## Description

Riot is expanding into hyperscale data centers for AI and HPC clients, and the internal systems that run our sites need to scale with it. As a Systems Administrator II, you'll operate and improve Riot's server, virtualization, and Linux infrastructure across multiple sites.

You'll own the Ubuntu Server fleet and Proxmox virtualization platform end to end, combining hands-on Linux and hypervisor administration with DevOps practices such as infrastructure as code, configuration management, and observability across on-premises and cloud environments.

This position will be hybrid based in our Austin, Texas office.

What you'll do

 * Build, harden, and maintain Ubuntu Server LTS hosts, including networking, storage, services, logging, and LTS upgrades with tested rollback paths.
 * Administer Proxmox VE clusters, including storage, networking, role-based access control, API tokens, and firewall rules.
 * Standardize VM provisioning with cloud-init templates and protect workloads through Proxmox Backup Server jobs, retention, verification, and regular restore tests.
 * Support Nutanix and VMware workloads through their remaining lifecycle and migrations.
 * Automate provisioning, configuration, and scaling of compute, storage, and network resources across cloud and on-premises environments.
 * Keep systems healthy by maintaining monitoring, alerting, and logging, tracking capacity, and resolving incidents through root cause.
 * Own patch and vulnerability remediation across Linux and Windows, meeting defined SLAs and enforcing security best practices across all infrastructure.
 * Partner with cross-functional teams on deployments, making changes through change management and keeping runbooks and documentation current.
