Core Development 

• Embedded Software Development: Architect/Design, write, debug, and maintain efficient software for real-time embedded systems, including mission critical Flight Software and communication with other space-specific software subsystems/modules, such as TTC (CCSDS protocol), Power, Thermal, GNC, FDIR, CFDP. 

• Communication Protocols and Specifications: Implement protocols used in space-grade software such as UART, CAN, SpaceWire, SPI, I2C, and Ethernet. Experience with Linux bridging, DSA (Distributed Switch Architecture), and L2 protocols such as RSTP/MSTP, HSR, or FRER for redundant network fabrics is highly valued 

• Networking and Avionics Fabrics: Design and implement L2 Ethernet networks for inter-board communication on spacecraft, including switch bring up, PHY configuration, and topology design. Configure and debug L2 redundancy protocols (RSTP, HSR, FRER) for fault-tolerant fabrics. Implement deterministic networking using TSN features where mission profiles require bounded latency. 

• Application Integration: Integrate and manage provided applications on top of the customized platform software. Design and bring up Ethernet-based avionics networks, including PHY/MAC initialization, switch configuration, and L2 redundancy protocols.  

• Operational Management: Design and implement efficient memory management, process management, software updates, reprogramming and power saving modes for embedded systems. Experience with multi-board Ethernet fabrics (mesh, ring, or tree topologies) for inter-subsystem communication is a plus.  

Testing and Support 

• Test Framework Development: Create and maintain automated testing frameworks for embedded systems, including HIL, SIL, PIL. 

• Support: Provide support for debugging of real-time and critical faults. 

• Debugging and Validation: Use tools like oscilloscopes, logic analyzers, and protocol analyzers to test and debug embedded software and hardware interfaces. 

Collaboration and Documentation 

• Hardware Interaction: Work closely with global software teams to contribute to the new designs and ensure seamless software-hardware integration. 

• Documentation: Prepare and maintain technical documentation.
