About the role

We are seeking a Senior Networking Engineer with deep expertise in data-center networking, routing, and high-throughput packet delivery to join our Operations team in Copenhagen, working side by side with our SRE team. This role involves owning the network fabric that underpins our backup infrastructure. From the physical and virtual topology inside our data centers to the edge and connectivity that carries billions of objects over foreign APIs and imperfect networks. You will define how traffic flows, how it stays reliable under load, and how it stays secure end to end. Technical ownership, a systematic approach to reliability, and strong initiative are essential for this role.

You will:

• Own and evolve our network architecture — data-center fabric, routing (BGP/OSPF), and segmentation.

• Design and operate load balancing, ingress, and traffic-management for a platform moving data at scale

• Define and enforce network reliability standards, runbooks, and change-management practices

• Build network automation and observability — treat the network as code, with visibility into every hop

• Manage VPN connectivity for management purposes to remote regions.

• Collaborate with SRE, Development, Operations and Security to identify and resolve bottlenecks and issues before they become incidents

• Champion automation — if something is done twice, it should be scripted the third time
  

About you

Must-haves:

• 5+ years in a Network Engineering, Network Reliability, or Infrastructure Engineering role

• Strong hands-on experience with routing and switching at scale (BGP, OSPF, VLANs, VXLAN/EVPN)

• Solid Linux networking fundamentals — the kernel network stack, iptables/nftables, tc, and comfort working close to the metal

• Experience with load balancing and reverse proxies (Nginx, HAProxy, or equivalent)

• Proactive mindset — you spot gaps before they become incidents

• Clear communicator; you can translate network decisions for engineers who don’t live in a terminal
  

Nice-to-haves:

• Network automation experience (Ansible, Terraform, or vendor APIs) and infrastructure-as-code practices

• Experience with Kubernetes networking (CNI, service mesh, ingress controllers)

• Familiarity with network observability and flow analysis (sFlow/NetFlow, eBPF-based tooling)

• Background in DDoS mitigation, firewalling, or network security at the perimeter

• Experience operating networks across multiple data centers or hybrid cloud environments
