Responsibilities
As the central point of contact for the client, you take ownership of the core IT infrastructure.
System Administration (Hybrid): You are the expert for Windows and Linux server environments (operation, hardening, maintenance) and administer Windows clients as well as Linux systems for applications.
Network & Security: You design and operate networks (Dell OS10 switches: VLANs, routing, LACP) and manage SonicWall firewalls (VPNs, rule-set optimization, firmware updates).
Automation: You enjoy automating manual processes with PowerShell, Bash and/or Ansible to increase efficiency.
Cloud & Projects: You actively support exciting Microsoft-focused projects (M365, Entra ID / Azure AD, Defender, Sentinel, Azure networking services).
Requirements
Proven experience in both Windows and Linux administration (operation, hardening, package management).
Strong knowledge of network management (experience with Dell switches is a plus) and firewall administration (e.g., SonicWall).
Experience automating tasks using common scripting/automation tools (PowerShell, Bash or Ansible).
Good knowledge of Microsoft technologies (M365, Entra ID/Azure AD, Azure).
A proactive, solution-oriented mindset and the ability to take initiative and drive topics forward independently.
Benefits
Remote-first culture: Work flexibly from where you are most productive, with regular meetups in the Hamburg area.
Best of both worlds: Enjoy the stability and compelling projects of a large client combined with the agile culture and flat hierarchies of a small, experienced IT service provider.
