Responsibilities

Own schematic design, component selection, and PCB development for embedded control and power electronics; guide layout and bring-up and perform board-level validation.
Architect electromechanical subsystems (motors, transformers, pumps, fans, heaters) including drivers, sensors, protections, thermal management, and firmware interfaces to microcontrollers.
Develop prototypes to de-risk concepts; execute feasibility, EVT/DVT/PVT test phases; iterate based on performance, reliability, and manufacturability.
Create comprehensive test plans and scripts; conduct bench, environmental, and regulatory pre-compliance evaluations; analyze results and drive corrective actions.
Ensure products meet applicable safety and performance standards (e.g., UL/ETL/CSA/IEC) and consumer appliance norms, support Project Engineers during formal agency testing.
Produce and maintain design documentation: product requirements, design reports, DFMEA, DVP&R, test methods, and lessons learned.
Partner with Project Engineers, Mechanical Design Engineers, Software Engineers and other cross-functions; translate consumer insights into engineering specifications; present technical findings to mixed audiences.
Work with OEM/ODM partners on design for manufacturing (DFM/DFA), pilot builds, reliability testing; travel to supplier sites as needed.
Lead cost-down and value engineering initiatives on existing products without compromising safety or performance.
