Central Bristol (various hybrid working arrangements available depending on location). 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
  • Drive meaningful improvements across the whole tech estate
