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. You will design scalable energy system solutions spanning grid interfaces, renewable sources, battery energy storage systems (BESS), and power conversion units.
What you'll do
- Define complete energy system designs, including MV/LV grid connection, protection schemes, and microgrid control with islanding and black start capabilities.
- Develop AC/DC and DC/DC power conversion topologies including PFC, LLC, PSFB, and bidirectional converters.
- Design Battery Energy Storage Systems (BESS) and advanced Battery Management Systems (BMS).
- Optimize system-level efficiency, power density, thermal performance, and lifetime reliability while supporting solid-state transformer-based systems.
- Provide system requirement documents (SRDs), reference designs, and evaluation platforms for energy applications.
- Collaborate with utility operators, renewable developers, storage OEMs, power IC designers, controls engineers, and thermal/mechanical experts.
What you'll need
- 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.
- 8+ years of hands-on experience in energy generation, storage, and power conversion systems.
- Deep expertise in AC/DC and DC/DC power topologies (PFC, LLC, PSFB, bidirectional) and MV/LV power distribution architectures and protection.
- Deep expertise in 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 including PLECS, SPICE, MATLAB/Simulink, or 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.
