System Administrator

Tartu / Tallinn, Estonia

We’re looking for a hands-on System Administrator to join our Infrastructure team. You’ll help operate and maintain the hybrid infrastructure that keeps Axinom running every day.

This is a broad, practical role for someone who enjoys taking ownership of infrastructure, solving technical challenges, documenting their work, and ensuring our systems remain reliable, secure, and well maintained.

You’ll join a collaborative and supportive team that works closely together, shares knowledge, and continuously develops its skills. We actively explore new technologies and modern infrastructure practices, giving you the opportunity to work with the latest innovations while helping deliver reliable internal services across the company.

What you’ll do

  • Administer and maintain our virtualization environment (Proxmox)

  • Own backup administration and disaster recovery using Veeam and/or Proxmox Backup Server, including regularly verifying that restores work as expected

  • Assist with managing company endpoints through Microsoft Intune (MDM), including device provisioning, configuration, and patch/update management across Windows and macOS

  • Perform general Linux and Windows system administration, keeping servers and services healthy, secure, and up to date

  • Support users with a variety of IT requests - from access management and devices to day-to-day technical issues

  • Maintain clear documentation of infrastructure, changes, and procedures, while providing responsive support to colleagues across multiple offices

What we’re looking for

  • Virtualization experience - hands-on experience with hypervisors or virtualization platforms. Experience with Proxmox is an excellent match, but candidates with experience in other virtualization platforms are also encouraged to apply

  • Cloud infrastructure - some experience with cloud platforms such as Azure, AWS, Hetzner Cloud, or similar

  • Backup administration - understanding of backup and recovery concepts. Experience with Veeam and/or Proxmox Backup Server is highly desirable

  • Networking - solid understanding of networking fundamentals

  • Linux and Windows Server administration - comfortable working across both operating systems

  • Communication - good written and spoken English for working in a distributed team

Nice to have skills

  • Server hardware administration (e.g. Dell PowerEdge)

  • NAS and SAN administration (e.g. Synology, Fujitsu Eternus)

  • Microsoft Intune / MDM experience managing Windows and macOS endpoints

  • Experience with monitoring and logging platforms (e.g. Zabbix, Graylog)

  • Experience with scripting or workflow automation (PowerShell, Bash, n8n, etc.)

  • Experience with Docker or other container technologies
