Key Responsibilities

• Build, deploy, and maintain Kubernetes clusters on physical servers.
• Perform rack/stack, cabling, hardware setup, and infrastructure bringup activities.
• Manage provisioning workflows including bootstrapping nodes, networking configurations, load balancers, and cluster dependencies.
• Configure and optimize storage solutions for Kubernetes (Ceph, local PVs, distributed storage, etc.).
• Implement monitoring, alerting, and cluster health dashboards for reliability and uptime.
• Troubleshoot node failures, network issues, cluster degradation, and performance bottlenecks.
• Automate infrastructure lifecycle using InfrastructureasCode (IaC) tools such as Terraform and Ansible.
• Maintain cluster security, RBAC policies, certificate rotation, and secure deployment workflows.
• Collaborate with platform, hardware, and DevOps teams to ensure endtoend infrastructure stability.
• Document procedures, architecture diagrams, and operational best practices.

Mandatory Skills

• 6-8 years of experience as an Infrastructure Engineer / Systems Engineer.
