This role will encompass support to both test and trial activities to ensure that the designs and low-level configurations are suitable for wider deployment. The role will further extend to the consideration of steps that will facilitate smooth migration from one design / configuration to another.

* Significant experience of L3/L2 routing protocols including BGP and designing of IP, MPLS networks
* Experience of Segment Routing, BGP-LU designs and EVPN Services
* Excellent understanding of Broadband Network Gateway designs and their use in xPON networks
* Direct experience in producing High Level and Low Level Designs and Scopes of Work applied to carrier-grade IP Networks
* Hands‑on experience with at least 2 of the 3 vendors and technologies; Nokia, Cisco and Juniper Core networking technologies including Nokia 7750 SR, Cisco CRS/ASR/7600 and Juniper MX/PTX family platforms
* Solid experience working as Technical Lead for transport projects in co-operation with Project Managers; ability to identify involved parties and resources required for each project
Other Stuff We’re Looking For

* Nokia SRC Certification (NRS, SRA)
* Familiarity with transport design in mobile networks (Radio Access Network) would be highly advantageous
* Experience on sync techniques for mobile infrastructure, specifically PTP and Phase Sync
