Senior Flight Software Engineer - TT&C - Project Sunrise - Orbital Data Centers

As a Senior Flight Software Engineer for Telemetry, Tracking, and Command (TT&C), you will be responsible for developing the software that serves as the primary communications link to our satellites. You will own the entire TT&C software stack, from the low-level drivers that interface with the radio hardware to the application-level logic that packetizes and routes data. A key advantage of this role is the ability to begin development immediately on commercial-off-the-shelf (COTS) transponders, allowing you to build and validate the core software stack before the final flight hardware is available. This is a critical, hands-on role for an engineer who excels at integrating hardware and software to create a robust and reliable communications system.

Responsibilities include but are not limited to:

• Design, develop, and verify the flight software for the Telemetry, Tracking, and Command (TT&C) subsystem.

• Develop and maintain the device drivers and software interfaces for the spacecraft’s radio transponders.

• Implement the command processing logic, including command decoding, validation, and execution.

• Build the telemetry and data handling software, responsible for collecting, packetizing, and downlinking vehicle state-of-health and mission data.

• Develop and execute test plans for the TT&C software, initially using commercial transponders and progressing to flight hardware in an integrated lab environment.

• Collaborate with the ground software and mission operations teams to ensure end-to-end compatibility and performance of the communications link., 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.

• Strong programming skills in C/C++ in a real-time, resource-constrained environment (RTOS or bare-metal).

• Demonstrated experience developing software for communication systems, including work with radio hardware, modems, or transponders.

• Experience writing low-level device drivers for interfaces such as SPI, I2C, or UART.

• Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

Preferred Qualifications:

• Master’s degree or PhD in a relevant field.

• Deep understanding of RF communications, digital signal processing, and communication protocols.

• Experience with spacecraft communication protocols, such as CCSDS (Space Packet Protocol, TM/TC Space Data Link, and SDLS security).

• Hands-on experience testing and debugging hardware/software interfaces using lab equipment (e.g., spectrum analyzers, oscilloscopes).

• Familiarity with software-defined radios (SDR).

• Familiarity with software assurance standards such as NASA-STD-8739.8, NPR 7150.2, ECSS-Q-ST-80C, or equivalent (e.g., DO-178C), and with embedded coding standards such as the JPL Institutional Coding Standard, MISRA C/C++, or CERT C/C++.

• A passion for building and testing the end-to-end communications chain, from the operator’s keyboard to the spacecraft and back.

• Travel may be required up to 10% of the time.

• Relocation assistance available.
