Full Job Description

Network Engineer

Date: 1 Jun 2026

Location: Sydney, Australia

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're looking for a skilled and adaptable Network Engineer (Technical Facilities and Non-Exchange) ISP to join our Network Operations team based in Sydney. In this hands-on field role, you'll be at the frontline of keeping Australia's network running — delivering, maintaining and restoring critical infrastructure across Exchanges, CEVs, FANs, Hubs and mobile sites. You'll be part of a collaborative, high-performing team where your technical expertise services millions of customers every day.

What You'll Do

Perform Service Delivery (build and commissioning) and Service Assurance/Restoration activities across Switching, Transmission and Enhanced Service platforms for both mobile and fixed services.
Provide rapid response to critical incidents, including 24/7 shift work and on-call arrangements to maintain network integrity and meet SLA targets.
Carry out routine, preventative and corrective maintenance across major technical facilities including Exchanges, CEVs, FANs and Hubs.
Deliver Level 1 technical power and cooling support — monitoring and maintaining BMS, UPS, DC plant, HVAC, emergency generators and fire systems.
Monitor, audit and ensure compliance of Exchange and Datacentre operations, supervising vendors and contractors to uphold Optus standards.
Mentor and coach new field engineers and cadets, contributing to continuous improvement of standard procedures and team capability.

What makes you perfect for the role?

Current Drivers license and car
A technical qualification (Cert III, Cert IV, diploma or degree) in Telecommunications Engineering or a related discipline, or equivalent industry experience.
Experience in fixed transmission networks with strong knowledge of network design and technologies.
Broad knowledge of critical infrastructure including DC systems, rectifiers, batteries, UPS, PDUs, HVAC, fire panels and emergency generators.
Sound understanding of transmission and digital systems, switching, HFC, and mobile technologies including 5G/edge.
Experience managing or working within Exchanges and Datacentres, with the ability to troubleshoot complex, non-standard problems under pressure.
A collaborative team player with the ability to work across departments, contribute to MOPs, rack layout diagrams and floor plans, and adapt in a fast-paced, ever-changing environment.

The good stuff….

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.
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.

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.
