Key Responsibilities include: Design & Development Support the design and analysis of 3-phase inverters & other power electronics solutions such as rectifiers, DC-DC converters, active harmonic filters, induction heating supplies, or grid-connected converters. Support component selection for power semiconductors, magnetics, capacitors, resistors, and protection devices. Perform basic electrical calculations (losses, efficiency, thermal margins) and support advanced analysis including thermal modeling, derating, and efficiency optimization. Support the design and analysis of 3-phase inverters & other power electronics solutions such as rectifiers, DC-DC converters, active harmonic filters, induction heating supplies, or grid-connected converters. Support component selection for power semiconductors, magnetics, capacitors, resistors, and protection devices. Prototype Build & Testing Assist with prototype assembly, bring-up, and debugging in the laboratory and coordinate 3rd party testing if/as required Define and execute test procedures for functional, thermal, EMI/EMC, and performance validation. Collect, document, and summarize test data for product development project reporting. Interpret test results, identify root causes, and support implementation of corrective design changes. Assist with regulatory and standards compliance (UL, IEC, IEEE, CE, EMC, safety, seismic where applicable). Manufacturing & Documentation Support Assist with BOM creation, part substitutions, and engineering change documentation. Drive completion and implementation of sustaining engineering initiatives including Engineering Change Orders (ECOs). Maintain engineering documentation including schematics, test reports, and revision histories. Support transition from prototype to production, including BOM optimization and supplier coordination. Provide technical support to manufacturing and quality teams for released products. Support Design for Manufacturability (DFM) and Design for Assembly (DFA) activities. Produce documentation needed by manufacturing to build new or modified products. Cross Functional Collaboration Participate in cross-functional design reviews, project meetings, and formal product development processes. Work closely with firmware, mechanical, manufacturing, and applications engineers. Actively learn company design standards, safety practices, and regulatory requirements. Seek feedback and mentoring to build technical depth and engineering judgment. Other duties as defined by management Do you qualify? We are seeking: BSEE required, MSEE preferred or equivalent experience in Engineering or a related field 2-5 years of experience in engineering role within a manufacturing environment.
