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
