Job summary

Blue Origin, Seattle, WA, is seeking a Senior Software Engineer to design and implement MAC control-plane software for the TeraWave network, enabling high-throughput, low-latency space-based communications. You will work with PHY, modem, networking, platform, and systems teams to deliver scalable, reliable MAC protocols.

The role emphasizes architecture leadership, TDMA/DAMA-based resource management, and end-to-end integration from prototyping to deployment.

Qualifications

• Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or related technical field.
• Seven or more years of software-development experience in wireless networking, communication systems, embedded systems, or high-performance networking.
• Advanced proficiency in C or C++ with concurrent, timing-sensitive software in Linux, real-time Linux, or RTOS environments.
• Experience designing or implementing wireless MAC protocols, resource schedulers, protocol state machines, flow-control mechanisms, or QoS systems.
• Experience developing software through hardware integration, system testing, performance characterization, and production deployment.

Responsibilities

• Design and implement MAC control-plane software for satellite links (point-to-point and point-to-m multipoint).
• Develop scalable TDMA, DAMA, admission-control, and resource-allocation algorithms for many beams and terminals.
• Implement state machines for link establishment, maintenance, reconfiguration, teardown, fault recovery, and transitions between beams, satellites, and gateways.
• Develop MAC control logic for QoS enforcement, traffic prioritization, flow control, retransmission, and coordinated link adaptation with PHY/modem teams.
• Define interfaces between the MAC control plane, PHY layer, modem hardware, networking data plane, and hardware-accelerated MAC functions.
• Evaluate centralized, distributed, and hierarchical MAC-control architectures considering latency, stale state, failures, and constellation-scale operation.
• Build simulation, test, telemetry, and performance-analysis capabilities to validate protocol behavior under mobility, fading, congestion, and failure scenarios.
• Lead MAC control-plane development from architecture and prototyping through hardware integration, system qualification, and deployment.
