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 hands-on Network Engineer to join our Field Operations team based in Blacktown and surrounds, where you'll play a critical role in keeping Australia's network infrastructure running. From service delivery and fault restoration to routine maintenance and facility management, you'll be the last line of defence for our customers — and a key contributor to a team that takes pride in getting things done right.

What You'll Do

• Perform service delivery, assurance, and preventative and corrective maintenance across switching, transmission, and enhanced service platforms at exchange, CEV, FAN, hub, mobile, and customer sites.
• Provide first-in technical facility support for critical infrastructure including UPS, DC power plant, HVAC, emergency generators, fire systems, and building management systems.
• Respond rapidly to critical network incidents, working to restore services within SLA across consumer and enterprise customers.
• Monitor and manage exchange and data centre environments, overseeing vendor and contractor activity to ensure compliance with Optus standards, safety requirements, and site cleanliness.
• Contribute to continuous improvement by refining operation manuals, work instructions, and methods of procedure, and supporting the development of new field engineers and cadets.
• Provide ad hoc remote support to contractors and vendors, and assist with deploying and recovering portable generators and SatCat equipment during disaster response.

What makes you perfect for the role?

• Comfortable working in a 24/7 operational environment, including shift work, on-call, and recall arrangements.
• A technical qualification (Cert III, Cert IV, diploma, or degree) in Telecommunications Engineering or a related discipline, or equivalent hands‑on experience — ideally with years in fixed transmission networks.
• Solid understanding of transmission and digital systems, switching, HFC, mobile (including 5G/edge technology), and consumer products.
• Demonstrated experience with critical infrastructure such as DC systems, rectifiers, UPS, PDUs, HVAC, chillers, fire panels, and grounding systems, with the ability to provide Tier 2 troubleshooting support.
• Practical experience working in exchanges or data centres, including managing HVAC and power systems.
• Ability to collaborate across teams on projects, MOPs, rack layout diagrams, and floor plans, with working knowledge of tools such as Office 365, ServiceNow, and Tableau.

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.
• 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.
