About the Cyber Security Officer at Infrastructure NSW
The Cyber Security Officer plays a critical role in safeguarding Infrastructure NSW’s digital environment and the broader ecosystem supporting key infrastructure projects. Operating within the ICT Security team, the position is responsible for monitoring and promoting compliance with NSW Government Cyber Security policies and procedures. That means translating policy intent into practical controls, supporting audits and assurance activities, and ensuring the agency’s systems and partners maintain a strong security posture in line with whole-of-government expectations.
Day-to-day, the role works closely with the Security Operations Centre (SOC) to identify, assess, and mitigate cyber risks. You will triage alerts, escalate incidents, and contribute to response coordination—while also helping to refine playbooks and strengthen detection and response capabilities. The operating environment is collaborative and dynamic: you will partner with ICT, business leads, vendors, and governance teams to balance operational needs with appropriate risk treatments. You will also support cyber reporting, assist with internal and external audits, and contribute to the periodic review and uplift of security policies.
Key challenges include keeping pace with evolving threats, enabling secure transformation of cloud and hybrid services, and ensuring consistent alignment with frameworks such as ISO 27001 and the Essential 8. As Infrastructure NSW advances its digital services to support critical projects, the Cyber Security Officer must anticipate and mitigate risks across platforms such as Windows, networking, firewalls, and cloud. The role requires both technical breadth and policy literacy: one moment you may be reviewing a risk register or audit finding, and the next you may be supporting an incident response activity with the SOC or validating remediation evidence for a vulnerability management cycle.
Success in this role looks like measurable improvements in incident preparedness, timely and accurate reporting, and demonstrable compliance with NSW Government standards. If you are scanning for cyber security jobs NSW where your work tangibly improves resilience of public services, the Cyber Security Officer at Infrastructure NSW offers significant scope to contribute.

Enjoy hybrid and flexible working options and a modern workplace located near Wynyard station in Barangaroo, Sydney. The inclusive culture supports growth and professional development, and a talent pool may be created for future vacancies, broadening your career opportunities across the sector.
As far as cyber security jobs NSW go, this is a well-rounded role that blends policy, operations, and continuous improvement.

Cyber Security Officer Example Cover Letter
Dear Hiring Manager,
I am writing to apply for the Cyber Security Officer (CL 0708) position with Infrastructure NSW. As a Senior Security Analyst at DataSphere Solutions, I have developed a proven record of strengthening cyber resilience across complex, multi-cloud environments. My experience aligns strongly with your requirements, combining technical depth, framework-based governance, and a pragmatic approach to security uplift that supports business priorities and service continuity.
My tertiary qualifications in Information Technology, complemented by extensive experience in cyber security operations, have enabled me to apply and embed recognised frameworks including ISO 27001 and the Essential 8 across enterprise environments. At DataSphere, I led the maturity uplift of our vulnerability management program, aligning remediation processes with ISO 27001 control requirements. By mapping identified vulnerabilities to control gaps and establishing clear remediation timelines, I achieved a 30% improvement in audit compliance within six months. This initiative not only reduced operational risk but also demonstrated my ability to interpret standards and translate them into actionable, measurable improvements.
With a broad technical knowledge of Windows, networking, firewalls, and cloud technologies, I bring hands-on expertise in identifying and mitigating cyber risks across diverse platforms. In a recent project, I coordinated a cross-functional team spanning DevOps, network engineering, and application support to assess and harden cloud configurations against evolving threats. By implementing automated compliance checks and network segmentation controls, we reduced exposed attack surfaces by 40% while maintaining system performance and availability. This experience reflects my ability to bridge technical and operational domains to achieve secure, sustainable outcomes.
My background includes leading multiple vulnerability management and incident response initiatives across hybrid and multi-cloud environments. During an enterprise-wide incident response exercise, I coordinated simulation activities involving both internal teams and external partners. I developed scenario playbooks, facilitated root cause analysis, and delivered executive summaries highlighting readiness gaps and priority actions. The exercise improved organisational preparedness and reinforced a culture of proactive risk management, demonstrating my ability to deliver structured, results-driven security programs aligned with business needs.
A key strength I offer is the ability to engage stakeholders effectively at all levels. I excel at translating complex security risks into clear, actionable decisions, ensuring that technical findings are understood in their business context. For example, when presenting vulnerability trends to senior management, I developed dashboards that visualised risk by business impact rather than technical severity. This approach improved decision-making on resource prioritisation and remediation sequencing, directly aligning with organisational objectives.

At DataSphere, I led initiatives that delivered measurable improvements in control effectiveness and compliance. I designed and executed a risk-based remediation plan that integrated patching, configuration management, and continuous monitoring. This approach reduced critical vulnerabilities by 45% and established a sustainable process for ongoing risk management. My background also includes coordinating incident response activities, developing runbooks, and conducting post-incident reviews that strengthen resilience and readiness. Together, these experiences demonstrate my alignment with INSW’s focus on proactive, structured, and standards-based security operations.
