Staff Embedded Platform Engineer

You will own core platform firmware for a distributed embedded system of multiple microcontrollers, building reusable drivers, services, and test infrastructure on Zephyr RTOS. This is a platform-facing role. You'll close real gaps across the stack, from standing up a device watchdog/supervision design, to building driver test suites for our automotive Ethernet PHY driver, to hardening real-time Ethernet and custom serial protocols, so application teams can build on a stable, scalable foundation.
