Electrical Engineer

Electrical Engineer 4

The Power Electronics Engineer will be a key contributor to the MPCS (Modular Power Conversion System) product development team, supporting the design, validation, and continuous improvement of power electronics hardware used in utility-scale energy storage and power conversion applications. This position will provide hands-on technical expertise in Gate Driver Board (GDB), Power Board, and power module development, helping accelerate design maturity, prototype validation, and issue resolution throughout the product development cycle.

The engineer will work closely with electrical design, controls, validation, manufacturing, and supplier teams to improve product performance, reliability, and manufacturability.

The role is expected to contribute directly to: development and validation of power electronics hardware for next-generation MPCS products; design improvements to gate drive and power board circuitry to enhance system reliability and robustness; execution of laboratory testing, including switching characterization, double-pulse testing (DPT), thermal validation, and fault-condition testing; investigation and root-cause analysis of inverter, gate drive, and power module failures;

support of product releases by identifying risks, validating corrective actions, and improving design quality; technical collaboration with suppliers and contract manufacturers to ensure successful prototype and production builds; and achievement of project milestones by providing timely technical solutions to complex power electronics challenges. This position plays a critical role in helping the team deliver safe, reliable, and high-performance power conversion products while supporting schedule commitments and long-term product quality objectives.
