Key Responsibilities The Power Electronics and Control Design Engineer is responsible for the design, development, validation, and deployment of power electronic converters and their associated control algorithms for grid-connected and islanded energy systems. This role focuses on delivering robust, standards-compliant control solutions for applications such as BESS, inverters, converters, and microgrid systems, while collaborating closely with hardware, firmware, protection, and systems engineering teams. Main Accountabilities Own the control system architecture and design for power electronic converters (AC/DC, DC/DC, DC/AC). Develop real-time control algorithms to ensure stability, performance, and grid compliance under normal and abnormal operating conditions. Ensure designs meet functional, performance, reliability, and regulatory requirements across the product lifecycle. Support system-level integration of power converters into microgrids, utility, data center, and industrial environments. Drive technical decisions related to control strategy trade-offs, dynamic performance, and grid interaction behavior. Provide technical leadership during product development reviews, design validation, and customer or third-party technical discussions. Contribute to the continuous improvement of engineering processes, modeling practices, and design standards. Key Activities and Responsibilities Design and implement control algorithms for: Grid-forming, grid-following, and grid-supporting converters Voltage, current, power, frequency, and DC-link regulation Droop control, virtual inertia, PLL-based synchronization Develop fast inner-loop and supervisory-level controls with appropriate bandwidth separation. Implement fault ride-through, black-start, islanding, and reconnection logic. Minimum Qualifications Strong fundamentals in: Control theory (linear and non-linear systems) Power electronics and electrical power systems Hands-on experience with: Inverter-based resources (BESS, PV, PCS, UPS, STATCOM, etc.) Embedded control implementation Proficiency in modeling and simulation tools (e.g., MATLAB/Simulink/PLECS). Understanding of grid dynamics, fault behavior, and protection coordination. Ability to interpret electrical schematics and system-level architecture. Collaborate with system architects, EMS/SCADA teams, protection engineers, and product managers. Support proposal, concept, and customer-specific solution development with technical input. Provide clear documentation of control logic, interfaces, assumptions, and limitations. Validate control performance through: Software-in-the-Loop (SIL) Hardware-in-the-Loop (HIL) Factory and site acceptance testing (FAT/SAT) Soft Skills & Behavioral Competencies Systems thinker – able to balance control performance, hardware limits, grid requirements, and operational constraints. Structured problem solver – approaches complex technical problems methodically and transparently. Technical communicator – can clearly explain control concepts to non-controls experts, customers, and leadership. Collaborative mindset – works effectively across disciplines and organizational Ownership & accountability – takes responsibility for technical outcomes from concept through deployment. Adaptability – comfortable working in evolving architectures and handling ambiguous requirements. Attention to detail – maintains rigor in documentation, testing, and validation. Preferred Qualifications Experience with microgrid controllers, EMS, or plant-level supervisory controls. Exposure to utility interconnection processes and grid code compliance. Advanced degree (M.S. or Ph.D.) in Electrical Engineering or related field.
