About the Job

Requirements

A Bachelor's or Master's degree in Electrical Engineering or a related field, with a strong academic focus on power electronics.
Direct experience designing AC/DC or DC/AC power converters through industry internships, senior design projects, or thesis research.
Proficiency with circuit simulation tools such as PSIM, PSpice, or LTspice.
Hands-on skill using an oscilloscope for signal integrity and power-stage debugging.
Proficiency with soldering irons for component replacement and printed circuit board modifications.
Ability to interpret complex waveforms and translate data into actionable design improvements.

Responsibilities

Assist in designing and developing power converter products, including AC-to-DC rectifiers/power factor correction systems and DC-to-AC inverters.
Perform hands-on printed circuit board assembly soldering using surface-mount and dual in-line package techniques, and assemble hardware for prototype units.
Use oscilloscopes, power analyzers, and other laboratory equipment to verify circuit performance and capture electrical waveforms.
Analyze switching waveforms to identify design issues such as voltage spikes, ringing, or thermal inefficiencies.
Troubleshoot hardware failures and design flaws by correlating physical measurements with theoretical calculations to identify root causes.
Prepare technical reports, test plans, and bills of materials documentation.

Desired Qualifications

Knowledge of magnetic component design, including transformers and inductors.
Familiarity with digital control implementation using microcontrollers or digital signal processors.
Basic understanding of electromagnetic interference/electromagnetic compatibility suppression techniques and safety standards such as UL, IEC, and CE.
