Your role in the team

  • You are the owner of our entire IT infrastructure - on-premises, in our co-located data center, and in the cloud - and shape it to enable our company to further grow and succeed.
  • You manage our hardware infrastructure and office IT, including servers, workstations, notebooks, and networking.
  • This is a senior, hands-on role: you design and improve our infrastructure, and you carry out the technical work yourself.
  • Design, implement, operate, and maintain infrastructure across on-premises environments, our co-located data center racks, and cloud services, including Microsoft 365.
  • Manage the lifecycle of servers, storage systems, networking equipment, workstations, and notebooks, including provisioning, maintenance, upgrades, and decommissioning.
  • Monitor system availability, capacity, and performance, particularly across network and storage infrastructure.
  • Troubleshoot issues, identify bottlenecks, and implement improvements.
  • Design and maintain identity, authentication, authorization, group membership, and access provisioning processes.
  • Automate infrastructure provisioning, configuration, and maintenance using infrastructure-as-code and configuration-management tools such as Terraform/OpenTofu and Ansible.
  • Develop scripts and small internal tools or services to automate recurring tasks, integrate systems, and improve operational workflows.
  • Define and implement infrastructure security controls, backup and recovery procedures, and measures to maintain service availability and data integrity.
  • Automate workstation provisioning and configuration, manage endpoint software and settings, and provide hands-on support for office IT issues.
  • When something needs to be implemented or fixed, you take care of it directly.

Our expectations of you

Qualifications

  • Strong Linux administration skills, including troubleshooting and maintaining production systems.
  • Solid knowledge of network architecture and administration, including VLANs, firewalls, routing, and VPN technologies such as WireGuard.
  • A sound understanding of identity and access management, backup and recovery, and infrastructure hardening.
  • A hands-on, independent, and structured way of working, with the ability to take ownership of the full lifecycle of infrastructure topics.
  • Proficient in English and at least B2 level in German.
  • Based in Munich or the surrounding area, with the ability to attend the office at short notice when on-site support is required.

Experience

  • At least five years of relevant professional experience in systems administration, IT infrastructure engineering, or a comparable role.
  • Practical experience with container technologies such as Docker or Podman.
  • Experience with infrastructure as code and configuration management, for example Ansible or Terraform/OpenTofu.
  • Experience designing, implementing, and operating on-premises infrastructure and cloud services, including appropriate security controls.
  • Experience with SaaS infrastructure, such as Microsoft 365, is a plus.

What we offer

  • Technology that matters: Your work provides the reliable infrastructure behind software that enables innovation in medical imaging and helps bring cutting-edge research into clinical practice.
  • Ownership instead of micromanagement: Shape our IT infrastructure and standards, take responsibility for improvements, and put your ideas into practice yourself.
  • Short decision-making paths: We work pragmatically, collaboratively, and without unnecessary bureaucracy.
  • Flexibility: Flexible working hours and a hybrid work model allow you to balance remote work with the on-site support required for this role.
  • A team that supports each other: Join a collaborative, open-minded team where people enjoy working together and helping one another succeed.
