The role focuses on architecting and optimising security tooling across the organisation, including endpoint protection, IAM/PAM, cloud security, SIEM, vulnerability management, and data protection solutions. It also involves evaluating new products through technical assessments and POCs, integrating tools across infrastructure and cloud environments, defining security standards and best practices, and collaborating with engineering, infrastructure, compliance, and incident response teams to improve visibility, detection, and operational effectiveness.
