This Embedded Software Engineer role at Leidos involves designing and developing high-performance embedded software for custom System-on-Chip (SoC) hardware in electronic warfare applications. You will write low-level C/C++ code for multi-core systems (DSP, ARM, RISC-V), perform hardware-software co-design and validation, and build software development kits for end users. The position requires 4+ years of embedded systems experience, deep understanding of hardware architectures, and proficiency in reading datasheets, test-driven development, and real-time operating systems.
