We have a great new role for a Transmission & IP Designer to join our Core Engineering team!

This is a key role working with Architects and other Designers to develop designs and low-level configurations for Virgin Media O2’s access, aggregation and core transport networks.

Virgin Media O2 co-operates with various providers of optical, microwave, Ethernet and IP connectivity products and, using these products, builds IP connectivity solutions between the radio equipment (that’s located at cell sites and, in some cases, at core sites), access devices (such as OLTs, CPEs, etc.) and the core transport networks.

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.

Role Responsibilities

• Development, documentation and updates of Layer 2 and IP network designs that make use of Layer 2 and Layer 3 transport products.
• Production of routing designs for the mobile MPLS core to meet agreed service targets and resilience levels.
• Ensure that all solutions are aligned with the business requirements and technology standards that include network simplification, increasing capacity, resilience, disaster recovery, network management and security.
