As a designer you will report to the core network evolution manager. You will be working alongside other design colleagues to provide network designs and processes to support new business initiatives. You will be responsible to drive the design changes across mobile network customer databases, HLR/HSS/UDC/EIR/AUC and the interfaces to northbound BSS provisioning systems.
As part of a project team you will ensure designs are customer centric, of sound design and deliver to the needs of internal customer requirements. The role includes working with suppliers to specify requirements, review compliance statements, ensure use cases are designed for, and act as the single point of contact for platform and service design related issues for existing and new network elements.
The role will be part of a team delivering network designs for core voice platforms and to support service designs using those platforms, including IMS and Legacy mobile core voice network nodes and UDC platforms.
