This position sits close to the embedded world, but it isn't traditional microcontroller firmware work. You'll own the operating system foundation and platform layer of our IoT devices - building and evolving our next-generation embedded Linux image - and develop the Python application layer that runs on top of it, inside our dockerized main application.
You'll work down at the OS and hardware boundary while shipping features up in the application layer. Typical areas include:
Designing and maintaining our Yocto-based Linux distribution for ARM devices with limited compute
Security on device, inter-process communication, networking, scheduling, observation
Over-the-air (OTA) updates for both the OS and applications
Integrating peripherals - watchdog, modem, AI accelerator - and improving their observability
Bridging the system layer and the application layer through Python and Bash
The work spans from driver- and kernel-level integration in C/C++, to adapting our Linux distribution with Yocto to the underlying hardware layer, to debugging system-level failures such as memory leaks, up to writing the Python software that turns hardware capabilities into product features.
You will be expected to pass a live coding interview for this role.
