Key Tasks and Activities: 

Develops customer network cloud infrastructure architecture for IMS that will be the Voice infrastructure for 4G and 5G services, based primarily on Kubernetes and VMWare cloud platform. Develops high level solution design (decompose the requirements into the functional blocks, defines solution components, external and internal interfaces, responsibilities of the components, network protocols) as input for overall technical solution Creates solution details including components, external and internal interfaces, responsibilities of the components, network protocols to be used, component flow charts that includes multi-vendor environment  Keeps in permanent contact with Customer’s stakeholders by means of regular meetings and workshops    Acts as key bridge between backend support and R&D teams and the project delivery team to identify and manage technical and scope risks Performs technical risk evaluation and plans to mitigate risks of proposed design/solution. Evaluates new technologies and sets a direction for future technical capability demands Plan the migration of traffic from existing legacy network to the IMS on cloud infrastructure

 

Competences:

A deep understanding of how IMS network is designed for Consumer and Enterprise including full understanding of 3gpp specifications and IMS use cases and integration with 5G networks Practical experience designing and deploying IMS network for 4G and 5G networks  Architectural know how on special HW/SW based tech such as SR IOV, PCI pass-through, DPDK and accelerators  End to end architectural know how on following: IMS and VoLTE/ VoNR Architecture IMS / VoLTE/ VoNR use cases and call flows End-2-end design for break-out and break-in calls for IMS VoLTE/ VoNR 5G Services Based Architecture Security aspects including Defence-in-depth  Kubernetes, RHEL host OS & Linux components Integration of IMS to legacy voice networks VoLTE/VoNR roaming and operator interworking  Internetworking between cloud infrastructure and container functions via VXLAN GW Tenant virtual network implementation stretching across multiple NFVI Data centers Security and auxiliary services (VPN, FW, DHCP, DNS etc.) in Kubernets and VMWare clouds

Impact

Impact is short-term through individual and team contributions. Scope is primarily within own subject area in a function/unit. Actions and errors impact on program, project or function. Provides measurable input into new products, processes, standards or operational plans in support of the organisation's business strategies, with some impact on business unit/ function overall results.

Managerial/Supervisory: Clear managerial responsibilities for people. Typically first level of solid line management. Interprets policies. Ensures existing plans are put into operation. Executes and/or oversees processes to meet customer needs. Responsible for analysis, design & development of policies, plans, programs. 

Innovation

Carries out specialised activities/projects according to general direction. Influences others to support decisions. Works mostly independently. Analyze situations or data that requires review of relevant factors. Solutions can often be checked and proved. Demonstrates success in multiple roles and is adaptable to manage complex changing business environments.
