IT Infrastructure Platform Owner (m/f/d) 100%

About us:

mobilezone AG is in the midst of a technological transformation. Our IT platforms are the foundation for innovation, scalability and efficiency throughout the company. In this role, you take on the technical ownership of our central IT platforms and actively develop them further – with a strong focus on automation, AI-supported working methods and modern cloud architectures.

Your mission:

You are not an administrator, but a creator: You recognise potential, make technical decisions and implement them together with internal teams and partners.

Your tasks:

TECHNICAL OWNERSHIP – oversee & ensure

You maintain the technical overview of our entire infrastructure landscape and ensure that all systems are operated stably, securely and performantly
You identify technical risks, vulnerabilities and need for action – proactively, not only when there is a crisis
You are responsible for the technical operational quality in the areas of Azure Cloud, Microsoft 365, network, endpoint management and security services
You have the technical depth to intervene yourself in incidents if necessary

SERVICE OWNERSHIP – coordinate & drive forward

You are the technical interface to our managed service provider: you define what is needed, provide technical specifications and ensure that implementation is correct
You check whether what is delivered is technically correct, complete and sustainable
You know when to implement yourself and when to coordinate and delegate
You work closely with the CDIO, the IT team and external partners

FURTHER DEVELOPMENT – evaluate & shape

You continuously evaluate new technologies, tools and solution approaches and assess their benefits for mobilezone
You identify modernisation and consolidation potentials in the existing infrastructure and bring in concrete proposals
You develop decision bases and technical concepts – and accompany their implementation from idea to productive operation
You actively drive automation and efficiency improvements and ensure that technical decisions are documented and shared within the team

Your profile:

Completed studies in computer science, business informatics or comparable – alternatively convincing practical experience in the relevant field
Solid practical experience with Microsoft Azure (IaaS, Entra ID, Networking) and Microsoft 365 (Exchange Online, Teams, Intune)
Experience in operating hybrid and cloud-first infrastructure environments
Hands-on mentality combined with structured, independent working style
Fluent English or German skills

Nice to have:

Scripting skills for automation (PowerShell, Power Platform or comparable)
Experience with AI tools in everyday work (e.g. Copilot, ChatGPT) to support analysis, documentation or automation

We offer you:

State-of-the-art infrastructure in a central location
Flexible working hours including home office option
Appreciative atmosphere with flat hierarchies
Attractive occupational pension scheme benefits

Accident insurance in the private department
Employee offers in the telecommunications sector
Various employee events as well as other events
and much more...
