Full Job Description

Senior Technical Specialist

Date: 12 Jun 2026

Location: Macquarie Park, 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.

IP Platform Engineering is responsible for end-to-end management of IP core platforms, including lifecycle planning, cybersecurity compliance, performance monitoring, and addressing business demand across all service streams (Fixed, Mobile, and Enterprise). The role requires acting as a domain lead, independently managing platform engineering, delivering business outcomes, and ensuring successful production deployment through strong technical expertise in telco networks. As a senior position, it also involves leadership, stakeholder collaboration, and vendor management, with an expectation to operate with minimal supervision and develop subject matter expertise.

Your day to day will consist of

Plan and design end-to-end IP core network builds, expansions, and upgrades, including cost–benefit analysis to determine optimal solutions.
Develop and execute implementation plans, issue engineering orders, and proactively manage capacity, upgrades, and consolidation of legacy platforms.
Lead project meetings, guide stakeholders on objectives and direction, and support sourcing and related initiatives.
Maintain strong stakeholder relationships to resolve issues early, demonstrate customer experience improvements, and deliver regular project reporting while mitigating network risks.
Prepare AOP investment plans, contribute to technology reviews, and provide strategic recommendations for IP network solutions and direction.
Support team and organisational capability by mentoring engineers, creating training materials, and effectively communicating complex technical solutions to both technical and non-technical audiences.

What makes you perfect for the role

Extensive industry experience, including 15+ years in telecommunications and 10+ years in IP networking roles.
Strong knowledge of IP networking technologies such as TCP/IP, routing & switching, MPLS, traffic engineering, EoMPLS, and modern data centre technologies (e.g., VXLAN, Cisco ACI, VPC).
Proven experience in network planning, router configuration, and working within telecommunications provider environments, with understanding of platforms, service design, and operations.
Solid project, budget, and platform management skills, along with good documentation capability and ability to engage with middle and senior management.
Effective communication, stakeholder engagement, and presentation skills, with the ability to explain complex technical concepts to both technical and non-technical audiences.

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.
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. We're here to help.
