Job description

We are seeking an experienced Network & Telephony Engineer to join a well‑established organisation with a complex, multi-site technology environment.

This is an excellent opportunity to work alongside a highly skilled engineering team, supporting critical network infrastructure while contributing to a strong pipeline of upcoming technology and infrastructure projects.

The environment is diverse, combining enterprise networking, security, wireless, telephony and cloud technologies. The role offers a good balance of hands‑on engineering, operational support and project delivery.

Key Responsibilities

• Design, implement, maintain and optimise enterprise network infrastructure across multiple sites.


• Support LAN, WAN, wireless, firewall and telephony environments.


• Troubleshoot complex network issues, undertake root cause analysis and act as a senior escalation point.


• Manage network security, including firewalls, access controls and network segmentation.


• Work closely with other engineers on network upgrades, improvements and future infrastructure projects.


• Monitor network performance, reliability and availability.


• Maintain network documentation, configurations and operational standards.

About You

We are particularly interested in engineers who have worked in large, complex, multi-site environments and understand the challenges of managing enterprise network infrastructure.

Ideally, you will bring:

• 5+ years' experience in network engineering or network operations.


• Strong technical knowledge of enterprise LAN/WAN, routing, switching and wireless networks.


• Experience managing firewalls, network security and segmentation.


• Exposure to telephony solutions, ideally Microsoft Teams Telephony.


• Experience supporting hybrid cloud and on‑premises environments.


• Strong troubleshooting skills and the ability to resolve complex technical issues.


• Excellent communication skills and a collaborative approach to engineering.

Technology background: The current environment includes HPE Aruba and Palo Alto, however, we are not wedded to these technologies. We are equally interested in engineers with experience across other enterprise networking and security platforms.

What matters most is your experience operating within complex, large-scale environments, your technical fundamentals and your ability to contribute to a strong engineering team.

Why Consider This Role?

• Complex environment: Work across a sizeable, multi-site network infrastructure with a broad range of technologies.


• Great engineering team: Join experienced engineers who collaborate, share knowledge and support one another.


• Future projects: Be involved in an exciting pipeline of network, infrastructure and technology initiatives.


• Technical variety: Gain exposure to networking, security, cloud and telephony rather than being limited to one technology area.


• Long‑term opportunity: Contribute to the ongoing development and improvement of a critical technology environment.
