Summary:

Hitachis R&D Center located in Santa Clara CA serves as a pivotal technology hub to support Hitachis global Social Innovation business. The Mobility Innovation Laboratory (MIL) prototypes and validates embedded AI and system solutions to solve real problems in industrial this position you will implement embedded software primarily on STM32 MCUs and M5Stack (ESP32-based) addition you will build a reliable on-device system that connects sensor inputs (microphone and camera) to on-device AI inference on real hardware.

In this project the lead engineer will define the system specifications and develop the AI models. You are expected to understand these specifications and AI models and then implement test and improve the firmware/device application while considering embedded constraints such as memory latency power and communication quality.

This role is a great opportunity to strengthen your practical skills in embedded AI through development aimed at real demos and on-site deployment.

Responsibilities:

• Develop embedded code on STM32 using tools such as CubeMX CubeIDE (interrupts timers DMA etc.) including communication processing (Wi-Fi / BLE / UART / USB) and device control.

• Implement applications on M5Stack/ESP32 (Arduino and/or ESP-IDF) including communication processing (Wi-Fi / BLE / UART / USB) and device control.

• Implement sensors/peripherals (I2C / SPI / UART / ADC / PWM etc.) data acquisition and preprocessing.

• Integrate provided AI models based on the specifications (inference runtime and I/O pipelines).

• Optimize under MCU constraints (reduce memory usage improve speed and consider quantization or fixed-point implementation when needed).

• Create test and validation materials (simple automation reproduction steps documentation).

• Communicate risks alternatives and design trade-offs with the lead engineer/hiring manager.

Required Qualifications:

• M.S. in Computer Engineering Computer Science or a related field.

• 2 years of embedded software development experience in C/C.

• Development experience with STM32 microcontrollers (CubeMX CubeIDE X-CUBE-AI etc.).

• Development experience with M5Stack/ESP32 (Arduino or ESP-IDF; ESP-IDF is preferred).

• Ability to understand specifications and convert them into an implementation plan with strong communication skills to collaborate with stakeholders.

• Experience integrating/optimizing on-device AI inference (e.g. X-CUBE-AI or equivalent).

• Experience with profiling/optimization (memory speed) quantization fixed-point.

• Experience with embedded testing and documentation for reproducibility.
