Network Security Engineer

Network Security Engineer - Global Tech Operations
Location: Basingstoke (Hybrid - 3 days per week on-site)
Salary: 50,000- 55,000 + excellent benefits

Join a business undergoing transformation, where you'll have the opportunity to shape how security and networking are delivered across a global, high-integrity environment. This is a great opportunity for an experienced Network Engineer with a strong troubleshooting mindset and a growing interest in cybersecurity tools and processes.

This isn't a rinse-and-repeat support desk role. You'll work on critical infrastructure, be trusted with important decisions, and have the chance to grow in both technical breadth and depth. With a new leadership team in place and investment in tooling underway, it's a great time to join.

What you'll be doing

You'll be supporting and improving complex networks and core infrastructure systems across a secure production environment. Day to day, you'll be configuring switches and firewalls, monitoring performance, investigating issues at network and transport layers, and helping maintain and evolve the organisation's security stack-including Defender XDR, SentinelOne, and iBoss. You'll work closely with infrastructure and security colleagues to help cross-train and provide joined-up support.

What you'll bring

• Strong hands-on experience with switching, firewalls, VPNs and WAN/LAN/WLAN support
• Knowledge of routing protocols (e.g., OSPF, BGP, RIP) and QoS techniques
• Experience with Cisco or HP networking tech (CLI preferred), plus Check Point or similar firewalls
• Familiarity with tools such as Microsoft Defender XDR, Sentinel, iBoss, Cisco ISE or Secure Access
• Awareness of vulnerability management, threat prevention, and SOC tooling
• Ability to investigate and troubleshoot under pressure with a methodical, root-cause approach
• Previous experience in an ITIL-aligned environment

Why this role?

• Be part of a newly integrated team where you'll gain exposure to both networking and security
• Work with a fantastic line manager and a team that values mutual learning
• Enjoy a varied, hands-on role with real autonomy-where your ideas for improvement will be heard
• Help support a transformation as the business invests in tooling, process and capability

You'll get 26 days' holiday, private health insurance, life cover, pension, flexible working (3 days onsite), and the opportunity to work in a collaborative, no-blame culture with global reach.

Due to the nature of the organisation, you will need to pass a security vetting process.
