About The Position

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.

Requirements

Bachelor’s or Master’s degree in Electrical Engineering, Telecommunications, Computer Science, or a related field.
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.
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.

Nice To Haves

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.

Responsibilities

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.
