Role:
Are you looking for a position where your architectural decisions form the backbone of entire networks? Here, as a Senior Firewall & VPN Engineer, you shape the technical future of service provider, data centre, and customer environments. The focus is on Multiprotocol Label Switching (MPLS), complex BGP designs, and well-thought-out firewall architectures. When there is a crisis, you are the technical authority in the team and find the cause. At the same time, you drive innovation forward and set standards for routing, switching, and security.
Responsibilities:
You are responsible for the architecture of the core, access, and security infrastructure and set binding technical standards.
You specifically develop complex Border Gateway Protocol (BGP) environments, peering concepts, and MPLS services on Layer 2 and 3.

Furthermore, you analyse traffic flows, latencies, and capacities and derive concrete optimisations from them.

You also manage network migrations and data centre connections and test new technologies in proofs of concept.
Qualifications:
You bring at least 5 years of practical experience in network and security engineering, preferably from a carrier environment.
You master routing policies, route selection, and route filtering and are familiar with service provider architectures with MPLS firsthand.
Switching topics such as link aggregation, VLAN, trunking, and STP/RSTP as well as TCP/IP with IPv6 and IPv4 are routine for you.
Moreover, you have solid experience with carrier and enterprise firewalls, ACLs, as well as remote access and site-to-site VPN.
You methodically detect faults, whether with Wireshark, routing tables, logs, or flow data.
Additionally, you have worked with solutions from Brocade, Cisco, Ruckus, Extreme, and/or Fortinet and recognise dependencies across all network layers.
