What You’ll Do

• Lead resolution of complex or high-severity network faults, particularly when not resolvable by the Managed Service Supplier.
• Provide technical oversight and direction during major incidents to ensure timely restoration of service.
• Manage escalations from Service Assurance Managers, ensuring clear communication and prioritisation of critical incidents.
• Conduct end-to-end Problem Management including root cause analysis, corrective actions, and closure with suppliers and vendors.
• Protect revenue and customer experience through proactive fault reduction across the Transport network.
• Provide input into network expansion and upgrade planning, including assessment and approval of new technologies.
• Drive changes to network design and implementation to improve quality, performance, and reliability.
• Validate and govern planned works (hardware/software changes) to align with quality and performance standards.
• Collaborate with Engineering teams, Managed Services, and Vendors to deliver network strategy and operational improvements.
• Review and sign off on new technology architecture/design to ensure operational supportability.
• Analyse and report on service levels and KPIs, identifying performance issues and improvement actions.
• Deliver training on new tools, technologies, and operational practices to internal staff and managed service partners.
• Authorise and manage security access for vendors and managed service partners.
• Represent Optus as a technical authority in Change Advisory Boards, approving significant network changes.
• Identify and support automation opportunities to enhance customer experience and operational efficiency.
• Audit and fine-tune network alarms to improve monitoring effectiveness and support automation.
• Provide input into tool and platform strategy to ensure alignment with operational outcomes.
• Act as the primary technical escalation point and decision-maker during shifts when operational leaders are unavailable.

What You Bring

• A Bachelor’s Degree (or higher) in Engineering, Telecommunications, or a related field.
• 10+ years’ hands-on experience in maintaining and troubleshooting multi-vendor IP and/or Carrier Ethernet networks (Nokia, Cisco, Huawei).
• Solid understanding of IP and/or Carrier Ethernet network protocols and technologies including BGP, OSPF, IS-IS, MPLS, LDP, Segment Routing, and related control/data plane mechanisms.
• Solid understanding of Layer 2 services (VPLS, Epipe, etc.) and Layer 3 services (L3VPN, EVPN), along with Quality of Service (QoS) mechanisms.
• Experience with network automation tools such as Python and Ansible is highly desirable.
• Vendor certifications (e.g., CCNP, NRS II) are desirable.
• Strong understanding of service operations, including performance and fault management.
• Demonstrated ability to lead and resolve high-severity incidents and cross-domain technical issues.
• Experience managing vendors, delivering projects, and influencing across internal and external stakeholders.
• Strong verbal and written communication skills, including the ability to translate technical detail for business leaders.
• Ability to work independently, take ownership of issues, and implement practical, timely solutions.
• Proven leadership in mentoring, guiding peers, and fostering collaborative team environments.
• Familiarity with automation in Service Assurance processes is highly regarded.
