Senior Security Analyst | 2-Year Fixed Term Contract | Melbourne

Are you a cyber all-rounder who enjoys variety and wants hands-on exposure across cloud, data centre and enterprise environments? Or are you an analyst ready to move closer to engineering work? This role gives you both: broad technical scope now, and a transparent runway towards a future Cyber Engineer career.

The Opportunity

Our client is a large, well-known Australian critical infrastructure organisation in the middle of a significant cyber transformation program. They're looking for a Senior Security Analyst to join the program team on a 2-year FTC, helping strengthen their security posture across enterprise IT, cloud platforms (Azure and AWS) and a secure data centre environment.

A major focus of the program is uplifting defences against emerging AI-driven threats. That means you'll be working on genuinely current problems, like automated attack chains and AI-enabled adversary behaviour, rather than just maintaining the status quo.

What You’ll Be Doing

- Build, configure and maintain security tools across IT, cloud and data centre environments
- Enhance SIEM, EDR and monitoring to detect anomalies and AI-enabled threats
- Turn threat intelligence into detection rules, dashboards and automated responses
- Run vulnerability scans and drive remediation with infrastructure and app teams
- Secure Azure and AWS environments (IAM, workload protection, logging)
- Apply hardening baselines to servers, endpoints and cloud workloads
- Support access control, monitoring and data protection in a secure data centre




- Support incident investigation, containment and recovery
- Improve tooling and workflows, and maintain runbooks and documentation
- Partner with IT, Cloud, DevOps, data centre ops, Risk & Compliance and vendors

About You

- Strong grounding in networking, operating systems and security fundamentals
- Hands-on with SIEM, EDR, firewalls, vulnerability scanners or cloud-native security tools
- Familiar with incident triage, investigation and containment
- Understanding of ISO 27001, NIST CSF and the Essential Eight
- Interest in AI-enabled threats and how to defend against them
- Data centre or sensitive data zone experience (highly regarded)
- Collaborative communicator with both technical and non-technical people
- Degree in Cyber, IT or Computer Science (desirable)
- Certs such as Security , CEH, AZ-500, AWS Security Specialty or CISSP (advantageous)

You don’t need to tick every box. Broad cyber generalists and strong analysts keen to move into engineering are encouraged to apply.

Why Apply?

- Up to $190K including Super (dependent on experience)
- Broad, hands-on exposure across enterprise, cloud and data centre security
- Work on emerging AI threat defence at the forefront of the field
- A clear opportunity to develop towards a Cyber Engineer role
- 2 years of stable, meaningful work within a well-funded transformation program
- A collaborative team environment within a large, respected organisation
