IT Infrastructure Engineer responsible for managing and enhancing IT infrastructure for a key client. Working in a hybrid model, focusing on Windows and Linux administration, networking, and automation.
Responsibilities
As the central point of contact at the client, you take responsibility for the core of the IT infrastructure.
System Administration (hybrid): You are the specialist for the Windows and Linux server landscapes (operation, hardening, maintenance) and administer Windows clients as well as Linux systems for applications.
Network & Security: You design and operate networks (Dell OS10 switches: VLAN, routing, LACP) and manage SonicWall firewalls (VPN, rule-set optimization, firmware).
Automation: You enjoy automating manual processes with PowerShell, Bash and/or Ansible to increase efficiency.
Cloud & Projects: You actively support exciting Microsoft technology projects (M365, Entra ID / Azure AD, Defender/Sentinel, Azure networking services).
Requirements
Solid experience in both Windows AND Linux administration (operation, hardening, package management).
Strong knowledge of network management (ideally with Dell switches) and experience working with firewalls (e.g., SonicWall).
Experience in automation with common scripting languages (PowerShell, Bash or Ansible).
Good knowledge of Microsoft technologies (M365, Entra ID, Azure).
A proactive, solution-oriented working style and the ability to drive initiatives independently.
Remote-first culture: Work flexibly from where you are most productive, with regular meetings in the Hamburg area.
Best of both worlds: Enjoy the stability and interesting projects of a large client, embedded in the agile culture and flat hierarchies of a small, experienced IT service provider.
Top equipment: You will receive a complete, high-quality setup for your home office.
Learning culture: Benefit from a wide range of learning and development opportunities to stay current with technology.
Security & provisions: 30 days of vacation per year and a company pension scheme (bAV) are standard.
