Embedded Software Engineer – SDR Development

Specific duties include (but are not limited to):

• Develop embedded C/C++ & Python software for LEON3 softcore processors on Xilinx Kintex UltraScale and Microchip ProASIC3 platforms;
• Architect and implement software mechanisms to support autoboot loading of FPGAs and LEON softcore processors;
• Develop application software for SDRs to perform radio hardware configuration and initialization, protocol control and management (e.g. CCSDS Proximity-1), and supervisory functions;
• Collaborate with FPGA engineers to embed softcore IP and integrate interfaces;
• Define and implement commands, telemetry, and configuration mechanisms for multiple SDR operational modes; 
• Implement and test SpaceWire cores and protocol handling, with future contributions to Ethernet and CAN interface implementation;
• Set up and maintain Linux build environments for cross-compilation using Gaisler RTEMS and Bare-C Cross Compiler (RCC/BCC) toolchains;
• Take full ownership of integration and debugging of software/firmware interactions, and system bring-up;
• Perform system integration, HW/SW troubleshooting, and end-to-end verification;
• Review system-level requirements and generate, maintain, and verify lower-level software requirements to ensure compliance and traceability;
• Work closely with quality assurance and lead growth initiatives for software quality management;
• Develop and maintain software design documentation, including any simulators/emulators used for development;
• Develop support applications (EGSE) for avionics system (AVS) interface simulation;
• Document build, boot, and operational procedures clearly for internal and external stakeholders;
• Support next-generation processor and FPGA architecture updates.
