Hardware Product Manager - Smart Ring

We are building a next-generation smart ring that combines health and fitness tracking with a press-to-record voice feature. This role owns hardware execution end to end, working closely with ODM/CM partners.

Responsibilities

• Own the smart ring hardware system and electrical architecture:

  • BLE SoC / MCU

  • PPG, IMU, temperature sensors

  • Microphone and audio front end

  • Battery, PMIC, and wireless charging

• Work directly with ODM engineers on schematics, PCB layout, and design trade-offs (size, power, RF, cost).

• Lead power, RF, and sensor performance validation in real-world use.

• Bring up and debug EVT/DVT prototypes; troubleshoot power, RF, sensor, and audio issues using lab tools.

• Drive fast design iterations while ensuring DFM/DFT readiness.

• Define hardware test coverage for EVT/DVT/PVT and review factory test fixtures and processes.

• Support NPI, analyze build data, and drive fixes through to mass production.

• Act as the China-side hardware owner, keeping HQ and factories aligned on risks, decisions, and timelines.

Requirements

• 5+ years of consumer electronics hardware experience, ideally wearables or small devices.

• Strong in low-power BLE systems, mixed-signal design, and battery-powered products.

• Hands-on with bring-up, debugging, and prototype validation.

• Experience working with China-based ODM/CMs and EVT/DVT/PVT cycles.

• Able to work closely with firmware teams and understand HW/FW trade-offs.

Nice to Have

• PPG or health wearable experience.

• Microphone and audio chain experience in small form-factor devices.

• Smart ring, TWS, or jewelry-class electronics background.

• Mandarin and English proficiency.
