Embedded Software Engineer – SDR Development

Do you want to help a small company make a BIG difference in space? Do you take ownership of your job and responsibility for your actions? Then come work for Red Canyon and help us continue our mission of helping humankind reach the stars! Here's a chance to work with an international aerospace company specializing in the production of small satellite platforms (from 6U CubeSats up to >300kg SmallSats) and innovative products to improve the comfort of space explorers. Thanks to its facilities and know-how, the company's activities follow the "all in-house" concept, which includes design, development, integration, qualification and operational services.    Working with leading international space agencies (e.g. NASA, ESA) and private companies, with an increasing focus on commercial partnerships. Our satellites have been selected for flagship missions such as NASA Artemis-1 and NASA DART. The company is advancing several major missions, such as a 40-satellite Earth observation constellation for integration into the Italian IRIDE program, as well as scientific missions such as LUMIO and HENON, and many other cutting-edge space projects.   IMPORTANT NOTICE   To conform to U.S. Government international trade regulations, the applicant must be a U.S. Citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State or U.S. Department of Commerce.   DUTIES & RESPONSIBILITIES   As an Embedded Software Engineer in our California team, you will report to the Chief of Telecom Engineering.  You will be responsible for leading the development of the UST-Lite software-defined radio (SDR). This role involves designing and implementing embedded C/C++ software for LEON3 softcore processors, architecting autoboot mechanisms for FPGA and soft processor initialization, and integrating SpaceWire and other communication interfaces.  You will take ownership of software system integration, debugging, and requirements traceability, while collaborating closely with FPGA engineers and quality assurance teams.  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.

REQUIRED QUALIFICATIONS AND SKILLS
