The Cyber Security Engineer role

You’ll also do system hardening across Windows, Linux and cloud platforms (Azure/AWS).
Vulnerability management: handle vulnerability scanning, triage, risk-based remediation, patch management, fix validation and security exceptions across IT and OT.
Incident response: be the local technical contact for SOC/CERT, covering security incident investigation, containment, recovery, lessons learned and cyber incident exercises.
OT / ICS / SCADA security: work on IT/OT segregation, OT network segmentation, secure remote access, legacy system risk, OT asset visibility and OT monitoring, aligned to IEC 62443 and the NCSC CAF.
Security architecture: provide secure-by-design input, security design reviews, technical security assessments and risk treatment recommendations.
Governance, risk and compliance (GRC): maintain risk registers, support security audits and assurance, and contribute to security baselines, ISO 27001 controls and UK NIS regulations compliance.
