Principal Power Architect

Areas of Responsibilities:

• Architect advanced high-voltage, high-power DC-DC converter topologies (e.g., LLC, PSFB, interleaved buck/boost, flyback) specifically tailored for use with SiC/GaN-based power modules in energy systems.
• Define scalable and modular power architectures that supply and interface with wide-bandgap-based converters for solar inverters, battery energy storage systems (BESS), grid-tied systems, and DC fast chargers.
• Lead design of isolated and non-isolated DC-DC supplies with wide input/output ranges (e.g., 100 V–1500 V), supporting fast transient loads and high switching speeds inherent to SiC/GaN technologies.
• Own development of analog and digital control systems, ensuring fast, stable response and integration with wide-bandgap switching dynamics.
• Direct the selection and specification of magnetics, isolation techniques, and thermal strategies suitable for high-frequency, high-efficiency power stages.
• Ensure full compliance with safety (UL, IEC), EMI/EMC (CISPR/IEC 61000), and grid-interconnect standards relevant to energy platforms.
• Collaborate across functions—including SiC/GaN switch designers, packaging engineers, and system architects—to co-optimize performance and reliability.
• Provide technical leadership, mentoring, and system-level oversight throughout architecture, design, validation, and productization.
• Drive IP generation, architecture documentation, and technology roadmaps aligned with the company’s energy product strategy.
