Job description

KEY RESPONSIBILITIES:

Firmware Development: Design, write, and test low-level firmware in Embedded C for bare-metal architectures and Real-Time Operating Systems (FreeRTOS).

Peripheral Drivers: Develop and maintain low-level drivers and Board Support Packages (BSP) for timers, ADC/DAC, DMA, GPIO, and external Flash/EEPROM.

Wired Protocols: Implement, configure, and troubleshoot wired serial and fieldbus interfaces including UART, SPI, I2C, and CAN / RS-485.

Hardware Bring-Up: Lab Debugging: Bring up prototype boards and troubleshoot firmware-hardware issues using oscilloscopes, logic analyzers, multimeters, and JTAG/SWD debuggers.

Hardware Collaboration: Review hardware schematics, pinout mappings, and semiconductor datasheets in close collaboration with hardware design engineers.

MINIMUM REQUIREMENTS (MUST HAVE):

Experience: Minimum 3 years of hands‑on professional experience in embedded firmware development.

Core Programming: Proficient in software development skills (C/C++/Python/...)

Target Microcontrollers: Demonstrated hands‑on experience with at least one major MCU family: STMicroelectronics (STM32), NXP (LPC, Kinetis, S32K), or Renesas (RA, RX, RL78).

Communication Interfaces: Direct experience configuring and debugging wired buses: UART/USART, SPI, I2C, and CAN.

OS &Execution Models: Practical understanding of RTOS concepts (FreeRTOS tasks, queues, semaphores, mutexes) and bare‑metal superloops.

Lab Instrumentation:

Hands‑on experience using in‑circuit debuggers (J-Link, ST-Link, E2) and diagnostic

tools (logic analyzers, digital oscilloscopes).

Education:

Bachelor degree in Electronics & Communication Engineering (ECE),

Electrical & Electronics Engineering, (EEE),

Computer Engineering, or related technical field.
