Date: 14 Aug 2026

Location: Sydney, Australia

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

Company: Singtel Group

Daily, millions of Australians link up, work, stream, and communicate via the Optus network. When it runs flawlessly, it’s easy to underestimate. However, behind it is a team making thousands of decisions every day—choices that maintain connections among people, businesses, and communities.

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.

The Senior Systems Engineer in the Regulatory Projects team will have a high level of technical expertise to support Optus in meeting a range of regulatory obligations. The role also requires strong stakeholder management skills, as you will regularly meet with representatives from government agencies, vendors, and internal teams. You will be responsible for supporting innovative technical solutions to address customer requirements and government initiatives through the solution’s life cycle.

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 | Your day to day will consist of

Developing and supporting solutions for Optus to meet its obligations under the Telecommunications Act to provide industry assistance on national interest matters.

Supporting the build, development, and maintenance of regulatory solutions for any of the Optus products or offerings in the market.

Supporting existing regulatory solutions, systems, and infrastructure.

Acting as a point of contact for support to government agencies using regulatory solutions provided by Optus.

Participating in security risk assessments and maintaining the security architecture for regulatory systems.

What You Bring | What makes you perfect for the role?

Experience in full stack, end to end, systems design and engineering, including infrastructure build and operate.

Strong Linux experience is 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 designs, 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 equipment.

Strong communication and stakeholder engagement skills.

Relevant tertiary qualifications in Computer Science/Engineering; cybersecurity certifications are an advantage.

Data analytics abilities desirable.

The good stuff…. | What’s in it for you?

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 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.
