Senior Network Engineer

Aim high, go beyond!

At Open Cosmos we are solving the world’s biggest challenges from space, providing businesses, governments and researchers access to more readily available information than ever before - ready for the challenge?

Then read on...

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

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
