Job description

Human Resource - Global Strategic Talent Acquisition - Larsen and Toubro. | Semiconductor | Digital | IT Leadership Hiring.

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:

• Expertise in wide-bandgap semiconductors (SiC/GaN) and digital power 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.
