Phillip Grasso-Nguyen is Head of Engineering Excellence and Reliability at Macquarie Group, overseeing reliability across the banking division. Having previously worked at Google and served as an engineering lead at CBA, Phillip introduces tech-industry practices into a large-scale financial environment through site reliability engineering.

Supporting a digital bank of more than 6,000 services and 1,500 engineers, the programme prioritises smaller, frequent releases to limit the potential impact of failures. Automated checks of new code, AI-assisted incident investigation with human guidance, and shared operational visibility link software quality directly to everyday banking services, from account logins to payments.

Speaking at Dynatrace Perform 2026, Phillip highlighted organisation-wide outcomes including 99.98 per cent availability and reliability alongside a 59 per cent reduction in critical incidents.
