Develop engineering platforms and self-service capabilities that make the secure path the easiest path for developers. Lead the evolution of DevSecOps practices across cloud infrastructure, CI/CD pipelines and software delivery. Lead executive response during major security incidents whilst continuously improving cyber resilience and recovery capabilities. Ensure regulatory and compliance requirements are achieved through engineering excellence and automation wherever possible. Develop meaningful security metrics and executive reporting focused on organisational risk, engineering maturity and business outcomes. Build high-performing security teams through coaching, mentoring and technical leadership. Evaluate emerging technologies, AI capabilities and evolving threat landscapes to continuously strengthen the organisation's security posture.
