container orchestration, GitOps, security, and cloud-native tooling

What You Need to Be Successful

• 6-9 years of IT/Infrastructure/DevOps experience, with 5+ years in Kubernetes operations in production environments.

• Intermediate-level experience in Kubernetes Security, including:
• Cluster hardening, secrets management
• Pod Security Standards (PSS), OPA/Gatekeeper
• Network policies, image scanning, and runtime protections
• Intermediate experience with ArgoCD for GitOps-style Kubernetes deployments.
• Solid proficiency in Linux system administration (Ubuntu, CentOS, RHEL) and troubleshooting.
• Hands-on experience with Kubernetes-native storage (e.g., Ceph, NFS) and persistent volume
