Vollständige Stellenbeschreibung

Unix System Administrator – High-Security IT Operations (m/f/d)

Help operate IT systems where reliability and security are truly important.

At Data-Warehouse GmbH, you will work in high-security, mission-critical IT environments where stable systems, precise operations, and a strong focus on security are essential.

We are looking for a Unix System Administrator (m/f/d) with a strong hands-on approach, solid troubleshooting skills, and the motivation to keep complex IT environments secure, reliable, and well-documented.

You will join an experienced international team and contribute to systems that support demanding stakeholders and security-sensitive projects.

At a Glance

Permanent full-time position
Immediate start
Location: North Munich, Germany
On-site role due to security requirements
Focus: Unix/Linux, Red Hat Enterprise Linux, secure IT operations
Security clearance required or willingness to go through the process

Your role

In this role, you will support the operation, administration, and continuous improvement of Unix/Linux-based systems, primarily in Red Hat environments.

Your responsibilities include:

Administer Unix/Linux-based operating systems, including troubleshooting, installation, and setup.
Maintain compliance with security policies, including patch management and vulnerability remediation.
Perform backups and recovery using tools such as Netbackup.
Basic hardware management including racking, card/disk replacements, attaching to network(s), etc.
Installing third-party software following the instructions provided.
Document architecture, procedures, and operational guidelines for system administration.

Willingness to learn and acquire new skills (including acquiring relevant certifications).
Willingness to work on a rotating schedule (to cover the service hours) and to work outside of regular working hours (usually one Saturday per month).

Your profile

Strong expertise in Unix/Linux system administration (RHEL8, RHEL9, or similar).
Strong troubleshooting skills for Unix/Linux systems.
Working with ticket system for incidents, problems, change management and configuration management.
Certifications such as RHCE (Red Hat Certified Engineer) or similar are an advantage.

What Makes This Role Special

This isn't just another system administration role.

You will work in an environment where your contributions have a real impact: systems must be secure, available, well-maintained, and compliant. Your work helps ensure that critical IT infrastructures remain stable and trustworthy.

At the same time, you will have the opportunity to deepen your technical knowledge, gain experience in high-security environments, and further your professional development through targeted training and certifications.

What We Offer

Permanent employment at a stable, owner-managed German IT company
Competitive salary and performance-based bonus
Work on high-security IT and cybersecurity-related projects
Individual training and development, including opportunities for certification
German courses, if needed
Relocation Support
Meal allowance through our on-site cafeteria
Sports and fitness benefits, including company soccer every two weeks
A work environment based on trust, responsibility, and long-term cooperation
