The company serves around six million customers and operates across 18 markets in Europe and North America, with its services being accessible worldwide. With its Web Presence & Productivity portfolio, IONOS acts as a 'one-stop shop' for all digitalization needs: from domains and web hosting to classic website builders and do-it-yourself solutions, from e-commerce to online marketing tools. In addition, the company offers Cloud Solutions to enterprises who are looking to move to the cloud as their businesses evolve.   


As a member of the multinational security management team at IONOS SE, you will be working for one of Europe's largest hosters in the rapidly growing cloud sector, contributing your knowledge and experience to better protect our products and system landscape. You will be responsible for the design and operation of an integrated management system that includes certified areas from ISO 27001, BSI IT-Grundschutz and BSI C5, among others, and is constantly being expanded. 

The aim is to motivate and control the implementation and operation of security mechanisms, not only to demonstrate that our products meet the security requirements of the standards, but also to increase the benefits for our customers and the company.

The creation of synergies through lean processes, the skilful use of tools and the efficient, redundancy-free planning and execution of audits are an important part of your duties.

  • You will assume the role of a specialist and be able to independently manage the implementation and design of the integrated management systems.
  • You will analyse our systems, processes and products against information security standards.
  • You will qualify and evaluate measures to meet security requirements and manage projects to implement them.

  • You have a degree in Computer Science or a comparable qualification, ideally with a specialisation in Information Security.
  • You have in-depth knowledge of compliance standards for cloud services and hosting providers in the European Union, e.g. BSI C5, BSI IT-Grundschutz, ISO 27001, GDPR, CSA CCM. Experience with industry and international regulations would be an advantage, e.g. HIPAA or BAIT/DORA.
  • You are passionate about technology and have experience of cloud services and the implications of shared ownership.
  • You are proactive, self-motivated and a good team player.
  • You have strong analytical and problem solving skills and are willing to take on challenges and explore different avenues to find practical and effective solutions.
  • You are quick to learn and can quickly familiarise yourself with new issues.
  • You are able to communicate proactively and confidently in German and English.
