• Identify emerging threats and vulnerabilities using AI-driven threat intelligence and analysis, ensuring the right countermeasures and mitigations are prioritized and implemented through detection technologies and governance frameworks.
• Run an AI-powered vulnerability and patch management program, using AI agents to triage findings, assess exploitability, and draft remediation, maintaining a clear understanding of technical control measures.
• Design, build, and continuously improve AI-driven security workflows such as alert triage, automated compliance evidence collection, and third-party risk assessment.
• Provide subject matter expertise to internal stakeholders and collaborate with information security partners to stay ahead of industry technologies and evolving threats.
• Deliver the InfoSec technology roadmap, ensuring regulatory obligations are met in line with industry best practices.
• Shape ongoing cybersecurity strategy in an evolving digital landscape, including the secure adoption of AI across the organization.
• Define and review key security performance indicators and use AI tools to automate reporting for management updates and escalations.
• Build and maintain cybersecurity policies, procedures, and processes, using AI to draft them, map them against control frameworks, and keep them current.
• Continuously collect, correlate, and analyze security data with AI and automation to detect external and internal threats across services.
• Prepare the platform for Go Live, ensuring support processes are in place, rolled out to teams, and integrated with the wider parent group.
• Remove team impediments by working collaboratively with stakeholders to proactively manage risks, issues, or delays.
