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. ## Description 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. 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
