Setting the Scene
Our client is part of a global portfolio of specialised software businesses operating across Australia, the UK, Canada and the US.

They are seeking a Senior Security Advisor who can combine strong technical security capability with genuine GRC expertise and, importantly, an advisory mindset. This is a role where influence matters more than authority — you'll help businesses understand risk, develop practical controls and improve their security posture without taking a one‐size‐fits‐all approach.

Provide security architecture and engineering guidance across cloud, network, identity, endpoint and application environments
Translate security risks into practical, proportionate controls and technical solutions

Support GRC activities aligned to NIST, ISO *****, SOC 2 and relevant international requirements
Conduct vendor and third‐party security risk assessments
Improve security reporting, processes and compliance automation
Support newly acquired businesses in developing and integrating appropriate security practices
Provide detailed security insights and reporting to support senior leadership and board‐level reporting
Build strong relationships across the portfolio and influence security outcomes without relying on formal authority
