Network Engineer – IMS & Core Network Migration
Location: Sydney
Type: 6-month contract + extensions
Role Overview
As a Network Engineer for our Telco client, you will be responsible for designing, implementing, and optimising IMS-based voice and multimedia services, leading complex core network migrations, and supporting cloud-native deployments. You'll work in a dynamic, multi-vendor environment and collaborate with cross-functional teams to ensure seamless service delivery.

Key Responsibilities

  • Engineer and maintain IMS core network components, with a focus on Ericsson architecture (CSCF, HSS, TAS, MRF, SBC).
  • Rapidly adapt to Nokia IMS platforms (Cloud Native Communication Suite, TAS, CFX, SBC, MRF).
  • Lead planning and execution of large-scale live core network migrations, including vendor swaps, rollback strategies, and cutover procedures.
  • Support and troubleshoot 4G/5G voice services including VoLTE, VoNR, VoWiFi, and RCS.
  • Design and secure IP networks using BGP, OSPF, QoS, VPNs, and SBCs (Ribbon, Metaswitch).
  • Deploy and manage VNFs/CNFs on cloud platforms (OpenStack, Kubernetes, VMware).
  • Use orchestration tools to automate and scale IMS deployments.
  • Perform diagnostics and root cause analysis in multi-vendor environments.
  • Communicate effectively with technical and non-technical stakeholders.

Required Skills & Experience

  • Minimum 5 years in IMS core network engineering within a Telco or equipment vendor.
  • Strong understanding of 3GPP IMS standards (SIP, Diameter, RTP, SDP, ISUP, H.248, Megaco).
  • Proven experience with Ericsson IMS products and architecture.
  • Nokia IMS experience highly desirable; candidates without it must demonstrate rapid learning ability.
  • Hands-on experience with VoLTE, VoNR/5G Voice, VoWiFi, and IMS-based multimedia applications.
  • Solid IP networking knowledge and experience with interconnect SBCs.
  • Familiarity with cloud-native technologies and orchestration tools.
  • Excellent troubleshooting, communication, and documentation skills.
  • Ability to work independently and thrive in high-pressure environments.
