Job summary

Leaf Space S.r.l. is seeking a Software Network Engineer to design, implement, secure and optimize the networking software stack for a resilient, self‑organizing mesh network across a satellite constellation.

You will design routing, SDN-based control frameworks, and secure real‑time communication for space environments. This role blends deep networking with systems engineering, working with RF, DSP, FPGA and security teams to ensure end‑to‑end secure communication from PHY to application

Qualifications

• Proficiency in Python, C/C++, Rust or similar programming languages, with experience developing software for embedded or resource-constrained environments.
• Experience with embedded Linux and firmware development.
• Strong understanding of wireless networking, link-layer behavior, and dynamic topology management.

Responsibilities

• Develop distributed mesh-network algorithms adapting to orbital topology changes.
• Architect and implement SDN-based networking frameworks for dynamic topology management and cross-link orchestration.
• Design and implement SDN-based networking frameworks and programmable control-plane logic for dynamic topology management.
• Integrate cybersecurity across all layers of the communication stack, including encryption and authentication.
• Implement real-time communication stacks optimized for radiation-tolerant processors and constrained onboard computing.
• Collaborate with RF, DSP, FPGA, and security teams to ensure end-to-end secure communication from PHY to application layers.
• Ensure reliability and robustness through redundancy, error handling, watchdogs and secure failover.
• Develop simulation and emulation frameworks for constellation-scale networking behavior and orbital dynamics.
• Participate in design reviews and mission readiness activities across software and RF engineering teams.
• Contribute to system-level architecture, including protocol selection and interface definitions.
