Job description

Location: London / Hybrid

Type: Permanent

Salary: Competitive, dependent on experience

A leading global asset manager is seeking a hands-on Network Engineer to join its infrastructure team. This is a broad and varied role covering the design, build, operation, and automation of enterprise WAN, LAN, and voice networks across a global estate.

The successful candidate will work across core networking, campus and branch infrastructure, SD-WAN, voice platforms, and cloud connectivity. They will also play a key part in improving operational efficiency through automation, infrastructure-as-code, and modern DevOps practices.

What the role involves

• Design, deploy, support, and optimise enterprise WAN and LAN infrastructure across global offices and data centres.
• Work with routing and switching technologies, including BGP, OSPF, VLANs, STP, QoS, and VPNs.
• Build and maintain SD-WAN, internet breakout, cloud connectivity, and secure remote-access solutions.
• Support enterprise voice and collaboration platforms, including SIP, unified communications, contact-centre technologies, and voice network design.
• Troubleshoot complex production issues across network, security, voice, and application-delivery layers.
• Contribute to network architecture, capacity planning, resilience, and lifecycle-refresh projects.
• Automate repetitive operational tasks using Python, APIs, Ansible, Terraform, or similar tooling.
• Work with monitoring and observability platforms to improve visibility, alerting, and incident response.
• Collaborate with infrastructure, security, cloud, and application teams in an Agile, DevOps-led environment.
• Participate in an on-call rotation and support business-critical systems where required.

What we are looking for

• Strong enterprise networking experience across WAN, LAN, routing, switching, and firewall technologies.
• Solid knowledge of BGP, OSPF, VPNs, QoS, DNS, DHCP, and network security principles.
• Experience with SD-WAN, cloud networking, or multi-site enterprise environments.
• Exposure to enterprise voice, SIP, unified communications, or contact-centre platforms.
• A genuine interest in automation and DevOps, with skills in Python and/or infrastructure-as-code tools such as Ansible or Terraform.
• Experience with network monitoring, logging, and observability tools.
• Strong troubleshooting skills and the ability to work calmly under pressure.
• Excellent communication skills, with the ability to work effectively with technical and non-technical stakeholders.
• Cisco, Juniper, Arista, Palo Alto, Fortinet, or equivalent technologies.
• Cisco Meraki, Cisco Catalyst/SD-WAN, or similar platforms.
• Microsoft Teams Voice, Zoom Phone, Avaya, Genesys, or other enterprise voice platforms.
• CI/CD, Git, Linux, and container-based tooling.
• Financial services, asset management, or other regulated-environment experience.

This is an excellent opportunity for a Network Engineer who wants genuine variety across WAN, LAN, voice, security, and cloud, while developing automation and DevOps capabilities. The successful candidate will join a collaborative engineering team with real ownership of critical infrastructure and the opportunity to influence how the network estate evolves.
