You will work closely with infrastructure, applications, risk, compliance, and business teams to strengthen security controls and promote a resilient security culture.

Your responsibilities will include analysing alerts from security monitoring platforms, conducting investigations, identifying root causes, and documenting incidents through to resolution.
