It matters to us that Team O2 is as diverse as the communities we serve. We’re aware that we need more diversity in our senior leadership roles, so we welcome and encourage people from all backgrounds to apply. Whoever you are, O2 has a place for you. 

 

Come join us.

 

About the Team:

 

Transmission Engineering are part of Telefónica UK Networks, and are responsible for the architecture, evolution, design and infrastructure capacity of our mobile core and access transmission IP networks.

 

From our high capacity dark fibre core, to our IP Ethernet backhaul network, we deliver innovative and class leading solutions utilising some of the latest and most exciting transmission and transport technologies.

 

Telefonica UK co-operates with a number of providers of Optical, Microwave, Ethernet and IP connectivity products. Using these products as the underlying technologies, the Transmission Engineering team builds IP connectivity solutions between Core RAN equipment as RNCs, BSCs and Security Gateways to Cell Site Equipment, as BTSs, NodeBs and eNodeBs.

 

About the Role:

 

Working with Architects and designers within the Transmission Engineering team, the role holder will lead the IP design activities within the Mobile Backhaul Transport Network as well of some legacy (TDM and Ethernet) infrastructure. The IPVPN and Mobile Backhaul TDA will have the support of other transmission designers and will be responsible for the delivery of working transport designs including documentation, lab tests and First Office Application (FOA).  The final designs will ensure the correct interconnection of the backhaul network with the Radio Access equipment and the Core Aggregation nodes with special consideration to QoS aspects. Development of Telefonica UK’s TWAMP based performance monitoring platform is also part of the scope of work for this position.

 

Key Responsibilities:

 

  • Telefonica UK co-operates with a number of providers of Optical, Ethernet and IP connectivity products. Using these products as the underlying technologies, the Transmission Engineering team builds IP connectivity solutions between Core RAN equipment as RNCs, BSCs and Security Gateways to Cell Site Equipment, as BTSs, NodeBs and eNodeBs.
  • Role responsibilities therefore include leading the development, documentation and updates of IP networking designs that make use of these connectivity products. The role holder shall consider product specifications as for example physical availability, capacity and delay, commercial evaluation and selection, testing, integration and operation. The IPVPN and Mobile Backhaul TDA will work closely with counterparts in our suppliers’ design teams to ensure cost effective design solutions.

 

  • Solutions must be aligned with business requirements and technology standards that include network simplification, increasing capacity, resilience, disaster recovery, network management and security.
  • The role requires business and commercial skills in addition to high levels of technical expertise. From time to time it will be necessary to produce RFx documentation for transmission network solutions, to evaluate supplier responses in conjunction with Procurement functions and to provide internal financial justification (business case) to progress initiatives.
  • The role holder is expected to keep abreast of applicable technology developments and understand how they may be applicable to Telefónica UK.         

 

What We Need from You:

 

Essential criteria

 

  • Deep theoretical and practical knowledge of TCP, UDP and the main L3/L2 routing protocols.
  • Experienced in designing, planning, configuring and testing of IP/MPLS transport networks.
  • Direct experience in defining IP Quality of Service configurations including HQoS and the mechanisms used to prioritize traffic at Ethernet and IP layers.
  • Deep understanding and practical experience in defining IP addressing policies applicable to carrier class networks.
  • Direct experience in creating High Level and Low Level Designs and Scopes of Work applied to IP Networks.
  • Act as the Technical Lead for the projects assigned and work in co-operation with the Project Manager to identify the involved parties and resources required for each project.
  • Estimate effort requirements, as expressed in man-days count.
  • Applicants will also ideally be degree level qualified, with significant experience with working in a telecommunications technical design or architecture role obtained from working within a network operator or equipment vendor.

 

Desirable criteria

 

  • Familiarity with transport design in mobile networks (Radio Access Network) would be highly advantageous.
  • Familiarity with BT’s MEAS and IPVPN backhaul products.
  • Experience of designing mobile backhaul networks for Ericsson and Nokia Radio Access Networks would be highly advantageous.
  • Experience in producing HLDs and LLDs for Transport IP Network elements preferably related to Nokia (ALU) 7750 environments.
  • Experience in transport designs making use of Juniper platforms and specifically MX and PTX series routers and EX4300 used as Satellites, implementation of advanced QoS and Policy Routing in JunOS, JunOS Space EMS, and Juniper Northstar.
  • Knowledge of implementation of VPLS bridging and eVPN.
  • Good understanding of Virtualization concepts – Experience with the vMX.
  • Experience in SLAX scripting.
  • Experience in designing backhaul solutions for mobile access is desirable.
