System Engineer (m/w/d) - Virtualization & Platform

You administer not just, you shape! At our company, you modernize data center infrastructures for medium-sized enterprises and critical infrastructure. From planning to stable operation.

We are Transition Engineers, not classical IT service providers. That means: We advise not just, we implement. We disappear not after the concept, but stay until the solution runs. Vendor-neutral, business-stable, transfer-capable.

The Special: You switch between projects and operation. You lead your own migration and modernization projects (with mentoring), see new technologies and environments – but without the restless lifestyle of a classical consultant. No constant stress, no permanent customer change, no hotel-hopping.

Work Model: Remote from anywhere in Germany. Team meetings 1-2 times/month in Koblenz. Customer visits 1-2 times/month (data centers, migrations, commissioning).

Tasks

You can choose between operation and projects, the best of both worlds. You see a lot, learn constantly, but without the stress of a classical consultant who starts from scratch with every new customer.

Projects (ca. 40%) – here you lead

You lead your own projects from start to finish. Not as a consultant who disappears after the concept, but with full implementation responsibility: You plan, you build, you hand over.

• Data center migrations: Location changes, colocation moves, hardware refreshes
• Platform modernizations: VMware-to-Proxmox migrations, storage upgrades, virtualization consolidations
• Resilience projects: Disaster recovery concepts, high availability, backup strategies
• Technical project leadership: You coordinate implementation, align with customers, hand over to operations teams

Mentoring by senior engineers, but you bear the responsibility. From the first year.

Operation (ca. 60%) – here you stay at the pulse

You operate the infrastructures we built. That keeps you technically sharp and shows you what really works in practice.

• Data center infrastructure: Windows Server, Active Directory, M365, Proxmox VE
• Virtualization & Storage: Proxmox VE, VMware, Ceph, performance optimization
• Backup & Recovery: Veeam Backup, restore tests, DR drills
• Monitoring & Incident Response: Prometheus, Grafana, troubleshooting
• Dokumentation: Runbooks, As-Built, knowledge transfer

No ticket-based work. You optimize, automate, make systems better.

Qualification

You bring this:

• 2-5 years of experience in system administration or comparable
• Fundamental knowledge: Windows Server, Active Directory, M365
• Experience with backup solutions (ideally Veeam)
• Basic understanding of network & security (VLANs, firewalls, VPNs)
• Structured work style, sense of responsibility, willingness to learn
• German conversation secure (C1/C2), English good

Nice-to-have:

Linux administration, storage systems (Ceph, NetApp), automation (Ansible, Terraform), monitoring (Prometheus, Grafana), certifications (Microsoft, VMware, Proxmox, Veeam).

Benefits

You will be really good

• 3,000 € training budget per year. You decide what you want to learn.
• Echtes Mentoring durch Senior Engineers, who have implemented over 200 data center projects: code reviews, architecture sessions, pair working. Not as a
