Job Cyber Security Lead | Critical Infrastructure & Converged OT (Contract starting Jan), Perth

Job Description

This is an opportunity to secure the digital and physical perimeter of a major critical infrastructure precinct. As our Cyber Security Lead, you will answer the "Challenge Us" mandate by defining the security posture for a converged environment where Operational Technology (OT), Enterprise IT, and Public-Facing Digital Platforms intersect. You will be architecting the defence of a city-scale ecosystem that spans Site-wide SCADA and Autonomous Infrastructure through to Customer Identity (CIAM) and Mobile Applications.

Your mission is to ensure trust in a highly connected environment. You will lead the security strategy for complex integrations, ensuring that Private 5G networks and LoRaWAN sensor grids are hardened against intrusion, and that the data flowing from Logistics Screening and Video Analytics systems remains secure. You will oversee the deployment of Cloud Access Security Brokers (CASB) to protect data moving between on-premise Electronic Access Control systems and cloud-based Technology Operations Platforms. Working alongside the Application Architect, you will enforce a "Security by Design" culture, ensuring that new innovations—like Digital Concierges or Virtual Queuing—do not introduce vulnerabilities into the critical operational network.
