The ideal candidate will be network engineer possessing excellent problem-solving skills and demonstrate a proactive approach to issue resolution.

Working knowledge of VoLTE and VoWiFi call flows, IMS registration, SIP/Diameter signalling within the voice path, and common failure modes in mobile voice services.
Familiarity with GTP-C and GTP-U protocols — able to interpret signalling logs and identify session-setup or user-plane failures.
Understanding of mobile roaming operations: inter-PLMN signalling, visited/home network interactions, and the impact of roaming on data and voice services.
Experience working in or supporting an MVNO or thick-MVNO model, understanding the split of responsibilities between host and virtual operator.
Hands-on experience with CLI-based tools and network management platforms.
Solid understanding of IP networking fundamentals (routing, switching, DNS, DHCP) as they apply to mobile backhaul and core transport.
Experience with telecoms change and incident management processes.
Ability to interpret the information provided by network monitoring systems and take appropriate action to resolve incidents.
Strong team ethic working in an unpredictable operational environment.
Demonstrated ability to remain focused and effective during high-impact incidents.
