Keywords: Network security, InfoSec, Cyber Security Engineer,
Are you a Network Security Engineer ready to step into a role where your expertise shapes the security of a modern, hybrid tech environment? This is your chance to own security tooling, influence design decisions, and help strengthen a growing cyber function.
What You’ll Be Doing
You’ll take the lead on securing complex enterprise networks across cloud and on‑prem environments, including:
Configuring and optimising security tooling such as segmentation platforms, Sophos, Mimecast, XDR solutions, vulnerability scanners and hardening baselines.
Managing firewalls, VPNs, secure remote access and segmentation controls.
Improving detection and response by working closely with SIEM/SOC teams.
Ensuring critical logging, monitoring and compliance standards are always met.
Automating deployments and controls using PowerShell, Python, Terraform or similar tools.
Supporting vulnerability assessments and driving remediation across the estate.
Contributing to secure design reviews across applications, infrastructure, and cloud services.
Incident response experience is desirable but not essential.
We’re looking for someone with:
Strong hands‑on experience with network infrastructure and security, segmentation, firewalls, endpoint security, XDR and access control.
Experience securing Cloud (Azure and/or AWS) and on-premise environments.
A security‑first mindset and confidence working with both technical and non‑technical stakeholders.
Knowledge of frameworks such as NIST, ISO 27001, CIS, GDPR would be preferred.
A proactive, accountable approach- you like owning outcomes.
Why This Role Stands Out
This isn’t just another security engineering job. It’s a chance to:
Take ownership of a modern security tooling ecosystem
Influence architectural decisions
Drive meaningful improvements across the whole tech estate
Work in a supportive, forward‑thinking security team
