Senior Wireless Software Engineer – MAC Data 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 Senior Software Engineer on the TeraWave Software and Networking Team you design and implement the real-time data-path software for a custom Media Access Control (MAC) layer supporting Blue Origins TeraWave network.

The MAC data plane translates scheduling and resource-allocation decisions into precisely timed radio transmissions and receptions. You build the high-performance software that moves customer traffic between network interfaces MAC queues modem hardware and the physical layer while meeting stringent throughput latency timing and reliability requirements.

You collaborate with MAC control-plane PHY modem FPGA networking platform and systems engineers to deliver a purpose-built wireless stack for high-capacity satellite links operating across dynamic low Earth orbit environments.

Responsibilities

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

• Translate MAC scheduling and resource-allocation decisions into timed transmit and receive operations executed by modem and PHY hardware.

• Develop packet-processing pipelines and manage queues buffers flow control prioritization and congestion-handling across the data path.

• Develop data-path support for retransmission sequence tracking duplicate detection loss recovery and in-order or selective packet delivery.

• Integrate MAC data-plane software with PHY implementations modem firmware FPGAs DMA engines network interfaces and custom SoCs.

• Optimize memory movement and packet processing using zero-copy buffers scatter-gather I/O batching lock-free queues and hardware offload.

• Build telemetry and diagnose timing synchronization performance and integration issues using packet captures traces and hardware test environments.

• Deliver MAC data-plane capabilities from architecture and prototyping through hardware integration performance qualification and operational deployment.

Basic Qualifications

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

• Seven or more years of software-development experience in wireless embedded communication systems or high-performance packet processing.

• Advanced proficiency in C or C with concurrent timing-sensitive software in Linux real-time Linux or RTOS environments.

• Experience implementing high-throughput or low-latency data paths communication protocols device interfaces or packet-processing systems.

• Experience integrating and debugging software with embedded hardware network devices modems FPGAs or communication-system components.

Preferred Qualifications

• Experience developing MAC or link-layer data-plane software for satellite cellular fixed wireless cable Wi-Fi or other communication systems.

• Knowledge of TDMA DAMA OFDMA framing segmentation and reassembly ARQ or HARQ QoS scheduling and radio-link operation.

• Experience interfacing with FPGAs DSPs DMA engines modem firmware network-interface hardware or custom SoCs.

• Experience with zero-copy packet processing shared-memory architectures scatter-gather I/O lock-free data structures and cache-aware software design.

• Experience with high-performance networking frameworks such as DPDK VPP AFXDP iouring or similar user-space packet-processing technologies.

• Experience with hardware and software synchronization precision timing timestamping and execution against time-based transmission schedules.

• Experience using protocol analyzers packet captures performance profilers logic analyzers or hardware-in-the-loop test environments.
