About the Job

Requirements

  • A bachelor's degree or higher in electronic engineering, automation, communication engineering, computer engineering, or a related major.
  • Experience designing and developing embedded hardware products.
  • In-depth understanding of 8-, 16-, and 32-bit microcontroller architectures and substantial application experience with mainstream general-purpose microcontroller brands.
  • A solid foundation in analog and digital circuit design, including filters, logic-level conversion, and transistor switching.
  • Familiarity with electrostatic-discharge protection, surge protection, and isolation techniques.
  • Proficiency with at least one mainstream electronic design automation tool for schematic and printed circuit board layout design; Altium Designer, Cadence Allegro, or PADS is preferred.
  • Ability to operate standard laboratory instruments, including oscilloscopes, logic analyzers, multimeters, and regulated power supplies.
  • Good hand-soldering ability for prototyping and surface-mount component repair.
  • Good spoken and written Mandarin Chinese.
  • Good spoken and written English.

Responsibilities

  • Define and design embedded-system hardware architectures, evaluating and selecting general-purpose microcontrollers based on processing capability, input/output count, peripherals, and cost.
  • Independently design circuit schematics and apply printed circuit board design fundamentals to ensure signal integrity, power distribution, and thermal management.
  • Use microcontroller resources such as analog-to-digital converters, digital-to-analog converters, pulse-width modulation, and timers to design reliable interface circuits.
  • Implement and optimize communication interfaces and buses, including Universal Asynchronous Receiver/Transmitter, Inter-Integrated Circuit, Serial Peripheral Interface, Controller Area Network, and RS-485.
  • Design reliable power trees using DC-DC converters and low-dropout regulators to provide stable, low-noise power to microcontrollers and peripheral components.
  • Bring up hardware boards, measure signals, and troubleshoot faults; collaborate closely with firmware engineers to verify hardware functionality and peripheral drivers.
  • Perform hardware validation and environmental testing, and investigate electromagnetic compatibility and electromagnetic interference issues to ensure product reliability and regulatory compliance.

Desired Qualifications

  • Ability to use microcontroller development environments such as Keil, IAR, or STM32CubeIDE to write basic C code for initial hardware verification and testing.
  • Experience designing low-power hardware or battery-powered systems.
  • Experience developing external memory interfaces such as EEPROM and Flash, and display interfaces such as OLED and LCD.
