GENERAL PURPOSE OF THE JOB:

Directly adds tangible value to the organization by bringing modern power electronics related technologies, new concepts, circuit topologies, magnetic components design, and control schemes.  Provides strong technical leadership based on rigorous education/training, product development experience, and good track record. Provide technical mentoring to junior engineer and lab technicians. Strong individual contributions in the new product development, system architecture, circuit analysis, and product packaging related to modern precision SMPS power supplies are expected. Evaluate various power converter topologies to achieve optimal cost/ performance design tradeoff. Select/design and evaluate various power electronic components including controller (analog or digital), power switching devices (MOSFETs, IGBTs, and / or wideband gap devices), inductors, transformers, capacitors, current sense elements diodes, etc. to support power converter design. Conduct worst case analysis to establish that designs will function per specifications over the intended operating range. Ability to guide PCB designers and Mechanical Designer for developing UL compliant circuit boards and enclosures for successful operation in highly noisy environment.
