Sr Software Engineer, Embedded Flight Software

York isseeking aSenior Embedded Flight Software Engineer to design, develop, test, and deliver mission-critical software for spacecraft systems. This role focuses onreal-time and embedded Linux-based flight software, enabling reliable command, telemetry, networking, and autonomy across on-orbit vehicles.

The ideal candidate is ahands-on engineer with strong systems thinking who canoperateacross the full lifecycle—from architecture and development through integration, test, and on-orbit support.

Not all skills below are required, we encourage you to apply if you have an interest in learning!

• Design and develop embedded flight software in C/C++ for spacecraft systems
• Design, develop, and maintain reliable embedded flight software for resource-constrained, safety-critical systems.
• Develop and debug multithreaded software, including thread synchronization,interprocesscommunication, race-condition prevention, and deadlock avoidance.
• Integrate software with hardware components(OBCs, radios, payloads) in HITL andflatsatenvironments
• Develop and execute test strategies(unit, integration, system, and mission-level testing)
• Supporton-orbit operations, debugging, and anomaly resolution
• Translate Interface Control Documents (ICDs), system requirements, and hardware specifications into robust software interfaces and implementations.
• Collaborate across platform, applications, mission ops, and hardware teams
• Experience with HITL,flatsat, or system-level test environments
