Senior Network Engineer – Datacenter & Cloud Networking

• Design, build and operate datacenter network infrastructure.

• Develop the network architecture for 1984's new public cloud.

• Design and operate EVPN / VXLAN environments.

• Operate BGP and Internet connectivity.

• Develop routing policies and network resiliency.

• Integrate Linux hosts and virtualisation platforms with the physical network.

• Build and operate high-speed networks for compute and distributed storage.

• Diagnose and resolve complex network incidents.

• Analyse network traffic and performance.

• Test convergence and failure scenarios.

• Improve redundancy and high availability.

• Automate network configuration and deployment.

• Build and improve network monitoring and alerting.

• Work with transit providers, datacenters and equipment vendors.

• Participate in capacity planning.

• Contribute to DDoS protection and mitigation architecture.

• Work closely with Linux, storage and software engineers.

• Document network architecture, configurations and operational procedures.

We are primarily looking for substantial hands-on experience designing and operating production networks.

Strong knowledge and practical experience with:

• BGP.

• IPv4 and IPv6.

• Ethernet switching.

• VLANs.

• Routing and routing policy.

• Linux networking.

• Datacenter network architecture.

• Network troubleshooting and packet analysis.

• Redundancy and high availability.

• Network monitoring and observability.

For our cloud environment, experience with the following is particularly valuable:

• EVPN / VXLAN.

• FRRouting / FRR.

• Zebra.

• BGP unnumbered.

• VRFs.

• Overlay and underlay network design.

• Leaf-spine architectures.

• ECMP.

• Anycast.

• Linux bridges and network namespaces.

Experience with some of the following is highly desirable:

• Juniper / Junos.

• NVIDIA / Mellanox Ethernet switching.

• Lenovo datacenter switches.

• High-speed Ethernet, including 100/200 GbE.

• MLAG.

• LACP.

• BFD.

• QoS.

• DDoS mitigation.

• Internet transit and peering.

• RIPE and IP resource management.

• DNS.

• KVM networking.

• Kubernetes networking.

• Apache CloudStack networking.

• Ceph networking.

• Network automation.

• Ansible.

• Python.

• Shell scripting.

• Netlink and eBPF.

We do not expect candidates to have worked with every vendor or technology listed above.

A candidate with strong experience operating large-scale Cisco, Arista or other vendor environments may be a very good fit even without direct experience with all of the equipment we currently use.

What matters most is a deep understanding of networking, strong troubleshooting ability and experience operating production infrastructure.

Formal education and certifications such as JNCIP, JNCIE, CCNP or CCIE are useful, but they are not requirements. Practical experience and technical depth matter more.

• Contribution towards fitness and exercise expenses.

• Contribution towards lunch costs.

• Flexible remote-working policy.

• The opportunity to help build a new Icelandic public cloud from the ground up.

• Significant technical independence and real influence over network architecture.

• Work with large and technically demanding production infrastructure.

• Direct involvement with physical networking, Linux, virtualisation and distributed storage.

• A role where technical depth and sound engineering matter more than buzzwords.

• A flexible and informal working environment.

• The opportunity to work with an experienced infrastructure team.

Our environment includes technologies such as:

• FRRouting / FRR.

• Zebra.

• BGP.

• EVPN / VXLAN.

• IPv4 and IPv6.

• Juniper / Junos.

• NVIDIA / Mellanox networking.

• Lenovo datacenter switches.

• Linux networking.

• KVM / QEMU.

• Apache CloudStack.

• Ceph.

• Kubernetes.

• Ansible.

• Python.

• Shell scripting.

• Prometheus / Grafana.

• High-speed Ethernet.

• Internet transit and peering.

• DDoS mitigation infrastructure.

• Distributed infrastructure across multiple datacenters.
