VIQU have partnered with a globally recognised energy trading organisation operating within a highly regulated, security-critical environment. With business-critical systems supporting international operations, cyber security is a core priority rather than an afterthought.

This role is heavily weighted towards security, with network responsibilities forming part of a wider cyber defence remit.

Key responsibilities include:

• Security monitoring, threat hunting and incident response
• SIEM, MDR oversight and vulnerability management
• Firewall, VPN, IDS/IPS and Zero Trust technologies
• Pen testing coordination and CVSS-led remediation
• Security architecture planning, policies and disaster recovery

• Networking: Cisco (Catalyst, Nexus), Fortinet, Firewalls and VPNs
• Security Ops: SIEM, intrusion detection, ethical hacking
• Scripting: PowerShell

• Proven experience in a security-focused infrastructure role
• Strong hands-on expertise with Firewalls, SIEM and threat detection
• Experience in regulated or high-risk environments (preferred)
• CCNA/CCNP or equivalent security certifications

This is an opportunity for a true security specialist to take ownership of protecting a complex, high-value environment while maintaining limited but meaningful network oversight.
