Job description

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. • Strong proficiency in: • Control system theory and practical implementation • MATLAB/Simulink modeling and simulation • Real-time or embedded control systems • Solid understanding of: • Inverter-based power conversion systems • Battery operational limits and interaction with control layers • Coordinated control between BMS, PCS, and EMS • Experience with SIL / HIL testing and real-time simulators. • Familiarity with industrial communication protocols (e.g., CAN, Modbus). Grid & System Knowledge • Hands-on experience with utility and C&I grid-connected systems. • Strong understanding of: • Voltage and frequency regulation • Grid-following and grid-supportive control strategies • Islanding, reconnection, and abnormal grid behavior • Exposure to international standards and grid codes relevant to stationary BESS. Preferred Qualifications • Bachelor’s or Master’s degree in Electrical Engineering, Control Systems, Power Electronics, or related field. • Experience working within a large OEM or global product organization. • Knowledge of functional safety, redundancy, and fault-tolerant control concepts. • Exposure to multi-site development, global product deployment, or fleet-scale energy systems. • Experience supporting long-life infrastructure products with high reliability and availability requirements. Professional & Behavioral Competencies • Strong system-level thinking and analytical skills. • Ability to work within structured engineering processes and quality systems. • Effective communication with cross-cultural and cross-functional teams. • Ownership mindset with focus on reliability, safety, and long-term product performance.
