Full Job Description

Technical Specialist

Date: 1 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.

The role is a senior network security expert responsible for designing, governing, and managing secure network architectures and platforms, while ensuring compliance with security standards and best practices. It involves close collaboration with engineering, cyber security, and operations teams to design and approve secure solutions such as firewalls, segmentation, and encryption technologies. The position also drives security improvements, provides technical leadership and mentorship, and supports risk assessment, incident response, and continuous enhancement of network security.

Your day to day will consist of

Lead PIR and rep CSE across all problem management related engagements
Design, implement, and maintain firewall solutions using Fortinet (FW, Proxy, VPN) and Check Point platforms
Provide Tier‑3 technical support to resolve complex and critical network security incidents
Translate business, security, and network requirements into scalable and secure firewall designs
Deliver firewall migrations, upgrades, policy optimisation, and high‑availability implementations
Apply routing and switching knowledge to interpret network architectures and security traffic flows
Work closely with Network, Cyber Security, and Operations teams to ensure secure end‑to‑end designs
Perform security assessments, troubleshooting, and root‑cause analysis for firewall and VPN services
Contribute basic scripting and automation to improve operational efficiency and repeatability
Ensure designs align with security standards, best practices, and lifecycle (EOL/EOS) requirements

What makes you perfect for the role

Degree in Telecommunications Engineering (or related field) or equivalent experience
At least 8 years’ experience in telecommunications or large enterprise environments, with strong expertise in Fortinet and Checkpoint
Solid understanding of operational processes, fault management, and diagnosing customer issues
Proven ability to manage major faults across multiple platforms and communicate effectively with senior stakeholders (up to GM level)
Experience in testing/PoC environments, including understanding methodologies and platform limitations
Background in large-scale network design and implementation, with scripting skills (e.g., Python, Perl) as an advantage

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.
