• Lead technically within an autonomous squad, plan, de-risk, review designs, and ship.
• Integrate edge components (sensors, accelerators, connectivity) and make data flow smoothly to the cloud.
• Build for reliability: tracing, logging, observability, and failure-safe update paths.

What you bring...

• Background with C/C++ in user space and BSP layers.
• Strong experience in embedded Linux on product hardware: board support packages, bring-up, integration, and debugging.
• Solid knowledge of RTOS on microcontrollers (FreeRTOS, Zephyr or similar).
