Company: Singtel Group

Optus is an Australian telecommunications company, delivering more than 11 million services to our customers every day across mobile, broadband, and digital solutions.

The Security Operations Centre (SOC) Specialist plays a critical role in delivering industry-leading security management, monitoring, and support services for Optus Enterprise and its clients. This position focuses on implementing and operating security monitoring solutions, addressing emerging threats, conducting dark web monitoring, and reviewing technical infrastructure and designs. It is a hands-on technical role involving configuration changes and detailed analysis of security data and products.

Working within the Technical Operations group, the specialist will engage with internal and external stakeholders to provide insights and recommendations on security decisions, support operational environments, and contribute to broader information security initiatives.

** Due to the nature of this role and security clearance requirements, applicants must be Australian citizens.

What you’ll be doing

Investigate complex cases by correlating patterns from SIEM platforms (e.g., Splunk, DEVO) and other security data sources to identify threats and anomalies.
Configure, manage, upgrade, and maintain SIEM platforms; develop and tune use cases, alerts, dashboards, and reports to improve detection capabilities.
Create, document, and refine processes for handling and monitoring security solutions, ensuring operational efficiency and compliance.
Collaborate with technical teams to onboard logs, baseline detection thresholds, and enhance threat detection methods.
Configure, manage, upgrade, and maintain Cloud Web Proxy platforms (e.g., Zscaler).
Participate in security incident response processes, including red team exercises; proactively resolve issues to prevent recurrence.
Develop reporting frameworks, deliver operational security reports, and regularly meet with account and security teams to review risks, incidents, and improvements.
Work with SIEM vendors for support issues and provide observations and recommendations to internal stakeholders to strengthen security posture.

What makes you perfect for the role?

3–5 years’ experience in security operations, strong analytical and problem-solving skills, thorough, with preferred certifications such as CISSP, CISM, or CRISC.
Advanced knowledge and hands-on experience with SIEM technologies (especially Splunk), including logging, monitoring, triage, alert reporting, and use case development.
Solid background in day-to-day security operations, incident classification, investigation, remediation, and familiarity with frameworks like NIST, PSPF, and Australian ISM.
Experience with security tools such as Tenable, Symantec Endpoint Protection, Firepower IPS/IDS, vulnerability management, network security, and endpoint protection systems.
Solid grasp of cloud platforms (AWS, Azure, GCP), awareness of ISO 27001 and SOC2 standards, and experience supporting audits.
Ability to analyse data for insights, develop security documentation, and contribute to delivery and project engagements; scripting knowledge for reporting is desirable.

Optus is a place where we let you do you. We offer a range of benefits including:

Competitive remuneration and employee discounts. Make life easier (and more affordable) with $80 monthly credit and 25% off Optus products and unique shopping discounts with our retail partners.
Flexible working arrangements with opportunities to work three days in the office, two days remote or home.
Vibrant and collaborative office campus that includes cafes, convenience store, chill out zones, GP, post office, gym and on-site childcare centre.
Competitive leave policies, including additional 'Connected’ days to focus on culture, family, health, community, or whatever’s important to you.
We support growing families with inclusive, carer-neutral paid Parental Leave of up to 16 weeks.
Direct your own development and build future-ready skills with Optus U’s industry-focused micro-credentials, developed with La Trobe and Macquarie Universities.
Build meaningful connections through employee-led networks and diversity initiatives including Culture Connect, Elevate Women, Disability Network and Express Yourself (LGBTQIA+).
Put your wellbeing first with free access to counselling and support services, 24/7 — in-person, by phone, SMS, or video.
