About The Position

The Proxmox Virtualization Systems Administrator deploys, manages, and maintains Tract Capital’s enterprise virtualization stack, primarily Proxmox Virtual Environment (PVE) and Proxmox Backup Server (PBS), across corporate and data center environments. The role owns the design, procurement, and deployment of compute and storage hardware and the hypervisor and backup platforms that support IT and OT systems. It also serves as an escalation path for operational issues, security concerns, and performance problems involving the hypervisor and backup platforms. The position works with infrastructure, network, security, and application teams to support existing systems and plan for new workloads. It also contributes to virtualization strategy, infrastructure capacity planning, automation, documentation, backup and disaster recovery readiness, and operational support. The role is based in the Denver, CO office or Seattle, WA, both hybrid, with occasional travel estimated at 10–20% to data center sites.

Requirements

Bachelor’s degree in Computer Science, Information Technology, or a related field, or equivalent practical experience.
At least 3 years of hands-on systems administration experience, including 1–2+ years directly administering Proxmox VE/PBS, or comparable hypervisor experience with demonstrated ability to transition to Proxmox.
Experience administering Proxmox VE and Proxmox Backup Server, including clustering, high availability, and storage backends such as ZFS, Ceph, NFS, or iSCSI.
Strong Debian-based Linux systems administration and command-line skills.
Networking fundamentals relevant to virtualization, including VLANs, bridging and bonding, software-defined networking, and firewalling.
Scripting or automation experience with Bash, Python, or Ansible, and familiarity with the Proxmox API.
Knowledge of backup and disaster recovery concepts, including retention, deduplication, encryption, and restore validation.
Strong troubleshooting and root-cause analysis skills under time pressure.
