As an IT System Engineer, you will play a key role in operating, maintaining, and continuously improving modern IT infrastructure across multiple data center and office environments. You will be responsible for ensuring the reliability, availability, and security of physical and virtual server environments while supporting business-critical platforms and core IT services.
Your daily responsibilities will include managing Linux-based server infrastructure, operating Proxmox virtualization environments, and maintaining storage platforms such as Ceph and ZFS. You will provision, patch, and monitor servers, administer core infrastructure services including DNS, DHCP, NTP, backup, and disaster recovery solutions, and contribute to hardware lifecycle management across colocation facilities. In addition, you will support Microsoft 365, Microsoft Entra ID, Active Directory, and Exchange Online, while assisting with networking, VPN connectivity, firewalls, and general corporate IT infrastructure. You will work closely with infrastructure and network engineers on system improvements, automation initiatives, technical documentation, and incident management, while participating in an on-call rotation.
To succeed in this role, you have solid hands-on experience with Linux system administration, server infrastructure, and virtualization technologies such as Proxmox, VMware, or comparable platforms. You have a good understanding of storage technologies, backup and disaster recovery concepts, TCP/IP networking, and core infrastructure services. Experience with scripting languages such as Bash, PowerShell, or Python is considered an advantage, as is knowledge of Cisco networking, Palo Alto firewalls, Microsoft 365, Microsoft Entra ID, or Active Directory. You are analytical, proactive, and enjoy working in technically diverse environments where you can take ownership and solve complex infrastructure challenges. A background in IT infrastructure, systems engineering, or computer science is required. Fluent English is essential. Please note that applicants must hold Swiss or EU citizenship, as visa sponsorship cannot be provided for this position.
This is an excellent opportunity to join a technically focused engineering team where you will work across data center infrastructure, virtualization, enterprise systems, and corporate IT. You will benefit from a broad technical scope, the opportunity to further develop your expertise in systems engineering, networking, security, or platform technologies, and the chance to make a direct impact within a dynamic and growing international organization.
