Job Description

Job Title: Control Engineer –Battery Energy Storage Systems (BESS)

Location: Bengaluru, India
Experience: 5–10 Years
Business Unit: PES – EPS
Segment: Utility-Scale & Commercial & Industrial (C&I;)

Role Summary

The BESS Electrical Design Engineer is responsible for the design Control Engineering for BESS Product Engineering team for Utility-scale and C&I; energy storage solutions. this role focuses on end-to-end ownership of control algorithms across the full product lifecycle—from concept and system design through validation, certification, and global deployment.

Key Responsibilities

Control System Design & Development

- Design, develop, and maintain control algorithms for Battery Energy Storage Systems, covering:
- Power and energy management
- Charge/discharge scheduling
- Voltage, frequency, and reactive power control
- Understand BMS design and step
- Control Interface with EMS, BESS controller, PPS and other required Equipment’s.

- Develop control strategies for utility-scale and C&I; applications, including:

- Frequency regulation and grid services
- Renewable energy integration
- Peak shaving and energy arbitrage
- Backup power and microgrid operation

- Implement control functions on real-time controllers and industrial-grade embedded platforms.

Data Analysis, Simulation & Validation

- Develop detailed control models using MATLAB/Simulink and equivalent tools.
- Support model-based development and auto-code generation workflows where applicable.
- Lead and execute SIL, HIL,



and system-level validation to ensure robust control performance under:
- Normal operating conditions
- Grid disturbances and abnormal scenarios
- Fault and recovery conditions

- Analyse performance metrics and continuously improve stability, accuracy, and efficiency of control algorithms.

System Integration & Cross-Functional Collaboration

- Work closely with PCS (Power Conversion System), BMS, EMS, system architecture, and grid compliance teams to ensure seamless integration.
- Ensure coherent control behaviour across:
- Inverter control layers
- Battery and protection constraints
- Site-level and fleet-level EMS commands

- Support Factory Acceptance Tests (FAT), Site Acceptance Tests (SAT), and commissioning activities globally as needed.

Standards, Compliance & Product Lifecycle

- Design controls compliant with global grid codes and utility interconnection requirements.
- Support certification and product qualification activities for different regions.
- Contribute to product roadmaps, reuse strategies, and platform standardization initiatives.
- Create and maintain high-quality technical documentation, control specifications, and design review artefacts in line with OEM processes.
- Participate in design reviews, failure analyses, and continuous improvement initiatives across product generations.
