  • Experience using tools such as MATLAB, MathCAD, Mathematica, or other similar tools. This includes experience developing templates with these tools.
  • Experience utilizing and creating electrical design specifications.
  • Experience with designing at the circuit card stack level to meet concerns of adjacent disciplines, such as thermal, structural, mechanical, reliability, and quality.
  • Experience with Texas Instruments C-2000 family of microcontrollers, Microchip PIC controllers, VHDL, or real time operating systems. Ability to design Z-domain control systems without referring to the S-domain.
  • Experience with using CAN-bus, UART, and/or RS-422
  • 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:
  • Design, analysis, and simulation experience with at least one, and conceptual familiarity (professional experience preferred) with all of the following isolated converter topologies: flyback, half-bridge, full-bridge, forward, push-pull, resonant.
  • Experience with professional transformer and inductor design, analysis, test, and simulation considerations in power electronics circuits.
  • Experience with EMI Filter design, analysis, test, and simulation considerations in power electronics circuits.
  • A self-starter, a quick learner, be able to function in a dynamic environment, and have good time management skills.
  • Experience leading larger teams, and experience working with other team leads toward a larger goal.
  • Direct experience managing customer relationships.
  • Experience communicating and documenting technical topics at the small and large team level, and experience presenting to upper levels of management and customers.
  • Professional Experience with wide bandgap devices (SiC, GaN) in power electronics designs.
  • Professional Experience with circuit simulator SIMPLIS, and/or system simulator SABER.
  • Professional Experience with Mentor Graphics DxDesigner, and/or Hyperlynx.
  • Professional Experience with acting as a liaison between program and functional management in a cross-matrixed organization.
  • Professional Experience with military specifications.
  • Professional Experience with design considerations for voltages > 400V and/or power > 10kW.
  • Professional Experience with three-phase power systems, power factor control, and inverter/rectifier development.
  • Professional Experience with motor control development.
  • Professional Experience with program management tools such as Earned Value.
  • Professional Experience with proposal development.
