Job Technologies

Your role in the team

  • In order for our research to be successful, we need IT that is as ambitious as our technology: secure, reliable, and ready to grow with our company.
  • We are rebuilding our IT infrastructure to a large extent. Together with our IT Lead, you will shape our infrastructure, processes, and security standards—with a high degree of responsibility and real creative freedom.
  • Therefore, we are not looking for someone who is limited to a narrow specialty, but rather a hands-on IT all-rounder with broad technical knowledge.
  • You enjoy solving problems holistically and like working in a team.
  • You operate and develop our hybrid IT landscape further - from cloud services and highly secure on-premise environments to servers, storage, networks, and end devices.
  • You design, operate, and secure our highly secure on-premise platform, particularly virtualization and storage clusters based on open-source technologies such as Proxmox VE and Ceph.
  • You establish pragmatic, well-documented IT processes—including asset and license management, patch and change management, backup and recovery, as well as onboarding and offboarding.
  • You support the development of our information security management system, aligned with standards such as ISO 27001 and TISAX, and implement technical security measures.
  • This includes, among other things, Identity & Access Management, hardening, network segmentation, logging, and vulnerability management.
  • Together with our external partners, you are responsible for the Microsoft stack.
  • You manage service providers around Microsoft 365, Entra ID, and Intune, ensure quality, and serve as the internal contact person.
  • You operate and integrate typical business applications such as ERP, CRM, and DMS systems as well as collaboration tools and incorporate them into our identity and security landscape.
  • You connect IT, research, and production, supporting laboratories and production-related systems together with our scientists and engineers — from measurement instruments and research software to IT/OT.
  • You automate recurring tasks with scripts and Infrastructure-as-Code and assist in the evaluation and operation of AI tools as well as local AI infrastructure.
  • You support and train our employees in a practical manner - especially when working in secure environments.

Our expectations of you

Education

  • A degree in computer science, business informatics, or a related field, or a completed apprenticeship, for example as an IT specialist for system integration — as well as several years of practical experience in system administration.

Qualifications

  • Extensive knowledge in the administration of Linux and Windows servers, virtualization, storage, networking, and end devices.
  • You are familiar with VLANs, firewalls, VPN, DNS/DHCP, WLAN, and Endpoint Management.
  • Good knowledge of the Microsoft ecosystem, especially Microsoft 365, Entra ID or Active Directory, Intune, and Exchange Online.
  • A strong security awareness and understanding of Least Privilege, Hardening, Backup Strategies, and Secure-by-Design.
  • Scripting skills in PowerShell, Bash, and/or Python.
  • An independent and structured way of working.
  • You enjoy documenting your solutions, building pragmatic processes, and communicating clearly with research, management, and external partners.
  • Excellent German and English language skills, both written and spoken.
  • A valid work permit for the European Union and a willingness to undergo a security clearance process.

Experience

  • Experience with Proxmox VE and/or Ceph – or solid knowledge in virtualization, for example with VMware or Hyper-V, and the motivation to learn new technologies.
  • Experience with common business applications and ideally initial exposure to research or production environments, such as laboratory IT, measurement systems, MES, LIMS, or ELN.
  • Genuine interest in AI and practical experience with AI tools - ideally also with the local deployment of models.

  • The opportunity to contribute to strengthening the semiconductor industry in Europe and to developing solutions for the challenges of climate change.
  • An environment with a technology and a product that can change the world.
