• Standards and assurance: Translate IEC 62443, CLC/TS 50701, NIST, and ISO requirements into practical controls. Maintain traceability from requirements and risk assessments through architecture, implementation, testing, and assurance evidence.
• Testing and commissioning: Define and execute security FAT and SAT activities, hardening and configuration checks, functional control tests, and integration tests with OT subsystems. Support vulnerability reviews, remediation, Security Case inputs, and operational acceptance.
• Technical coordination: Coordinate with OT, network, systems, SOC, vendor, and systems-integration teams. Plan technical work, manage dependencies and interfaces, identify delivery risks, and provide clear progress reporting.
• Regulatory alignment and leadership: Adapt designs to Australian critical-infrastructure, cybersecurity, data‑protection, and logging obligations while preserving reusable architectural principles. Mentor engineers and influence multidisciplinary design decisions.
