## What they're looking for

- Design, implement, and maintain Zephyr RTOS firmware for platform management controller, including device drivers, subsystem integration, and application-level services
- Write and upstream-quality-review drivers against Zephyr's driver model — devicetree bindings, Kconfig, init levels and priorities, struct device APIs
- Deploy and maintain lightweight ML inference on target for anomaly detection and predictive fault analysis, own the path from trained model to running firmware
- Perform post-silicon bring-up: first-boot debug, clock and reset validation, bus enumeration, triage of RTL-versus-firmware ambiguity with design teams
- Debug hard problems using JTAG/SWD, ETM/ITM trace, protocol analyzers, and logic analyzers — including intermittent, timing-dependent, and multi-master bus failures
- Build and extend CI: unit tests, Twister test suites, hardware-in-the-loop regression, static analysis gates
