The Power Electronics & Controls Engineer – Microgrid Systems is responsible for the design, development, validation, and deployment of power electronic converters and their associated control algorithms for grid-connected and islanded microgrid and energy infrastructure systems. This role focuses on delivering robust, standards-compliant control solutions for applications such as BESS, PCS, inverters, solid-state transformers (SST), 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) deployed in microgrid and data center environments.
• 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 interconnections, 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 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
• Multi-converter parallel operation and power sharing

• Develop fast inner-loop and supervisory-level controls with appropriate bandwidth separation.
• Implement fault ride-through, black-start, islanding detection, and reconnection logic.
• 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.
• 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 boundaries.
• 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

• • • Strong fundamentals in:

      • 5 – 6 Years of relevant skills in the following areas:
      • Control theory (linear and non-linear systems)
      • Power electronics topology and converter design
      • Electrical power systems and grid dynamics

      Hands-on experience with:

      • Inverter-based resources (BESS, PV, PCS, UPS, STATCOM, SST, etc.)
      • Embedded control implementation (DSP, FPGA, or similar platforms)
      • Real-time simulation and HIL testing
      • Proficiency in modeling and simulation tools (e.g., MATLAB/Simulink, PLECS, PSCAD).
      • Understanding of grid dynamics, fault behavior, protection coordination, and microgrid operating modes.
      • Ability to interpret electrical schematics, control block diagrams, and system-level architecture.

• • Experience with microgrid controllers, EMS, or plant-level supervisory controls.
  • Exposure to utility interconnection processes and grid code compliance.
