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.

We are seeking a Senior Security Platform Engineer – DevSecOps to lead application security engineering and DevSecOps uplift across Optus. You’ll work closely with development, platform, architecture and security teams to embed secure-by-default practices across the software development lifecycle, automate security controls and improve the way teams deliver secure software.

If you thrive in a hands-on senior role where you can shape AppSec strategy, provide technical leadership, mentor engineers and turn security requirements into practical, reusable controls, this role is for you.

WHAT YOU’LL DO

Lead and enhance DevSecOps and secure software development lifecycle practices.
Embed security testing into development workflows.
Automate security, compliance, and software supply chain controls using policy-as-code.
Provide security expertise through code reviews, architecture reviews, and developer support.
Build and maintain secure CI/CD pipelines with automated controls, quality gates, and assurance.
Drive security automation, platform management, governance, and continuous improvement across cloud and application environments.

WHAT MAKES YOU PERFECT FOR THE ROLE?

Relevant qualification in IT, Computer Science, Software Engineering, or equivalent industry experience.
5+ years' experience in DevOps, platform engineering, infrastructure automation, and CI/CD pipeline development.
Strong scripting and automation expertise using Python, Bash, PowerShell, APIs, and GitOps practices.
Hands-on experience with application security, vulnerability management, and shift-left security.
Proficiency in CI/CD governance, Infrastructure-as-Code (IaC), Policy-as-Code, repository management, and security compliance automation.
Strong leadership, communication, collaboration, and problem-solving skills with a focus on automation, continuous improvement, and developer enablement.

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.
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.

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. When you contact us, please advise your preferred method of contact and we will be in touch within 48 hours.
