Apply
We are seeking an experienced Network Design Engineer with deep expertise in service provider-grade MPLS networks and high-availability infrastructure. This role will focus on designing, documenting, and guiding the uplift of an existing transport network to a modernised, scalable, and resilient next-generation architecture.
The ideal candidate brings strong design capability, excellent documentation skills, and the ability to work across engineering, architecture, and operations teams to ensure the delivery of a robust, future-ready network.

Key Responsibilities
  • Lead the overall design of the network, from early planning right through to detailed technical documents.
  • Create easy-to-understand design documents — including high-level designs, detailed designs, diagrams, and migration plans.
  • Design and improve MPLS-based networks to ensure they are reliable, fast, and built for growth.
  • Plan the upgrade of the current network to a newer, more modern platform.
  • Make sure the network is designed with strong resilience and redundancy, so that critical services stay online.
  • Support engineering teams during build, testing, and cutover to ensure the design is followed correctly.

Skills & Experience
  • Proven experience designing large-scale service provider MPLS networks, including L2/L3 VPNs, traffic engineering, and QoS.
  • Strong hands-on expertise with Nokia (Alcatel-Lucent) routing platforms
  • Demonstrated ability to design for high availability, including redundancy, fast reroute, disaster recovery principles, and network hardening.
  • Experience with network migration planning and execution in complex production environments.
  • Understanding of IP, MPLS, BGP, OSPF, IS-IS, Ethernet services, and transport technologies.
  • Familiarity with critical infrastructure environments and associated compliance and security considerations.
  • Strong communication and stakeholder engagement skills.
