Senior Network Security Engineer
Central Bristol (various hybrid working arrangements available depending on location).
£65,000 to £75,000 + bonus, 25 days holiday, good contributory pension
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.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
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.
