#job-location.job-location-inline { display: inline; }

Company: Singtel Group

Optus is a leading telecommunications and technology company, delivering innovative solutions that keep millions of Australians connected. As we continue to evolve into a digital-first, AI-enabled organisation, our Cyber Defence Operations team plays a critical role in protecting our customers, networks and data.

We’re looking for a Threat Detection Engineer to join our Cyber Defence Operations – Defence Operations team, where you will design, build and continuously improve detection capabilities to defend against evolving cyber threats.

Due to the nature of this role and the environments supported, Australian Citizenship, and the ability and willingness to obtain and maintain a Government Security Clearance is required.

What You’ll Do

Partnering closely with Cyber Security leaders, SOC analysts, threat intelligence, and engineering teams, you will:

Design, develop and optimise detection logic across SIEM and EDR platforms (e.g. Microsoft Sentinel, Defender XDR, Cortex XSIAM)
Own the end-to-end detection lifecycle including requirements gathering, rule authoring, testing, deployment, tuning, and retirement
Improve detection precision through noise reduction, alert tuning, suppression logic and false positive management
Configure analyst-facing environments including incident views, triage workflows, alert grouping and scoring models
Conduct detection coverage analysis aligned to MITRE ATT&CK and threat intelligence insights
Collaborate with SOC, threat hunting and red/purple teams to continuously uplift detection capability and operational effectiveness
Contribute to detection-as-code practices, including version control, documentation, and CI/CD pipelines
Participate in security operations rotations, supporting incident triage and response activities

What You’ll Bring
Hands-on experience in cyber security operations (SOC, incident response or threat detection engineering) – this is essential
Strong understanding of security concepts including attack lifecycle, threat actor techniques, and alert triage workflows
Familiarity with SIEM and EDR platforms, and ability to analyse logs across endpoint, identity and network sources
Experience or exposure to detection engineering, rule creation, or threat-informed defence practices
Strong problem-solving skills with the ability to balance detection coverage and operational noise
Effective communication skills and ability to document clearly in operational environments
A growth mindset, with eagerness to learn and develop within a high-performing cyber team

The Good Stuff…
Competitive remuneration and exclusive employee discounts
Flexible working with a hybrid model (office and home)
Access to on-site facilities including cafes, gym, childcare and more
Inclusive parental leave and flexible policies supporting families
Ongoing development through Optus U and industry-recognised learning programs
Employee-led networks supporting diversity, inclusion and belonging
24/7 wellbeing and support services

At Optus, we are strengthened by others and that means valuing diversity and saying ‘yes’ to embracing individual differences. We are committed to ensuring that our application process provides an equal employment opportunity to all job seekers, including individuals from diverse gender, cultural and linguistic backgrounds, individuals with a disability, individuals identifying as being part of the LGBTQIA+ community, individuals who may have served in the armed forces or who identify as Aboriginal and/or Torres Strait Islander.
