Deep AI background is not required; knowledge of AI/Agentic AI is an

advantage.

• Strong understanding of SOC operations and the ability to analyze and standardize security processes into workflows and decision frameworks.

• Ability to make decisions based on evidence and risk.
• Ability to clearly document business requirements and technical specifications.
• Strong communication and ability to work with multiple teams, including Security, AI, Software Engineering, and Product/Service Owners.
