- 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
