• Build, develop and maintain Cyber Security policies, procedures and processes, using AI to draft them, map them against control frameworks and keep them current.
• Optimise tools and processes, including AI agents and automation, that prepare Fintech to respond to security threats of the future.
• Ensure information and security data is continuously collected, correlated and analysed, using AI and automation, to detect external and internal threats and vulnerabilities to our services.
• Design, build and continuously improve AI-driven security workflows, such as alert triage, automated compliance evidence collection and third-party risk assessment.
• Prepare Fintech ready for Go Live, ensuring support processes are in place and rolled out to teams along with integration into the wider N Brown Group.
• Use AI tools to automate the creation of reports for management updates and escalations using key program performance metrics.
• Define and review key security performance indicators that ensure service delivery and service improvements.
• To manage and oversee an appropriate programme of vulnerability and patch management, using AI agents to triage findings, assess exploitability and draft remediation, to maintain an informed understanding of our technical control measures.
• To help shape and inform ongoing cyber security strategy in an ever-changing digital landscape, including the secure adoption of AI across Castle.
• To deliver the InfoSec technology roadmap into the business, ensuring our regulatory obligations are met in line with industry best practice.

Your Experience & Education Requirements:

• Demonstrable experience of using AI tools and agents (e.g. Claude, Microsoft Security Copilot or similar) to perform security work such as threat analysis, vulnerability triage, policy drafting and reporting.
• Good working knowledge of AWS security services and implementations, e.g. Security Hub, Control Tower, Organizations, SCPs, IAM entities and policies, Account lockdown and AI/ML tools like Macie and Guard Duty.
