A DAY IN THE LIFE:

The Embedded Software Engineer III plays a key role in developing software solutions for satellite avionics and payload data processing systems. This position involves creating real-time system monitoring and power management software, preparing Linux board support packages for customer flight applications, and working with a variety of embedded systems, sensors, communication buses, radios, and communications security (COMSEC) equipment. Close collaboration with hardware and FPGA engineers is essential to deliver rugged, reliable, and integrated Low-Size, Weight, and Power (Low-SWaP) products to aerospace customers.

Active U.S. Security Clearance Is Required.

WHAT YOU'LL DO:

• Develop Embedded Software Systems: Design and implement embedded C/C++ software for multi-core processors and FPGA-integrated systems (Xilinx, Microchip, Vorago), targeting ARM Cortex and RISC-V architectures.
