Run recurring operational tasks (access reviews, configuration reviews, logical and physical access controls…) in direct collaboration with application and system owners. Manage penetration tests and the exploitation of their results. Lead management reviews and continuous improvement loops. Engage the company and collaborate cross-functionally Translate security topics for non-technical audiences (Sales, Marketing, Finance, HR).
