Build battery-management firmware for Foreseeson Technology’s high-voltage ESS, using C/C++ and communication protocols across connected devices. As an Embedded Systems Engineer, you will develop software for battery status acquisition, charge and discharge sequencing, and system-state management. You will integrate battery controllers, power electronics, and control devices while addressing safety requirements. The project combines battery management, power conversion, embedded control, and monitoring.

Key Responsibilities
Develop battery status acquisition and charge sequencing firmware Control contactor, pre-charge, fault, and operating-state interfaces Integrate existing battery controllers through documented protocols Diagnose timing, bus, signal,



and interoperability problems Support protection interlocks, controlled shutdown, and emergency-stop interfaces

Requirements:
At least three years of embedded firmware development experience Robust embedded C/C++ and/or Python programming skills Practical CAN, RS-485, UART, I²C, and SPI experience Experience with firmware debugging tools and development environments Knowledge of Linux-based systems and real-time operating systems Use battery communication, fault handling, and embedded debugging skills to coordinate Foreseeson’s high-voltage ESS controls.
