Sr. Staff System Engineer – Energy Generation, Storage & Conversion

We are seeking an experienced and visionary System Engineer to define and drive end-to-end solutions for energy generation, storage, and power conversion systems. This role bridges energy market requirements with semiconductor and power electronic capabilities to deliver next-generation infrastructure solutions supporting the transition to a sustainable energy ecosystem.

You will be responsible for designing scalable, efficient, and reliable energy system solutions, from grid interfaces and renewable energy sources (solar, wind) to battery energy storage systems (BESS), power conversion units, and local distribution setups.

The ideal candidate is a recognized technical leader with deep expertise in power topologies, grid compliance, and battery management. You will partner with product groups, platform teams, and executive leadership to co-develop innovative power systems, accelerate innovation, and shape cutting-edge semiconductor solutions for the global renewable energy, energy storage, and grid infrastructure markets.

Key Responsibilities

System Engineering & Design

• Define complete energy system designs, including grid connection and protection schemes (MV/LV).

• Develop AC/DC and DC/DC power conversion topologies (PFC, LLC, PSFB, bidirectional converters).

• Design Battery Energy Storage Systems (BESS), including advanced Battery Management Systems (BMS).

• Ensure microgrid control, islanding, and black start capabilities for distributed energy systems integrating solar PV, wind turbines, and fuel cells.

Power Conversion & Distribution

• Design bidirectional energy flows for charging/discharging storage systems and integrating them into local grids.

• Optimize system-level efficiency, power density, thermal performance, and lifetime reliability.

• Support the development of solid-state transformer-based systems for high-efficiency energy transfer.

• Ensure grid code compliance, safety, and reliability for all energy generation and storage systems.

Strategic & Cross-Functional Leadership

• Provide system requirement documents (SRDs), reference designs, and evaluation platforms for energy applications.

• Collaborate with utility operators, renewable developers, and storage OEMs to co-develop innovative power systems.

• Guide internal product teams, power IC designers, controls engineers, and thermal/mechanical experts to build fully integrated solutions.

• Track emerging standards, grid codes, and sustainability regulations across key markets to contribute to technical roadmaps and strategic positioning.

Education

• Master’s or Ph.D. in Electrical Engineering, Power Electronics, or a related technical field; OR a Bachelor's degree coupled with 10+ years of equivalent, highly relevant industry experience

Experience

• 8+ years of hands-on experience in energy generation, storage, and power conversion systems.

• Proven experience guiding cross-functional product and engineering teams.

Technical Skills

Deep expertise in:

• AC/DC and DC/DC power topologies (PFC, LLC, PSFB, bidirectional).

• MV/LV power distribution architectures and protection.

• Battery energy storage systems (BESS) and battery management.

Strong understanding of:

• Grid codes, interconnection standards, and renewable integration requirements.

Hands-on experience with:

• System-level modeling/simulation tools (PLECS, SPICE, MATLAB/Simulink, CFD).

Nice to Have

• Experience with energy metering and smart grid communication protocols (Modbus, IEC 61850, OCPP).

• Familiarity with EV charging station architectures (AC and DC fast charging) and vehicle-to-grid (V2G) integration.

• Expertise in wide-bandgap (SiC/GaN) power systems and solid-state transformers.

• Knowledge of energy orchestration frameworks, microgrid control, and digital twins.
