Blue Origin; Seattle (WA); On-site; USD 207,000 - 290,000; Full time

Job summary

Blue Origin is seeking a Software Development Engineer III to design, implement, and test MAC control-plane software for the TeraWave satellite network. You will work on a high-throughput, low-latency wireless stack and collaborate with PHY, modem, and systems teams to ensure robust space-based communications.

Responsibilities include developing TDMA and admission-control components, enforcing QoS, and integrating with hardware.

Qualifications

• Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or related technical field.
• 4+ years of software-development experience in wireless networking, communication systems, embedded systems, or high-performance networking.
• Proficiency in C or C++ with concurrent or timing-sensitive software in Linux, real-time Linux, or RTOS environments.
• Experience implementing communication protocols, protocol state machines, resource schedulers, flow-control mechanisms, or 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 satellite links.
• Develop components of TDMA, DAMA, admission-control, scheduling, and radio-resource-management.
• Implement protocol state machines for link establishment and transitions across beams, satellites, and gateways.
• Develop MAC control logic for QoS, traffic prioritization, flow control, and link adaptation.
• Integrate MAC control-plane software with PHY, modem, networking data planes, telemetry, and hardware accelerators.
• Build simulation, test, and performance-analysis tools for mobility, fading, congestion, and failure scenarios.
• Diagnose issues using logs, telemetry, packet captures, simulations, and hardware test environments.
