Role & Responsibilities
- Design, code, debug, and validate embedded firmware for elevator control units (ECUs), motor drivers, and safety interlocks using C/C++.
- Integrate real-time operating systems (RTOS) like FreeRTOS or Zephyr into microcontroller-based platforms (ARM Cortex-M, PIC, or STM32).
- Develop and maintain communication protocols (CAN, Modbus, RS485, I2C, SPI) for sensor networks and actuator coordination.
- Collaborate with mechanical and electrical teams to translate system requirements into optimized, deterministic firmware behavior under strict timing constraints.
- Conduct unit testing, code reviews, and hardware-in-the-loop (HIL) validation to ensure safety-critical compliance (EN 81, ISO 13849).
- Optimize memory footprint, power consumption, and interrupt latency for resource-constrained embedded environments.
