Battery Management Firmware Engineer

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
• Strong 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.
