About the Role
The Satcom team is responsible for the design, delivery and performance of Open Cosmos’ satellite communications services, spanning the space segment, ground infrastructure and global connectivity.
As we continue building out our next-generation Satcom platform, we’re looking for a Senior Network Engineer to turn network architecture into resilient, high-performance transport capabilities across a dynamic LEO constellation environment.
What will you be doing?
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

No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You’ll bring
- 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
