About The Position

As an Electromagnetics & High Frequency Power Electronics Engineer for General Dynamics Mission Systems, you’ll be a member of a cross functional team responsible for developing smaller, more efficient high voltage power supplies as part of our subsea communication systems.

Requirements

Bachelor’s degree in Electrical Engineering, or a related Science, Engineering, Technology or Mathematics field.
8+ years of job-related experience, or a Master's degree plus 6 years of job-related experience.
Department of Defense Secret security clearance is obtainable within a reasonable amount of time after hire.
Applicants selected will be subject to a U.S. Government security investigation and must meet eligibility requirements for access to classified information.
U.S. citizenship is required.
Electromagnetics Foundation: Maxwell's equations and their practical application to magnetics and parasitics.
Finite Element Analysis (FEA) for magnetic field simulation (ANSYS Maxwell, COMSOL) — essential for designing custom magnetics that perform as expected before hardware is built.
Understanding of dielectric behavior and electric field distribution in HV isolated design.
EMI/EMC analysis at high frequencies.
High Frequency Magnetics Design: Design custom high frequency power transformers for HV isolated applications.
Understand and manage core loss, copper loss, and thermal behavior at high frequencies.
Select and apply appropriate core materials (ferrite, nanocrystalline, amorphous) for target frequency ranges.
Design windings to mitigate skin and proximity effects.
Control leakage inductance and interwinding capacitance — parameters that are critical to both efficiency and isolation integrity in HV designs.
Resonant Circuit Design (LC Tank Circuits): Design and optimize LC tank circuits for resonant power conversion.
Understand the interaction between the transformer and the resonant network — these cannot be designed in isolation at high frequencies.
Tune resonant designs for zero voltage switching (ZVS) and zero current switching (ZCS) to minimize switching losses and maximize efficiency.
Analyze and manage frequency-dependent behavior across load and input voltage ranges.
5+ years with direct experience in high frequency magnetics design and resonant power electronics.
BSEE minimum.
