Description
Core Network Designer/Architect - Voice/VoLTE/IMS/HLR/HSS/EPC
My client, a global telecoms operator is currently seeking an experienced Core Network Designer/Architect to join their Core Voice Network Evolution and Architecture team.
The team is responsible for delivering Tier 1 core voice services, platforms and the support of them through excellent operational support systems. They are responsible for all mobile switching platforms that carry voice traffic on the client's Voice services network from CS voice, IMS, UDC, signalling and interconnection to the outside world.
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. You will have experience of working in a Tier 1 mobile network operator or network equipment supplier to Tier 1 mobile operators. You will have worked in the area of customer databases HLR/HSS/AUC/EIR/UDC/MNP applications, and have experience of the provisioning and charging requirements from BSS stack to enable these applications to integrate into the IMS core. It will be a requirement that you have knowledge of cloud based deployments of those applications. In addition it is expected that you have extensive knowledge of cellular networks and networking principles (2G, 3G, 4G, 5G & IMS) including supporting signalling systems C7, SIP, Diameter and MAP and the interfaces to other network domains, EPC, CS, IMS, BSS etc. You will also preferably have knowledge of technology in the standards arena and the understanding of traffic, switching and radio theory/principles.
You will be expected to produce end to end Technical feasibility solutions and high level designs for complex implementations, working with teams across multi-disciplined areas, such as service design, IP design, packet core design, IMS design and IT.
Your extensive knowledge will be used as a source of expertise to identify and solve design issues or impacts around HLR/HSS/AUC/EIR/MNP/UDC, through testing and initial deployment.
You will have experience of network provisioning. Specifically around the implementation of, Voice core element provisioning for HLR/AUC, HSS, UDC ( IMS and IMS services ENUM), EIR and experience of REST interface for provisioning. It would be advantageous to have working knowledge of 5G standalone or standalone and experience of TLS 1.2 connectivity and mutual provisioning (non-authentication).
