Our GSaaS solutions have been recognized by the market for their efficiency, security, and effectiveness in supporting different applications, from remote sensing to IoT communications.
JOB OVERVIEW
The Software Network Engineer will design, implement, secure, and optimize the networking software stack that enables a resilient, self‑organizing mesh network across a constellation of satellites. You will design and implement routing, SDN‑based control frameworks, link‑management systems, cybersecurity protections, and distributed‑systems capabilities that allow spacecraft to communicate reliably under constantly changing orbital conditions.
This role blends deep networking expertise with systems engineering, real‑time constraints,



SDN control‑plane design, and the unique challenges of securing communication in space environments.
RESPONSIBILITIES
Design and implement networking protocols for inter‑satellite and satellite‑to‑ground communication, including routing, link‑state management, congestion control, and fault‑tolerant data transport.
Develop distributed mesh‑network algorithms that adapt to dynamic topology changes driven by orbital motion, intermittent connectivity, and variable link quality.
Architect and implement SDN‑based networking frameworks, including programmable control‑plane logic for dynamic topology management, policy enforcement, and cross‑link orchestration.
