• Automate Kubernetes cluster provisioning using Cluster API (CAPI) integrated with KubeVirt.
• Manage and monitor multi-tenant Kubernetes clusters and workloads using Helm and GitOps (FluxCD).
• Ensure high availability of workloads using proper node/pod-level scheduling, storage, and network configurations.
• Implement network policies, ingress controllers (NGINX/Kong), and secure container runtime environments.
  
   

GitOps (FluxCD) 

 

• Maintain and extend KubeVirt infrastructure for Kubernetes cluster lifecycle management.
• Use FluxCD to drive declarative GitOps workflows for Kubernetes and VM infrastructure.
• Collaborate with automation teams to integrate Git workflows with Infrastructure-as-Code practices.
  
   

Microsoft Services: Active Directory, DFS, Certificates

 

• Administer and maintain multi-domain Active Directory environments including GPO, OU management, and RBAC.
• Support and troubleshoot Distributed File System (DFS) replication and availability.
• Manage internal certificate authority (ADCS) services, including certificate templates, auto-enrollment, and PKI troubleshooting.
  
   

Email Infrastructure

Microsoft 365 & Mimecast

 

• Oversee and support Microsoft 365 Exchange Online environment including mail flow, compliance, and hybrid scenarios.
• Configure and manage Mimecast for email security, archiving, and continuity.
• Monitor mail delivery issues and coordinate remediation with internal and external support teams.
  
   

Linux

 

• Administer Linux servers (RHEL/CentOS/Alma Linux) in clustered and standalone configurations.
• Conduct OS hardening, patching, performance tuning, and kernel-level debugging.
  
   

Automation, Monitoring & Performance Optimization 

 

• Automate operational workflows using IaC/OpenTofu, Ansible, and shell scripting.
• Monitor system health using Prometheus, Grafana, AlertManager, and custom metrics dashboards.
• Perform capacity planning, performance optimization, and disaster recovery (DR) simulations.
  
   

Documentation, Collaboration & Mentorship

 

• Maintain detailed documentation for systems, architecture, runbooks, and SOPs.
• Collaborate with software engineers, DevOps, and IT support teams for smooth infrastructure operations.
• Mentor junior engineers and support staff in modern cloud technologies and IT best practices.
  
   

The Must-Haves - 

 

• 7+ years in systems engineering, virtualization, and cloud infrastructure.
• Strong hands-on experience with KubeVirt, Kubernetes, and CloudStack.
• Fluency with GitOps tools like FluxCD, Helm, and Kubernetes RBAC.
• Proficiency in Active Directory, GPO, DNS/DHCP, DFS, and internal PKI. Familiarity with Exchange Online, Mimecast, SPF/DKIM/DMARC, and email routing.
• Solid scripting and automation skills using Bash, Ansible, PowerShell, or Python.
• Strong knowledge of monitoring, logging, and performance analysis tools.
• Excellent troubleshooting, documentation, and incident resolution skills.
  
   

Preferred Qualifications

 

• Experience with hybrid cloud or multi-cloud setups (Azure, AWS, GCP).
• Familiarity with Service Mesh (Istio/Linkerd), SSO integrations (OAuth2/OIDC).
• Experience with security compliance and data protection in enterprise IT.
• Background in email archiving, DLP, and mail gateway policies.
• Knowledge of enterprise backup/restore and DR solutions for Kubernetes and VMs
