Cyber Security Analyst

Cyber Security Analyst - Permanent - Hybrid (2x a week in office)

We are working with a leader in the UK’s critical energy infrastructure sector, supporting the delivery of essential services to millions of customers nationwide.

They are seeking a technically strong Cyber Security Analyst to strengthen their network and infrastructure security capability.

This is not a SOC or shift-based monitoring role. The focus is on improving security architecture, hardening infrastructure, and embedding secure-by-design principles across network and cloud environments.

This role would suit someone with a background in network or infrastructure engineering who has transitioned into security and is looking to deepen their technical impact within a complex, operationally significant environment.

Key Responsibilities

• Design, review, and enhance network security architecture, including firewalls, segmentation, and secure connectivity
• Conduct technical security assessments across on-premise and cloud environments
• Lead vulnerability management activities, including prioritisation and remediation oversight
• Harden servers, endpoints, and infrastructure platforms in line with best practice
• Review and optimise security configurations across network and cloud technologies
• Support secure deployment of new infrastructure and systems
• Contribute to security standards, baselines, and technical documentation
• Partner with IT and engineering teams to improve resilience and reduce risk

Required Experience

• Strong background in network and infrastructure security
• Deep understanding of TCP/IP, DNS, VPNs, routing, switching, and firewall technologies
• Hands-on experience with vulnerability management tools
• Experience securing Azure, AWS, or GCP environments
• Familiarity with endpoint protection and infrastructure hardening
• Working knowledge of recognised security frameworks (e.g. ISO 27001, NIST, CIS Controls)

Interviews will commence swiftly.
