Embedded Linux
Embedded Linux is the use of the Linux operating system in resource-constrained devices such as routers, cameras, industrial controllers, automotive systems, and IoT hardware. It involves cross-compiling the kernel, configuring bootloaders, building minimal root filesystems, and writing device drivers for specific hardware targets. Core toolchains include Buildroot for simpler custom images and the Yocto Project for production-grade, reproducible embedded distributions.
As AI inference moves to the edge, every smart sensor, autonomous vehicle ECU, and industrial robot runs a stripped-down Linux stack — making embedded Linux engineers essential at companies deploying on-device models. The full merge of the PREEMPT_RT real-time patch into the mainline Linux kernel in 2024 has intensified demand for engineers who can tune latency-sensitive embedded systems. Hardware AI accelerators (NPUs, TPUs) require custom kernel drivers and BSPs, skills that sit squarely in embedded Linux territory.
