Sr. Staff System Engineer – Energy Generation, Storage & Conversion
Originally posted 10 November 2026 by the employer.
About the role
This role defines and drives end-to-end solutions for energy generation, storage, and power conversion systems, bridging energy market requirements with semiconductor and power electronic capabilities. The scope spans grid interfaces, renewable sources, battery energy storage systems (BESS), power conversion units, and local distribution architectures.
What you'll do
- Define complete energy system designs, including grid connection and medium-voltage/low-voltage (MV/LV) protection schemes.
- Develop AC/DC and DC/DC power conversion topologies such as PFC, LLC, PSFB, and bidirectional converters.
- Design Battery Energy Storage Systems (BESS), including advanced Battery Management Systems (BMS).
- Support microgrid control, islanding, and black start capabilities for distributed energy systems integrating solar PV, wind turbines, and fuel cells.
- Generate system requirement documents (SRDs), reference designs, and evaluation platforms for energy applications while guiding power IC designers and controls engineers.
- Ensure grid code compliance, safety, efficiency, power density, thermal performance, and lifetime reliability across energy generation and storage setups.
What you'll need
- Master’s or Ph.D. in Electrical Engineering, Power Electronics, or a related field, or a Bachelor's degree with 10+ years of equivalent industry experience.
- 8+ years of hands-on experience in energy generation, storage, and power conversion systems.
- Technical expertise in AC/DC and DC/DC power topologies including PFC, LLC, PSFB, and bidirectional converters.
- Expertise in MV/LV power distribution architectures, protection schemes, BESS, and battery management systems.
- Demonstrated knowledge of grid codes, interconnection standards, and renewable integration requirements.
- Hands-on experience with system-level modeling and simulation tools such as PLECS, SPICE, MATLAB/Simulink, or CFD.
Nice to have
- Experience with energy metering and smart grid communication protocols, including Modbus, IEC 61850, and 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.
