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.
Required Skills & Experience
Technical Expertise
- 5–10 years of experience in control engineering for power electronics, grid-connected systems, or energy storage products.
