Job description

The Cyber Security Engineer will help protect and improve security across a hybrid IT environment, spanning Microsoft Azure cloud services, on-prem VMware infrastructure, and the network estate (including Cisco Meraki). The role is hands-on and operational, partnering with IT teams to implement security controls, support monitoring and incident response through Sophos MDR, and improve cyber resilience by supporting Disaster Recovery (DR) testing and Business Continuity (BC) readiness., Cloud Security (Azure)

·Implement and maintain Azure security controls across identity, networking, compute and storage.

·Support governance guardrails (Azure Policy), secure baselines and logging/monitoring for cloud workloads.

·Contribute to security design reviews for new services and changes to ensure secure-by-default patterns.

On-Prem Security (VMware)
