About The Position

The Senior Embedded Software Engineer — Linux, SoC & Hardware Integration is the technical bridge between custom hardware and application software. This role turns advanced hardware platforms, FPGA fabric, ASICs, accelerators, and other memory-mapped peripherals into reliable capabilities that higher-level software teams can build on. This position supports the rapid development of next-generation, AI-enabled hardware and sensor platforms for counter-UAS (cUAS) and multi-sensor applications. The engineer will bring up embedded Linux systems, configure bootloaders and device trees, integrate custom hardware interfaces, and enable high-throughput data paths using DMA, PCIe, AXI, interrupts, and shared memory. Working closely with electrical, FPGA, RF, DSP, and application software engineers, this role helps transform new hardware concepts into modular, mission-ready capabilities. The ideal candidate will be excited to work in a fast-moving R&D environment, solve challenging hardware/software integration problems, and help build technology that moves quickly from concept to real-world impact.
