• Five or more years of experience in software development for networks, distributed systems, or telecommunications.
• Experience implementing SDN controllers and programmable data planes such as P4, OpenFlow, or proprietary frameworks.
• Experience developing software for mission-critical systems in production environments.
• Experience with satellite or hybrid terrestrial-satellite networks.
• Knowledge of BGP, IS-IS, OSPF, and SRv6/SRv-MPLS.
• Background in graph theory or network optimization.
• Applicants must be a U.S. citizen or national, U.S. permanent resident, or lawfully admitted into the U.S. as a refugee or granted asylum.
• Contributions to networking projects, internally or open-source, and understanding of regulatory considerations for communications systems.
• Strong analytical, problem-solving, and technical written and verbal communication skills.

Responsibilities

• Develop routing solutions, topology management, and fast-reroute mechanisms for time-varying LEO satellite constellations.
• Implement software-defined networking frameworks supporting centralized and distributed control planes across the constellation.
• Implement self-healing network logic using real-time telemetry for automated congestion management and fault isolation.
• Develop observability components using in-band and out-of-band telemetry for packet-level visibility and flow-level tracing.
• Implement packet forwarding solutions optimized for latency and throughput under power constraints.
• Support cross-layer optimization with RF and Silicon teams to ensure mobility across beams and satellites.
• Collaborate with principal engineers, senior software developers, and technical leaders on routing, traffic management, and network resilience.
