Systemadministrator Linux (m/w/d) | in Freiburg im Breisgau

About This Opportunity

We are representing a growing, family-led technology organization based in Freiburg that develops hardware and software solutions for industrial machine vision and automation. Their systems are deployed in over 15,000 machines worldwide.

As a Linux System Administrator, you'll join a deliberately small IT team with significant room to shape technical direction. Rather than rigid corporate structures, you'll experience short decision paths, direct communication with leadership, and the opportunity to actively influence technical choices.

The technological focus is squarely on Linux and open source. In the coming years, you'll tackle exciting projects: migrating existing applications to open source alternatives, expanding cyber security and resilience capabilities, and continuously developing an internal Linux-based AI server.

If Linux is your technical home and you prefer building new solutions over simply maintaining existing systems, this is your chance to shape an IT landscape for the long term.

Responsibilities

• Manage and optimize the Linux system landscape along with associated network and IT infrastructure
• Drive continuous development of existing systems and guide migrations from proprietary software to suitable open source alternatives
• Work with virtualization and container technologies including Proxmox, Docker, and vSphere
• Automate processes using Python, Ansible, and comparable technologies
• Advance security and resilience initiatives, addressing technical requirements around NIS 2, GDPR, CRA, and TISAX
• Maintain and expand the company's internal Linux-based AI server, creating secure infrastructure for internal artificial intelligence use
• Resolve complex internal IT issues for predominantly technical users, focusing on second and third-level support

What We're Looking For

• Completed training as an IT specialist, IT system administrator, completed computer science degree, or comparable qualification
• Minimum two years of professional experience with clear focus on Linux administration following completion of your training or studies
• Very strong Linux knowledge—you already work routinely with Linux and don't need to learn the operating system from scratch
• Solid understanding of network technology, network protocols, and IT infrastructure
• Experience with virtualization or container technologies such as Proxmox, Docker, or vSphere
• Knowledge of automation, for example with Python, Ansible, or comparable technologies
• Enthusiasm for open source and interest in building an IT landscape on open and secure solutions for the long term
• Business-fluent German at minimum C1 level and fluent English
• Independent, pragmatic working style with desire to actively shape technical decisions and try new solutions together as a team
• Knowledge of Nextcloud, Open Xchange, Nginx, pfSense, OpenVPN, Git, or Ceph, as well as experience with IT security, are advantageous

What's On Offer:

• Room to shape how internal IT evolves in Linux, open source, cyber security, resilience, and automation
• Exciting future projects including open source migrations, IT security expansion, and an internal Linux-based AI server
• Direct collaboration with leadership, short decision paths, and significant freedom in technical solutions
• Flexible working hours without fixed core hours; typically one day per week remote, with more possible by arrangement
• 30 vacation days with individual solutions for extended time off when needed
• Annual performance bonus that has reached several thousand euros in successful years
• Subsidized national transit pass, bike leasing, company parking, free electric vehicle charging, and pool vehicles for business appointments
• Fitness membership, on-site bouldering wall and table tennis, plus colleague-organized activities like climbing, mountain biking, and kayaking
• Summer party, holiday celebration, rooftop barbecues, and multi-day developer camps for exploring new technologies
• Individually tailored professional development and a mentor from another department as your personal sounding board
