Senior Wireless Software Engineer - MAC Control Plane - TeraWave

Application close date:

Applications will be accepted on an ongoing basis until the requisition is closed.

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We're 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!

Blue Origin is pioneering the future of space-based communications with Tera Wave, a revolutionary satellite communications network designed to deliver symmetrical data speeds of up to 6 Tbps anywhere on Earth. This multi-orbit constellation will consist of optically interconnected satellites in low Earth orbit (LEO) and medium Earth orbit (MEO), providing enterprise-grade connectivity for critical operations worldwide.

As a Senior Software Engineer on the Tera Wave Software and Networking Team, you design and implement control-plane software for a custom Media Access Control (MAC) layer supporting Blue Origin's Tera Wave 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. As such, you help develop purpose-built MAC protocols and control mechanisms that address the scale, propagation characteristics, mobility, and availability requirements of the Tera Wave architecture.

You work closely with PHY, modem, networking, platform, and systems engineers to deliver a high-throughput, predictable-latency wireless stack designed specifically for space-based communications.

Responsibilities

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

• Develop scalable TDMA, demand-assigned multiple access, admission-control, and resource-allocation algorithms for many beams, links, 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 and modem teams.

• Define and implement 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, accounting for control latency, stale state, partial 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 operational deployment.

Basic 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.

Preferred Qualifications

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

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

• Experience integrating control-plane software with PHY implementations, FPGAs, DSPs, modems, or custom SoCs.

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

• Experience using simulation and…
