Job Summary

Position - BMS LEAD

LOcation - Bangalore

Key Responsibilities

Develop end-to-end BMS architecture for utility-scale BESS (cell module rack system).
Define hardware software communication sensing protection and redundancy requirements.
Select topology: centralized / modular / distributed BMS design for containerized BESS.
Own CAN bus RS485 Ethernet Modbus or proprietary protocol design.
Allocate safety functions between BMS PCS EMS and system controllers.

Lead development of algorithms for SOC SOH SOE estimation
Cell balancing strategies (passive/active)
Fault detection thermal derating voltage/current limits
Aging degradation models
Define charge/discharge control logic aligned with grid-connected use cases (frequency regulation peak shaving energy shifting hybrid storage).
Ensure accurate measurement systems for voltage current temperature isolation resistance and HVIL.

Drive compliance with battery safety standards
Ensure safety design for cell over-temp thermal runaway overcurrent isolation loss and fire-event interaction.
Work closely with thermal fire safety and FMEA teams to ensure TR propagation mitigation strategies.
Define safety matrix and functional safety requirements

Lead selection of BMS ICs microcontrollers isolators ADCs and cell monitoring chips.
Guide firmware development for Sensor polling CAN communication Protection logic Diagnostics
Fail-safe modes Review PCB design for module BMS rack BMS and system controller.

Integrate BMS with Pack/rack design (electrical mechanical) PCS / inverter EMS / site controller HVAC/thermal system Fire detection/suppression system
Define interface control documents (ICDs) and communication protocols.
Lead root-cause analysis (RCA) for field issues involving SOC drift cell imbalance thermal faults and communication failures.
Develop test plans for HIL/SIL testing Pack/rack functional tests Environmental testing Aging and cycle tests

Lead FAT SAT and prototype validation with engineering and field teams.
Ensure BMS behaviour under fault conditions (HV isolation failure over-temp rapid charge/discharge spikes).
Support UL/IEC certification testing and documentation.

Guide BMS improvements based on field performance degradation data and warranty feedback.
Manage vendor BMS qualification (if using third-party BMS platforms).
Own documentation: design requirements schematics firmware release notes safety analyses.
Mentor team members and guide development of next-generation BMS roadmap.

Required Qualifications

Bachelors or Masters in Electrical / Electronics / Embedded Systems / Power Engineering or similar.

Advanced degree in Battery Technology is a plus.

Technical Skills

Deep knowledge of Li-ion cell chemistry (LFP/NMC) operating envelopes safety limits.
Expertise in BMS algorithms (SOC/SOH/SOE) thermal derating and protection logic.
Proficiency in CAN Modbus serial communication and real-time embedded systems.
Experience with HIL/SIL tools (dSPACE NI Opal-RT Typoon).
Understanding of pack architecture high-voltage systems and thermal management.
Experience with UL / IEC certification for battery systems.

Experience

10 15 years in BMS development for BESS EV UPS or industrial battery systems.
Minimum 3 years leading BMS hardware/firmware teams.
Experience with utility-scale (1 200 MWh) BESS systems is strongly preferred.
Field or commissioning experience is a plus.
