Satellite Flight Software Engineer III - 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!

* This position is part of Blue Origin's Tera Wave business unit, a newly announced satellite communications network designed to deliver symmetrical data speeds of up to 6 Tbps anywhere on Earth. Tera Wave consists of 5,408 optically interconnected satellites in low Earth orbit (LEO) and medium Earth orbit (MEO), providing enterprise-grade connectivity for critical operations.

We are seeking a Satellite Flight Software Engineer III to design, develop, and verify applications for Tera Wave's satellite flight software subsystem. This role will be instrumental in building robust, scalable flight software to support the expansion of Tera Wave into a 5,408-vehicle constellation. The ideal candidate is a hands-on engineer with experience developing reliable, mission-critical software for onboard spacecraft avionics systems with emphasis on command and data handling (C&DH), telecommand and telemetry processing, spacecraft time management, hardware I/O interfaces, and cybersecurity.

Responsibilities include but are not limited to:

* Design, develop, and implement flight software for Tera Wave's command and data handling (C&DH) software, including command routing, onboard data management, and telemetry generation

* Develop telecommand and telemetry processing software for uplink command validation, scheduling, and execution, and onboard health and status data collection and downlink management

* Develop spacecraft time management software including onboard time correlation, synchronization with GPS/GNSS time references, and precision timing distribution across vehicle subsystems

* Create and maintain software interfaces between C&DH and other spacecraft subsystems to support safe and secure vehicle operations

* Collaborate with hardware, systems, and autonomy engineers to define software requirements, interfaces, and behavioral boundaries across subsystems

* Develop and integrate simulation environments and models to test FSW across a range of nominal and off-nominal operational scenarios

* Support software architecture, design reviews, and systems engineering trade studies

* Participate in software integration, verification, and validation testing including software-in-the-loop (SIL) and hardware-in-the-loop (HIL) environments

* Support on-orbit operations and troubleshooting of deployed spacecraft

* Mentor junior engineers and contribute to team technical development

Minimum Qualifications:

* Bachelor's degree in Computer Science, Software Engineering, Aerospace Engineering, or related technical field

* 7+ years of experience in spacecraft flight software or embedded software development

* Strong programming skills in C, C++, and Python

* Experience with real-time operating systems (RTOS) such as Linux, QNX, VxWorks, RTEMS or equivalent

* Experience developing software for one or more spacecraft avionics functions such as C&DH, telecommand and telemetry processing, or hardware I/O management

* Familiarity with CCSDS standards for spacecraft telecommand and telemetry processing

* Familiarity with cybersecurity principles for space systems including secure boot, command authentication, or encrypted communication links

* Experience with software unit testing frameworks such as Google Test or equivalent for embedded C/C++ environments

* Experience with inter-process communication (IPC) mechanisms including sockets, shared memory, message queues, or publish-subscribe middleware

* Experience with cross-compilation tool chains and embedded Linux build systems such as CMake, Make, Yocto, or Buildroot

* Experience with software lifecycle, configuration management (Git), CI/CD, and verification/validation practices for mission-critical embedded software systems

* Experience with communication protocols such as TCP/IP, UDP, CAN, I2C, SPI, and RS-422/485

* Familiarity with static analysis tools and flight software coding standards such as MISRA C/C++

Preferred Qualifications:

* Master's degree in Computer Science, Software Engineering, or related field

* Experience with on-orbit spacecraft operations or satellite constellation management

* Experience with over-the-air (OTA) software updates

* Experience with onboard time management, precision timing interfaces, or GPS-disciplined time synchronization

* Experience developing flight software for fault-tolerant or redundant avionics architectures, such as dual-string or voting-based system designs

* Familiarity with NASA cFS, F Prime, or similar flight software frameworks

* Familiarity with spacecraft FDIR and autonomy software components and their interfaces

* Understanding of radiation…
