### Power IC Design & Review
- Design and review PMIC, charger IC, and battery-protection circuits to ensure product safety and reliability. Requirement (Must-Haves)
- Bachelor’s degree in Electrical Engineering, Electronics, or a related field. - 10+ years of hands-on hardware design experience in consumer electronics or IoT products.
- Power-electronics / AC-side product design experience — a proven track record taking AC-powered products (smart relays, light switches, dimmers, or smart plugs) to mass production, including AC-DC conversion, live/neutral handling, isolation design, and creepage/clearance (safety) compliance.
- Hands-on EMC / ESD debug experience, with the ability to lead products through certification independently.

### Advanced Power Electronics
- Deeper experience with switching topologies (buck / flyback / PFC), transformer & magnetics design, phase-cut / TRIAC dimming, and energy-metering ICs. - PMIC / Charger IC / Protection: PMIC, charger IC, and battery-protection circuit design.

### Surge / Lightning / EMC for AC Products
