The role involves managing performance KPIs, troubleshooting, and optimizing RAN and Core networks, requiring extensive experience and technical knowledge in mobile technologies and protocols.
Join our Team
About this opportunity:
We are seeking a highly motivated and skilled RAN & Core Performance Engineer to join our telecom network team. The candidate will be responsible for Performance KPI's, assurance, troubleshooting, and optimization of both Radio Access Networks and Core Network (CS/PS/VAS) components. This role requires in-depth technical knowledge of mobile technologies (2G/3G/4G/5G/ NBIoT), Core, network architecture, and protocols, etc.
What you will do:• Network performance management of 2G/3G/4G/5G/ NBIoT RAN.• Perform KPI monitoring, root cause analysis, and performance tuning of radio networks.• Collaborate with RF engineers for coverage and capacity planning.• Troubleshoot site-level and cluster-level RAN issues (call drops, interference, handover failures).• Support in Pre-post analysis for any new site integration, software upgrades, and feature implementation.• Network performance management of Core domain (CS/PS/VAS), EPC/5GC components: MME, SGW, PGW, AMF, SMF, etc.• KPI analysis and troubleshooting.• Troubleshoot signalling and bearer path issues using protocols like GTP, Diameter, SCTP, SIP.• Analyze call flows, CDRs, and trace logs for issue resolution.• Support in Pre-post analysis for any new site integration, software upgrades, and feature implementation.• Work with vendors for core software upgrades and capacity expansion.
The skills you bring:• Bachelor's degree in Electronics/Telecommunications/Computer Science or related field.• Strong understanding of RAN and Core (EPC, 5GC, NG-RAN, etc.).• Need 9 to 12 years of experience.• Experience with tools like Wireshark, TEMS, NetAct, ENM, OSS platforms, Kalix, Netcool, NGPM, Service now, SIGOS, EEA.• Knowledge of telecom protocols: LTE/NR, GTP, S1AP, X2AP, Diameter, NAS, NGAP.• Familiarity with network virtualization (NFV), SDN, and cloud-native core (preferred).• Good analytical, problem-solving, and communication skills.• Should be able to work in night Shift, On-call support rotation (as per project requirements)

What you need to know about the Melbourne Tech Scene
Home to 650 biotech companies, 10 major research institutes and nine universities, Melbourne is among one of the top cities for biotech. In fact, some of the greatest medical advancements were conceptualized and developed here, including Symex Lab's "lab-on-a-chip" solution that monitors hormones to predict ovulation for conception, and Denteric's vaccine for periodontal gum disease. Yet, the thousands of people working in the city's healthtech sector are just getting started, to say nothing of the tech advancements across all other sectors.
