  • Permanent
  • Discipline: Cyber Security
  • Ref: 51078

As a Network & Security Engineer, you will play a key role in designing, operating, and securing modern enterprise and data centre network infrastructures across multiple locations. You will be responsible for ensuring reliable, secure, and high-performing connectivity by managing switching, routing, firewalls, VPNs, internet connectivity, and network services while supporting business-critical infrastructure and telecommunications platforms.

Your daily responsibilities will include configuring and maintaining Cisco-based network environments, managing enterprise firewall solutions, operating site-to-site and remote-access VPNs, and supporting internet edge connectivity and BGP routing. You will monitor network performance, troubleshoot complex connectivity issues, analyse network traffic using Wireshark, and implement network segmentation, infrastructure hardening, and security best practices. In addition, you will contribute to infrastructure lifecycle projects, maintain technical documentation, support Linux-based infrastructure services, and assist with data centre and colocation environments. Exposure to telecommunications protocols such as SMPP, SCTP, or SS7/SIGTRAN is considered a plus.

To succeed in this role, you have solid hands-on experience with TCP/IP networking, Ethernet, VLANs, routing, switching, VPN technologies, NAT, and enterprise network security. Experience with Cisco networking equipment is expected, while knowledge of Palo Alto firewalls, BGP routing, Proxmox, virtualization technologies, or storage platforms such as Ceph and ZFS would be highly beneficial. You are analytical, solution-oriented, and enjoy troubleshooting complex technical environments. Strong communication skills, a collaborative mindset, and the ability to take ownership of your work are essential. A background in IT infrastructure, networking, cybersecurity, or computer science, combined with fluent English, is required. German is an advantage, and you should already be resident in Switzerland.

This is an excellent opportunity to join a technically focused engineering team where you will work with modern networking, security, and telecommunications technologies. You will benefit from a broad technical scope, the opportunity to further develop your expertise in network architecture and cybersecurity, and the chance to make a direct impact within a dynamic and growing international organization.
