【Engineering & Research Division】Firmware Engineer
仕事概要
【About the Role】We are looking for a Firmware Development Engineer to join our Engineering & Research Division.
PowerX develops and delivers energy storage and power transfer solutions, including battery systems, charging systems, and related energy management technologies. Within the Engineering & Research Division, engineers work across hardware, embedded systems, cloud, software, and product lifecycle management to develop reliable and scalable products for real-world energy infrastructure.
This role will focus on firmware development for embedded systems used in our battery and energy-related products. You will work closely with hardware engineers, electrical engineers, and software engineers to design, implement, test, and improve firmware that supports stable product operation in demanding field environments.
【About Engineering & Research Division】
The Engineering & Research Division is responsible for end-to-end development of PowerX’s hardware and software systems for energy storage and power transfer solutions.
The division consists of approximately 50 specialists and is organized mainly into the following teams:
・Series Development: Responsible for prototyping, testing, validation, requirements engineering, product handover, product support, and commissioning.
・Advanced Engineering: Responsible for research and development of emerging technologies, including embedded systems, PCB design, model-based development, battery management, power conversion, digital twins, edge computing, cloud solutions, and AI/ML-based optimization.
・Product Lifecycle Management: Responsible for managing product and project lifecycles across quality gates, sourcing, value engineering, manufacturing, and after-sales activities.
You will work in a diverse engineering environment with members from various technical and cultural backgrounds. The team values autonomy, ownership, and hands-on problem solving, and engineers are encouraged to take initiative in shaping technical decisions.
【Responsibilities】
・Develop embedded firmware for microcontroller-based systems used in PowerX’s battery and energy-related products.
・Design and implement low-level drivers and interfaces, such as UART, SPI, I2C, ADC, PWM, GPIO, and timers.
・Create firmware specifications based on datasheets, reference manuals, schematics, and product requirements.
・Test, debug, and improve firmware in close collaboration with hardware, electrical, and software engineers.
