The successful candidate will have proven experience translating security policies into practical technical controls, optimising complex firewall rulebases, and driving continuous improvement through automation and operational excellence. Strong communication and stakeholder management skills are essential, along with the ability to influence outcomes, challenge non-compliant designs, and provide pragmatic, risk-based solutions that support both security and business objectives.
