Responsibilities

• Design & Development: Assist in the design and development of power converter products, including AC to DC (Rectifiers/PFC) and DC to AC (Inverters) systems.
• Prototyping & Assembly: Perform hands-on PCBA soldering (SMD/DIP) and hardware assembly for prototype units.
• Testing & Measurement: Utilize oscilloscopes, power analyzers, and other lab equipment to verify circuit performance and capture electrical waveforms.
• Waveform Analysis: Conduct deep-dive analysis of switching waveforms to identify design issues such as voltage spikes, ringing, or thermal inefficiencies.
• Root Cause Analysis (RCA): Troubleshoot hardware failures and design flaws by correlating physical measurements with theoretical calculations to find root causes.
• Documentation: Prepare technical reports, test plans, and BOM (Bill of Materials) documentation.

Minimum Qualifications

• Education: Bachelor’s or Master’s degree in Electrical Engineering (EE) or a related field, with a strong academic focus on Power Electronics.
• Practical Experience:
• Direct experience in designing AC/DC or DC/AC power converters (either through industry internships, senior design projects, or thesis research).
• Proficiency in circuit simulation tools (e.g., PSIM, PSpice, LTspice).
• Technical Skills:
• Hands-on Mastery: Skilled in using an oscilloscope for signal integrity and power stage debugging.
• Soldering: Proficient with soldering irons for component replacement and PCB modifications.
• Analytical Mindset: Demonstrated ability to interpret complex waveforms and translate data into actionable design improvements.

Preferred Qualifications

• Knowledge of magnetic component design (transformers/inductors).
• Familiarity with digital control implementation using MCUs or DSPs.
• Basic understanding of EMI/EMC suppression techniques and safety standards (UL/IEC/CE).
