# Lead Firmware Engineer - Bess

Kimbal is developing its own Battery Management System (BMS) and Energy Management System (EMS) for utility-scale Battery Energy Storage Systems (BESS). We are looking for a Firmware Engineer to write the embedded software and battery algorithms that protect our systems and extract the most usable energy from every cell. You will work from bare-metal drivers to safety logic and state estimation, in close partnership with the hardware, controls and systems engineers, and see your code run on systems deployed on India's grid. Key Responsibilities: Develop BMS firmware across the module, rack and system tiers on embedded microcontrollers: drivers, RTOS integration, bootloader and secure firmware-update modules. Implement battery protection and safety logic: over/under-voltage, current and temperature protection, isolation-fault detection, sensor-failure handling and thermal-event response. Implement contactor and pre-charge control, rack paralleling, and fault diagnostics with event logging. Implement and tune battery algorithms: state-of-charge, state-of-health and state-of-power (power limit) estimation, and cell, module and rack balancing. Parameterise cell models from Kimbal's c
