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.

At Optus, we're focused on building resilient, modern security capabilities that help protect our customers, people, and business. We're looking for a Senior Security Platform Engineer – SIEM & SOAR to help engineer and evolve the enterprise platforms that power our cyber defence operations.

This is a hands-on engineering role for someone who enjoys solving complex technical challenges, automating everything possible, and building scalable security platforms that enable faster and more effective threat detection and response.

What You’ll Do

Design, build, and maintain enterprise SIEM and SOAR platforms that support critical cyber defence operations across the business.
Onboard, normalise, and enrich security telemetry from a broad range of systems, ensuring high-quality data is available for threat detection and investigation.
Develop automation workflows, integrations, and Python-based solutions that improve efficiency, reduce manual effort, and enhance response capabilities.
Manage detection content, platform configurations, and automation deployments using Detection-as-Code, CI/CD, and engineering best practices.
Partner closely with Cyber Defence and engineering teams to continuously improve platform performance, detection coverage, and automation effectiveness.

What makes you perfect

Proven experience engineering and supporting enterprise SIEM and/or SOAR platforms within a security operations, cyber security, or platform engineering environment.
Strong technical skills in log management, telemetry onboarding, security automation, and platform integration.
Hands-on experience with scripting, API integration, and developing automated solutions that streamline security operations.
Knowledge of cloud security logging, Microsoft 365 and Entra ID telemetry, and modern security monitoring practices.
A collaborative, automation-focused approach, with strong problem-solving skills and a passion for continuous improvement and innovation.

What's in it for you?

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, 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.
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.
Free Optus bus from Macquarie University Metro Station (every 6-8 minutes); morning and afternoon.

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. We also want to do our best to make our recruitment process inclusive. If you require any adjustments or accessibility support to participate fairly and equitably in the recruitment process, please email [email protected] or call 1800 309 170. We're here to help.
