Full Job Description

Company: Singtel Group

Every day, millions of Australians connect, work, stream, and stay in touch on the Optus network. When it works seamlessly, it’s easy to take for granted. But behind it is a team making thousands of decisions every day - decisions that keep people, businesses and communities connected.

Right now, Optus is passionate about getting the fundamentals right – simplifying how we work, lifting standards, and building a more reliable, resilient experience for our customers. It’s not about surface-level change. It’s about how we make decisions, how we work together, and how we deliver.

As a Systems Engineer, you will work closely with technical and business teams to support building, implementing, and operating regulatory systems. These systems must align with telecommunications legislation and national interest requirements.

If you’re looking to do work that matters - and help build what comes next - this is your opportunity to be part of it.

Due to the nature of this role, you must be an Australian Citizen who holds (or be eligible to acquire) an Australian Government security clearance.

What You’ll Do

Assist senior engineers in delivering end-to-end solutions across the technology lifecycle, from development through to operations
Contribute to highly available, secure, and scalable systems, maintaining reliability of critical regulatory platforms
Partner with internal teams and external stakeholders, including government and law enforcement agencies, to support solution delivery and operations
Participate in security risk assessments and help maintain security architecture in regulated environments
Support continuous improvement through modern engineering practices, automation, and evolving technologies

What You Bring

Experience in full stack, end to end, systems support, including infrastructure build and operate
Linux experience (essential)
Virtualization (Proxmox) and Kubernetes (Rancher) experience
Software development using:

Go (essential)
Rust (familiarity, desire to develop the skillset is essential)
Python (desired, not essential)
Gitlab CICD and SDLC

Experience leveraging modern cloud native builds, tooling and patterns in an entirely on-premises environment. E.g. Terraform, Ansible, Packer etc
Datacenter experience including the installation and maintenance of server, network and storage
Strong communication and stakeholder engagement skills
Relevant tertiary qualifications in Computer Science/Engineering; cybersecurity certifications are an advantage

The good stuff….

Competitive remuneration, plus $80 monthly credit, 25% off Optus products and exclusive shopping discounts with our retail partners — making everyday life a little more affordable. Genuine Flexibility - work three days in the office, two days from wherever works best for you.
An office campus that has it all - cafes, chill out zones, GP, post office, gym and on-site childcare centre. It’s built for real life.
Great leave policies, including additional 'Connected’ days to focus on culture, family, health, community, or whatever matters most to you.
Inclusive, carer-neutral paid Parental Leave of up to 16 weeks, because family comes first.
Build meaningful connections through colleague-led networks and diversity initiatives including Culture Connect, Elevate Women, Disability Network and Express Yourself (LGBTQIA+).
Your wellbeing matters, so we offer with free counselling and support services, available 24/7 in-person, by phone, SMS, or video.
A free Optus bus from Macquarie University Metro Station (every 6-8 minutes); morning and afternoon. Or, heaps of onsite parking. Plus, end of trip facilities with lockers, showers, irons and hair dryers.

Not every box ticked? Apply anyway. We believe the right approach matters more than a perfect CV. We’ll back you to grow from there!

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.
