 * 10+ years expert-level Linux administration experience, with production experience on Red Hat Enterprise Linux or its derivatives (Rocky Linux, AlmaLinux, CentOS Stream).
 * 5+ years of significant production experience operating Linux KVM/libvirt at fleet scale, including performance-sensitive workloads.
 * 10+ years of experience building an automated provisioning pipeline from bare metal to running workload.
 * 5+ years of experience with demonstrated host performance tuning: CPU pinning and isolation, NUMA (Non-Uniform Memory Access) memory placement, and interrupt affinity. (Replace Linux with Kubia)
 * 5+ years of experience deploying and operating Prometheus and centralized logging.
 * 5+ years of experience patching production fleets across multiple sites with minimal service impact., * RHCE (Red Hat Certified Engineer) or RHCA (Red Hat Certified Architect) certification is highly desirable.
 * Familiarity with SR-IOV (Single Root I/O Virtualization) or PCI passthrough for high-throughput virtual network functions.
 * Familiarity with Userspace or kernel-bypass packet processing.
 * Experience with immutable or API-managed host operating systems.
 * Automation driven from an inventory/IPAM (IP Address Management) system such as NetBox.
 * Security hardening in performance-sensitive environments.

## Description

In this role you will owns our Linux KVM (Kernel-based Virtual Machine) hypervisor platform and the automation used to provision, patch, monitor, and secure it. The successful candidate will define and maintain golden configurations, build the bare-metal provisioning pipeline, and operate the monitoring and log collection stack used across the team.

What You'll Do

 * Develop and maintain hypervisor golden configurations: host build standards, kernel and performance tuning, and VM (Virtual Machine) templates, including connectivity testing.
 * Manage the hypervisor lifecycle: image builds, patching and update schedules, staged rollouts, and rollback procedures.
 * Build and maintain automated bare-metal provisioning: network boot, unattended installation, per-host configuration, and local package repositories.
 * Build and operate the monitoring platform: Prometheus metrics collection covering the operating system, hypervisor, and hardware layers, with dashboards and alerting.
 * Build and operate centralized log collection for the hypervisor fleet.
 * Implement configuration management and drift detection across the hypervisor fleet.
 * Maintain the security baseline: CIS (Center for Internet Security) hardening, automated compliance scanning, vulnerability triage and patching, and centralized identity and access management.
 * Maintain CI (Continuous Integration) and testing for infrastructure code.
