Sr Software Engineer - Network & SDN - TeraWave

Application close date:

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight! 

As a Senior Network Engineer for Network Architecture & SDN at TeraWave, you will contribute significant technical expertise to the design and implementation of the "brain" of our constellation, developing a dynamic, self-healing network that operates at orbital speeds across our multi-orbit constellation of 5,408 optically interconnected satellites. You will work on solutions for a topology that changes every second, help design inter-satellite links (ISLs) that move at 27,000 km/h, and implement seamless handoffs for users on the ground—all while adhering to strict power and latency budgets.

In this role, you will apply your strong expertise in networking architecture and software-defined networking to develop critical components of our space-based communications system. You will collaborate with principal engineers and technical leaders to implement innovative approaches to routing, traffic management, and network resilience. This position offers an excellent opportunity to work at the intersection of advanced communications technology and orbital mechanics, making significant technical contributions to a revolutionary system.

• Implement designs for key components of our hybrid space-ground transport network
• Develop routing solutions, topology management systems, and fast-reroute mechanisms tailored for time-varying LEO constellations
• Create capacity models that translate raw RF link characteristics into effective network-layer implementations
• Implement Software-Defined Networking (SDN) frameworks to support centralized and distributed control planes
• Develop real-time Traffic Engineering (TE) and policy enforcement mechanisms to optimize data flow across constrained satellite payloads and terrestrial backbones
• Implement programmable transport solutions that allow for deployment of new protocols and features
• Develop components for the observability stack using in-band and out-of-band telemetry for packet-level visibility
• Implement "Self-Healing" network logic where real-time telemetry feeds into SDN controllers for automated congestion management and fault isolation
• Develop methods to correlate flow-level tracing with link performance to improve efficiency across the constellation
• Implement packet forwarding solutions that can operate reliably in space environments, optimizing for latency and throughput under power constraints
• Support cross-layer optimization efforts, working alongside RF and Silicon teams to ensure mobility across beams and satellites
• Provide technical guidance within your team and mentor junior engineers on networking best practices

• Bachelor's degree in Computer Science, Electrical Engineering, or related field with 8+ years of experience in network engineering, distributed systems, or telecommunications
• Strong knowledge of BGP, IS-IS, OSPF, and Segment Routing (SRv6/SR-MPLS) in network environments
• Experience implementing or working with SDN controllers and programmable data planes (P4, OpenFlow, or proprietary frameworks)
• Solid understanding of packet processing, ASIC/FPGA forwarding logic, and high-speed switching
• Experience implementing network solutions for wireless, cloud, or service provider networks
• Strong analytical and problem-solving skills
• Good technical written and verbal communication skills
• Experience with development in mission-critical environments

• MS in Computer Science, Electrical Engineering, or related field
• Experience with satellite communications networks or terrestrial/satellite hybrid networks
• Knowledge of telemetry pipelines and analytics for network monitoring
• Background in graph theory or network optimization
• Contributions to networking projects, internally or open-source
• Familiarity with satellite communications systems
• Understanding of regulatory considerations for communications systems
• Experience with modeling and simulation tools for network performance analysis
