POSITION SUMMARY

VanSpeag Group LLC is partnering with a leading high-technology engineering, design & development firm to identify and place highly skilled Electrical Engineers specializing in DC to DC power conversion, high-frequency switching systems, and contactless wireless power transfer (WPT) technology. These roles span multiple experience levels and will support the design, development, test, and integration of advanced power electronics solutions-including resonant inductive wireless charging systems-for mission-critical applications across automotive, industrial, defense, and consumer markets.

This is a rare opportunity to join a dynamic engineering organization working at the intersection of power density, efficiency, wireless energy delivery, and next-generation platform development. Engineers in these roles will contribute to both conventional switched-mode power supply design and cutting-edge long-range, high-power wireless charging systems capable of delivering milliwatts to kilowatts of power without physical contact-enabling complete operational autonomy across extreme environments. VSG will work closely with each candidate to match skill set, career goals, and compensation expectations to the right-fit opening.

KEY RESPONSIBILITIES

Design, simulate, and develop DC/DC converters including buck, boost, buck-boost, flyback, LLC resonant, and full-bridge topologies

Develop and optimize switching power supplies operating in the KHz to MHz frequency range

Perform power loss analysis, thermal modeling, and efficiency optimization across full operating range

Select and evaluate magnetic components (inductors, transformers, coupled inductors) for high-frequency operation

Lead PCB layout reviews for EMI/EMC compliance, signal integrity, and thermal management

Conduct bench-level hardware bring-up, debug, and characterization of prototype power stages

Develop control loop designs (voltage mode, current mode, digital control) and compensation networks

Support gate driver design, dead-time optimization, and switching waveform analysis

Prepare design documentation, technical specifications, and peer review materials

Support qualification testing, FMEA, and design verification/validation activities

Mentor junior engineers and contribute to design review culture (Senior/Staff/Principal levels)

Design and optimize resonant inductive wireless power transfer (WPT) systems, including transmitter and receiver coil topology selection, compensation network design (series-series, series-parallel, LCC, LCCL), and resonant frequency tuning for milliwatt- to kilowatt-class applications

Develop RF amplifier and inverter circuits (Class D, Class E, Class EF) to drive WPT transmitter coils at operating frequencies ranging from 100 kHz to 13.56 MHz and above

Model and simulate electromagnetic coupling coefficients, mutual inductance, and quality factor (Q) for air-core and ferrite-core coil designs using ANSYS Maxwell, COMSOL Multiphysics, or equivalent FEA tools

Design and validate electromagnetic shielding and magnetic flux management strategies to minimize EMI and meet FCC, CE, and applicable regulatory standards for radiating wireless power devices

Develop adaptive impedance matching and frequency-agile control algorithms to maintain high end-to-end power transfer efficiency across variable airgap distances and load conditions

Characterize WPT system performance metrics including end-to-end efficiency, power delivery at distance, misalignment tolerance, and thermal behavior of transmitter and receiver electronics

Support integration of foreign object detection (FOD) and living object protection (LOP) safety circuits into WPT system architectures for automotive, industrial, and defense deployments

REQUIRED QUALIFICATIONS
