Job description

I’m working with a leading quantitative technology firm that is looking to hire an experienced Network Engineer to work on a highly sophisticated, large-scale network environment.

This is not a traditional network support role. The focus is on network engineering, automation, observability and reliability, with ownership across the full network stack.

You’ll be working across Cisco and Arista infrastructure, while helping to improve how the network is monitored, automated and operated.

What You’ll Be Doing

• Own the reliability, performance, availability and security of network infrastructure
• Design and maintain large-scale datacentre networking across Cisco and Arista environments
• Develop network observability.
• Contribute to Infrastructure-as-Code and CI/CD practices for network provisioning
• Work across WAN connectivity, including MPLS and Segment Routing

What I’m Looking For

• Strong experience as a Network Engineer within an enterprise or large-scale environment
• Cisco and Arista networking experience, including IOS, IOS-XR, NX-OS and EOS
• Strong knowledge of BGP, OSPF, EVPN, VXLAN and MPLS
• Experience with network security infrastructure, including firewalls, IDS/IPS and segmentation
• Experience applying SRE, observability and automation principles to networking
• Python and/or Ansible experience, ideally alongside Jenkins, Git or IaC

Highly competitive base salary + annual discretionary bonus

The package also includes a strong benefits offering, including 30 days’ annual leave, 9% pension contribution, private healthcare and a number of additional lifestyle benefits.
