Hardware Engineer (AC IoT)

Role Summary

This role is mainly working on the continuous expansion of our USL/UC product portfolios — covering IoT / light switch / AC-side smart devices, IoT sensors, and UC display platforms.

You will independently drive products from design to mass production, owning board-level design, certification, and EMS/ODM technical execution.

You will serve as our dedicated technical window with manufacturing partners to resolve issues efficiently across the full EVT → DVT → PVT → MP cycle.

Responsibilities (What he/she will do after joining UI)

– AC-Side Product Design: Hands-on experience designing smart relays, light switches, dimmers, or smart plugs — including live/neutral line handling, isolation design, and creepage/clearance compliance.

– Define power architecture and conduct battery life estimation for primary lithium (CR series) and rechargeable Li-ion applications.

– Drive low-power optimization through µA-level current measurement, sleep / wake-up strategy design, and power budget planning.

– Design and review PMIC, charger IC, and battery protection circuits to ensure product safety and reliability.

– Integrate wireless connectivity solutions (BLE, Zigbee, Wi-Fi, or Sub-GHz) into product designs, including SI and antenna tuning.

– Lead EMC / ESD debug and bring products through regulatory certification independently.

– Serve as the dedicated technical interface with EMS / ODM partners for NPI, mass production ramp-up, and ongoing yield improvement.

– Partner with firmware, mechanical, QA, and PM teams to deliver products that meet design, schedule, and quality targets.

– Mentor junior engineers and share best practices on low-power design, battery products, and factory-side execution.

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.

– Proven experience with battery-powered portable products, including both CR primary discharge and Li-ion applications.

– Solid expertise in low-power design, including µA-level current measurement and battery life estimation.

– Strong proficiency in PMIC, charger IC, and battery protection circuit design.

– Hands-on experience with at least one wireless protocol (BLE, Zigbee, Wi-Fi, or Sub-GHz).

– Hands-on EMC / ESD debug experience, with the ability to lead products through certification independently.

– Practical experience collaborating with EMS / ODM factories, including NPI, mass production, and yield improvement.

– Familiarity with IoT, lighting, or other control-related designs (basic understanding of AC circuits is sufficient).

– Strong cross-functional communication skills with firmware, mechanical, QA, and PM teams.

Preferred Qualifications

– AC-Side Product Design: Hands-on experience designing smart relays, light switches, dimmers, or smart plugs — including live/neutral line handling, isolation design, and creepage/clearance compliance.

– Tablet & Smartphone Hardware: Board-level design experience covering display interfaces, touch panels, and battery systems — directly applicable to our UC display product roadmap.

– IoT Sensor Design: Proven track record designing PIR, door/window contact, temperature/humidity, or motion detection modules for IoT applications.

– ESD / Surge / EMC Debug: Direct, hands-on experience diagnosing and resolving pre-compliance or certification failures — not just familiarity with the standards.

– RF & Wireless IoT: Solid understanding of at least one wireless protocol (Wi-Fi, BLE, Zigbee, Z-Wave, or Sub-GHz), including antenna placement rules, RF layout guidelines, and co-existence handling.

– ODM/EMS Factory Collaboration: Practical experience managing NPI deliverables and resolving technical issues with manufacturing partners across the full EVT → DVT → PVT → MP cycle.
