Job summary

Blue Origin in Seattle invites a Software Development Engineer III to design and test MAC control-plane software for the TeraWave network, enabling space-based communications with high throughput and low latency.

You will collaborate with PHY, modem, networking, platform, and systems teams to build a scalable wireless stack and validate protocol behavior across mobility and varying link conditions.

Qualifications

• Bachelor's degree in CS/CE/EE or related field.
• 4+ years of software development in wireless networking, embedded systems, or high-performance networking.
• Proficiency in C/C++ with concurrent or timing-sensitive software in Linux/RTOS environments.
• Experience implementing communication protocols, protocol state machines, resource schedulers, QoS systems.
• Experience developing and debugging software that interfaces with hardware, embedded platforms, networking systems, or communication devices.

Responsibilities

• Design, implement, and test MAC control-plane software for point-to-point and point-to-multipoint satellite links.
• Develop components of TDMA, DAMA, admission-control, scheduling, and radio-resource-management systems.
• Implement protocol state machines for link establishment, maintenance, reconfiguration, teardown, fault recovery, and beam/satellite/gateway transitions.
• Develop MAC control logic for QoS enforcement, traffic prioritization, flow control, retransmission, and coordinated link adaptation.
• Integrate MAC control-plane software with PHY implementations, modem hardware, networking data planes, telemetry systems, and hardware-accelerated MAC functions.
• Build simulation, test, and performance-analysis tools to validate protocol behavior under mobility, fading, congestion, timing variation, and failure scenarios.
• Diagnose software, protocol, timing, and system-integration issues using logs, telemetry, packet captures, simulations, and hardware test environments.
• Deliver MAC control-plane features through design, implementation, code review, hardware integration, system qualification, and operational deployment.
