We are seeking an experienced IT Infrastructure Security Engineer to help protect and strengthen enterprise technology environments. In this role, you will design, implement and maintain security controls across on-premises and cloud infrastructure, ensuring systems remain resilient, compliant and aligned with recognised security best practices. You will work closely with infrastructure, networking, development and service management teams to identify risks, improve defensive capabilities and support secure technology delivery.

Your responsibilities will include monitoring and responding to security events, investigating vulnerabilities, supporting patch and configuration management, and maintaining secure standards for servers, networks, endpoints, virtualisation platforms and cloud services. You will contribute to identity and access management, privileged access controls, encryption, firewall and intrusion prevention technologies, endpoint protection, vulnerability scanning and security logging. You will also assist with incident response, root-cause analysis, disaster recovery planning and the continuous improvement of security monitoring and operational procedures. Accurate documentation, risk reporting and evidence gathering for audits will be an important part of the role.

Applicants should have proven experience in infrastructure security engineering, systems administration, network security or a closely related discipline. Strong knowledge of operating system hardening, network protocols, cloud security principles, security information and event management tools, vulnerability management and common cybersecurity frameworks is required. Experience with scripting or automation, infrastructure-as-code, zero-trust concepts and security standards such as ISO 27001, NIST or CIS Controls would be advantageous. Relevant professional certifications are welcome. You should be analytical, methodical and confident communicating technical risks to both specialist and non-specialist audiences. The role requires a proactive approach, sound judgement, a commitment to continuous learning and the ability to manage competing priorities in a collaborative environment.
