Working for Open Cosmos

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…

Working in the Connectivity Team

Our connectivity team is responsible for designing and delivering the communication backbone that links Open Cosmos’ satellite systems to users on the ground. From inter-satellite links to gateways, terminals, and cloud infrastructure, we ensure secure, reliable, and scalable connectivity across all layers of the Satcom system.

We work closely with platform, payload, software, and ground segment teams to define system-wide network architectures that support next-generation services like IoT, private networks, 5G/6G NTN, and secure tactical communications.

What will you be doing?

As Network Architect, you will lead the design and evolution of the end-to-end network architecture for Open Cosmos’ Satcom services. You will shape the connectivity layer that integrates satellite platforms, RF and optical inter-satellite links, gateway infrastructure, and terrestrial backhaul.

You will be responsible for defining and optimising network topologies, protocols, and routing strategies to meet service-level requirements for coverage, latency, resilience, and throughput. You will also help develop digital twin models and network planning tools to support mission simulations, service rollouts, and autonomous operations.

You will act as a key interface between technical and business stakeholders, ensuring the network design aligns with customer demands, regulatory constraints, and evolving market trends. Your work will lay the foundation for how our constellations communicate and scale as our services grow.

What you need to be successful

We care about what you can do and how you think. If this role excites you, we want to hear from you, even if you are not sure you tick every box.

Different seniority levels will be assessed for this role.

To succeed in this role, you will need:

• A strong background in designing complex communication networks, preferably within the satellite or telecom industries.
• Deep understanding of IP-based networking (IPv4/IPv6, BGP, MPLS), network design principles, and protocol stacks.
• Proficiency in integrating inter-satellite links (RF/optical) and satellite gateway infrastructure.
• Familiarity with 5G/6G network architectures, non-terrestrial networks (NTN), and relevant 3GPP standards.
• Expertise in network performance modeling, digital twin simulation, and planning tools.
• Solid grasp of SDN/NFV concepts, virtualised networking, and orchestration frameworks.
• Knowledge of secure network design, cybersecurity practices, and compliance for critical infrastructure.
• Strong systems thinking, effective communication, and collaborative leadership abilities.
