Operational Technology Security Strategist

About Transgrid  

At Transgrid, we play a crucial role in delivering safe, reliable, and sustainable energy to millions of Australians. Operating over 13,000 km of high-voltage transmission lines and 134 substations across NSW and the ACT, we connect electricity generators to the distribution network powering homes, businesses, and communities. As Australia accelerates its energy transition, the work we do has never been more significant.

The opportunity

Power doesn’t just flow through transmission lines. It flows through the trust, resilience and expertise of the people who protect them. As Operational Technology Security Strategist, you will help protect the backbone of Australia’s power system while strengthening it for a new era of energy. You will shape lifecycle cyber security strategies for the digital infrastructure supporting Transgrid’s transmission network, including protection, control, metering, telecommunications and operational technology systems. Your work will help keep today’s network secure while building the resilience needed for what comes next.

The impact you’ll make

You will connect cyber security strategy with asset management, operational performance and investment planning across Transgrid’s OT environment by:

• Developing lifecycle cyber security strategies and plans for OT infrastructure in line with Transgrid’s Asset Management System.
• Embedding AESCSF, IEC 62443, NIST and ISMS requirements into OT asset design, risk management and lifecycle decisions.
• Assessing OT security asset condition, performance and risk to inform augmentation, replacement, maintenance and capital investment plans.
• Strengthening monitoring, incident readiness and cyber maturity through dashboards, standards, procedures and fit-for-purpose security tools.
• Partnering with operational teams, enterprise security, regulators and other stakeholders to deliver secure, practical and cost-effective outcomes.

What you’ll bring

You will bring practical OT cyber security expertise, strong analytical judgement and the ability to influence across technical, operational and executive stakeholders, supported by:

• At least 5 years’ experience across OT or industrial control systems, cyber risk assessment, security architecture, network security or technology security.
• Working knowledge of IEC 62443, NIST, ISMS and AESCSF, with experience translating security requirements into practical controls and plans.
• Knowledge of OT environments such as SCADA, protection and control IEDs, RTUs, metering, grid monitoring and telecommunications networks.
• Experience with OT security technologies, including intrusion detection, endpoint security, access management, SIEM, asset management and vulnerability scanning.
• Strong communication, consulting and stakeholder management skills, with relevant tertiary qualifications or certifications such as CISSP, GICSP or CISA viewed favourably.

Why this role

The energy transition does not happen in theory. It depends on secure, resilient infrastructure and the people who protect it. In this role, you will solve complex cyber security challenges across nationally significant operational technology assets, influencing policy, investment and decisions that will shape the network for decades. You will have real responsibility, visible impact and the opportunity to make critical infrastructure better, safer and ready for the future, working alongside Transgrid’s operational, engineering and security teams.
