POSITION SUMMARY
The Electrical Engineer is responsible for developing motor-control algorithms and advanced electrical systems that power high-speed rotating equipment. The role focuses on control strategies and embedded firmware for Variable Frequency Drives (VFDs) used with AC motors, DC motor controllers for DC motor applications, motor-control electronics, and the integration of industrial communication protocols. The engineer will own the firmware portion of the development and ensure robust, efficient, and reliable system performance through power-electronics expertise, modeling, simulation, testing, and validation. The position requires close collaboration with engineering, manufacturing, quality, sales, product management, and external suppliers to take designs from requirements and specification development through prototyping, validation, and full-scale production. The ideal candidate combines deep motor-control and firmware expertise with the ability to communicate technical requirements clearly to hardware-development partners and vendors.
