Network Core Solution Architect - Mission Critical Communications Hub

Your role
In this role you will design, integrate and evolve highly available 4G/5G Mobile Core and mission-critical network solutions, spanning EPC/5GC, IMS, subscriber management, roaming/signalling, service enablement and Telco Cloud infrastructure.
You will own and deliver end-to-end Mission Critical Network Core solutions, covering architecture, engineering, integration, automation and implementation across mobile core and cloud-native/telco-cloud environments. 

• In this role you will play a key role in:
• Design and evolve resilient, highly available Mission Critical Network Core solutions, translating business and service requirements into scalable technical architectures.
• Architect and engineer 4G EPC and 5G Core (5GC) solutions covering key network functions such as MME, SGW/PGW, AMF, SMF, UPF, UDM, AUSF, PCF, NRF, NSSF and related Core NFs, including control-plane and user-plane architecture
• Design and integrate (based on alignment with customer) 3GPP interfaces and protocols, including N1/N2/N3/N4/N6/N9, SBI, NGAP, GTP-U, PFCP and Diameter, supporting registration, session management, mobility and user-plane connectivity. 5GC uses N2 between RAN and AMF, N3 between RAN and UPF, N4 between SMF and UPF, and N6 toward data networks.
