Must have a professional experience with core material properties and their selection. Must be able to review related work completed by junior engineers. Must have the ability to roadmap transformer and inductor technologies as they pertain to the direction of future business.
    • EMI Filter design, analysis, test, and simulation considerations in power electronics circuits. Must be able to review related work completed by junior engineers. Must have the ability to roadmap EMI Filter design in power electronics circuits as it pertains to the direction of future business.
    • Analog electronics design, including all of the following: FET/BJT logic level, op-amp, high/low/band pass filters, clock/data termination, and comparator circuits, along with an understanding of how these circuits are utilized in power electronics. Must be able to review related work completed by junior engineers. Must have the ability to roadmap analog electronics design in power electronics circuits as it pertains to the direction of future business.
    • Conducting trade studies relating to power electronics architecture at the power system level. Must be able to review related work completed by junior engineers.
    • Guiding drafters through the ECAD process, including the layout and routing concerns specific to non-isolated and isolated power electronics. Must be able to review related work completed by junior engineers. Must have the ability to roadmap PCB design relating to power electronics circuits as it pertains to the direction of future business.
    • Designing at the power system level to meet concerns of adjacent disciplines, such as thermal, structural, mechanical, reliability, and quality.
    • Utilizing and creating electrical design specifications. Must be able to review related work completed by junior engineers. Must have professional experience with requirements definition early in the design cycle.
    • Leading larger teams, and experience working with other team leads toward a larger goal. Must have direct experience managing customer relationships.
    • Communicating and documenting technical topics at the small and large team level, and experience presenting to upper levels of management and customers.
  • The ability to obtain and maintain a U.S. security clearance. U.S. citizenship is required as only U.S. citizens are eligible for a security clearance.

Qualifications We Value:
  • In-depth professional experience with:
