Security Operations & Incident Response: Mature and lead detection, analysis, and containment capabilities, driving post-incident remediation and preventative measures.
AI-Driven Security Transformation: Spearhead the evaluation, prototyping, and deployment of agentic AI patterns to automate security tasks, enhance threat detection, and transform engineering throughput. Build and refine AI agents to augment the security team’s capabilities.
Tooling & Automation Mastery: Take ownership of the security tooling lifecycle, from evaluation and deployment to configuration and continuous maturity across infrastructure.
Secure Onboarding & Assurance: Perform technical deep-dive security reviews for new applications, development stacks, and infrastructure changes, enforcing the principle of least privilege.

A seasoned practitioner: With demonstrable, hands-on experience across Security Operations, Incident Response, and Security Engineering.
An AI-forward builder: With a strong technical perspective on how agentic patterns, machine learning, and human-in-the-loop design can transform security engineering practices, alongside a genuine passion for building AI-powered security solutions.
A systems thinker and standardiser: Applying a holistic, system-level approach to security challenges, standardising processes and technology where it adds maximum value while enabling autonomy for development teams.
A technical doer and transformer: Comfortable working directly with code and infrastructure, eager to learn new technologies, and committed to challenging the status quo to drive meaningful change.
Resilient and adaptable: Thriving in high-intensity, demanding environments where expectations are high and pace is fast.
Cloud-agnostic: Bringing extensive experience securing complex, distributed multi-cloud environments (e.g., AWS, GCP, Azure).
