Software Development Engineer III – MAC Control Plane – TeraWave

Application close date:

At Blue Origin we envision millions of people living and working in space for the benefit of Earth. Were 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 Software Development Engineer III on the TeraWave Software and Networking Team you design implement and test control-plane software for a custom Media Access Control (MAC) layer supporting Blue Origins TeraWave network.

The MAC control plane governs radio-resource allocation link establishment scheduling quality of service link adaptation and mobility across dynamic satellite-to-ground connections. You contribute to purpose-built MAC protocols and control mechanisms that address the scale propagation characteristics mobility and availability requirements of the TeraWave architecture.

You work closely with senior software engineers and engineers across the PHY modem networking platform and systems teams to develop a high-throughput predictable-latency wireless stack designed specifically for space-based communications.

Responsibilities

• Design implement and test MAC control-plane software for point-to-point and point-to-multipoint satellite communication links.

• Develop components of TDMA demand-assigned multiple access admission-control scheduling and radio-resource-allocation systems.

• Implement protocol 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.

• 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.

Basic Qualifications

• Bachelors degree in Computer Science Computer Engineering Electrical Engineering or related technical field.

• Four or more 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.

Preferred Qualifications

• Experience developing MAC or link-layer software for satellite non-terrestrial cellular fixed wireless or other communication platforms.

• Knowledge of TDMA DAMA OFDMA radio-resource management adaptive modulation and coding ARQ or HARQ admission control or QoS scheduling.

• Experience integrating software with PHY implementations FPGAs DSPs modems or custom SoCs.

• Experience with multithreaded asynchronous or event-driven software architectures.

• Experience with simulation and analysis environments such as ns-3 MATLAB Python or custom discrete-event simulators.

• Experience with high-performance packet-processing technologies such as DPDK VPP eBPF or hardware packet-processing engines.

• Experience developing systems that operate under variable latency constrained bandwidth partial connectivity or rapidly changing network conditions.
