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., Applicants for employment at Blue Origin must be a U.S. citizen or national, U.S. permanent resident (i.e. current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum. Background Check * Required for all positions: Blue's Standard Background Check * Required for Certain Job Profiles: Defense Biometric Identification System (DBIDS) background check if at any time the role requires one to be on a military installation * Required for Certain Job Profiles: Drivers who operate Commercial Motor Vehicles with a Gross Vehicle Weight (GVW), Gross Vehicle Weight Rating (GVWR) or combination of power unit and trailer that meets or exceeds 10,001 lbs. and/or transports placardable amounts of hazardous materials by ground in any vehicle on a public road while in commerce, may be subject to additional Federal Motor Carrier Safety Regulations including: Driver Qualification Files, Medical Certification (obtained before onboarding), Road Test, Hours of Service, Drug and Alcohol Testing, vehicle inspection requirements, CDL requirements (if applicable) and hazardous materials transportation/shipping training. * Required for certain Job Profiles: Ability to obtain and maintain Merchant Mariner Credential, which includes pre-employment and random drug testing as well as DOT physical ## Related Videos - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) - [Leveraging Large Language Models for Legacy Code Translation: Challenges and Solutions](https://www.wearedevelopers.com/videos/1157-leveraging-large-language-models-for-legacy-code-translation-challenges-and-solutions) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Strange New Worlds: shaping the future of the digital age](https://www.wearedevelopers.com/videos/677-strange-new-worlds-shaping-the-future-of-the-digital-age) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) ## Related Articles - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Dev Digest 134 - Where pixels sing?](https://www.wearedevelopers.com/magazine/477-dev-digest-134-where-pixels-sing) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [7 Important Tips That Every Software Developer Should Know](https://www.wearedevelopers.com/magazine/101-7-important-tips-that-every-software-developer-should-know) - [Best Countries for Software Engineers](https://www.wearedevelopers.com/magazine/267-best-countries-for-software-engineers) - [How software is steering vehicle technology](https://www.wearedevelopers.com/magazine/515-how-software-is-steering-vehicle-technology)
