Job description

Principal Power Architect :

Purpose :

We are seeking a highly experienced Principal Power Management Architect to lead the design and system architecture of next-generation Power Management / Conversion platforms for our Energy business. This includes high-reliability power conversion for renewable energy systems, energy storage, grid-tied converters, and distributed energy infrastructure. The ideal candidate will define scalable power architectures that meet demanding efficiency, thermal, and regulatory requirements for high-voltage, high-power energy systems.

Areas Of Responsibility :

  • 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.

Technical Skills :

  • Expert in DC-DC converter topologies : Buck, Boost, Flyback, Forward, PSFB, LLC, Interleaved, Multi-phase.
  • Expertise in wide-bandgap semiconductors (SiC / GaN) and digital power control.
  • Proficiency in control loop design : voltage / current-mode control, Type II / III compensation, digital control.
  • Strong knowledge of magnetics design : transformer and inductor design for high efficiency and low EMI.
  • Proficient in high-voltage isolation techniques and safety-compliant designs (UL1577, IEC 62109).
  • Deep understanding of EMI / EMC suppression, filter design, and compliance to IEC 61000, CISPR.
  • Skilled in thermal modeling, derating, and power density optimization for harsh environments.
  • Simulation tools : LTspice, SIMPLIS, PSIM, PLECS, MATLAB / Simulink.
  • Familiarity with digital power controllers, firmware interaction, and telemetry features.
  • Knowledge of grid interface standards, MPPT algorithms, and power module integration.
  • Knowledge of MPPT, multi-port converters, and BMS interfacing

    • Behavioral Skills :

  • Strategic Thinking : Ability to define long-term technology direction aligned with energy market trends.
  • Technical Leadership : Influences and mentors multi-disciplinary teams with clarity and technical depth.
  • Cross-Functional Collaboration : Works effectively with hardware, software, mechanical, and systems engineering teams.
  • Customer Focus : Strong system-level thinking with sensitivity to application requirements and product value.
  • Innovation Mindset : Drives continuous improvement, patent generation, and competitive differentiation.
  • Decision-Making : Balances risk, performance, and timeline in high-impact technical decisions.
  • Communication : Strong verbal and written communication to present architectures, trade-offs, and strategy to execs and peers.
