Requirements

What we're looking for

  • Strong understanding of advanced routing protocols including Segment Routing (SR-MPLS and/or SRv6) and IS-IS

  • Capability to implement and customise routing behaviour within highly dynamic and distributed networks

  • Knowledge of modern Network Operating Systems such as SONiC and routing platforms such as FRRouting

  • Understanding of control plane and data plane architectures, including hardware forwarding integration

  • Knowledge of high-performance networking concepts including throughput, latency, PPS performance, and hardware acceleration

  • Familiarity with specialised networking hardware including SoC-FPGA-based platforms

  • Proficiency in building and operating large-scale network simulation and emulation environments

  • Understanding of network resilience, convergence behaviour, and stability under rapidly changing topologies

  • Knowledge of mobility management and seamless handover strategies within distributed communication systems

  • Awareness of how orbital dynamics influence network topology, routing behaviour, and latency across LEO systems

The role

What you'll do

You will be:

  • Implementing and customising advanced routing protocols including Segment Routing (SR-MPLS/SRv6) and IS-IS for highly dynamic LEO network topologies

  • Developing and integrating custom on-board router platforms using specialised hardware and modern network operating systems

  • Working across control plane and forwarding plane integration to support high-throughput packet processing

  • Designing and executing large-scale network simulations and Digital Twin environments to validate network behaviour under orbital dynamics

  • Validating high-speed forwarding performance, protocol convergence, resilience, and network stability under failure conditions

  • Supporting seamless mobility and user terminal handover mechanisms to maintain low-latency service continuity

  • Building and optimising network transport capabilities for high-throughput, distributed satellite communication systems

  • Collaborating with architecture and platform engineering teams to align implementation with system design objectives

  • Identifying technical constraints, integration risks, and performance limitations to support roadmap and architectural evolution

  • Supporting iterative prototyping, testing, and validation activities across both software and hardware networking environments
