Role Overview

The Embedded Hardware Design Engineer will be responsible for the design, development, prototype bring-up, debugging and validation of embedded hardware for power electronic products.

Key Responsibilities

  • Design and develop power electronics hardware such as DC-DC converters, battery chargers, inverters, PFC and related control electronics.
  • Design analog, digital and microcontroller-based circuits, including voltage/current sensing, protection and signal conditioning.
  • Select and validate MOSFETs/IGBTs, gate drivers, inductors, capacitors and other critical components.
  • Develop schematics and support PCB layout, design review and prototype manufacturing.
  • Bring up prototype boards and perform hardware debugging using oscilloscope, DMM, electronic load, power supply and other laboratory equipment.
  • Analyze switching waveforms, gate-drive signals, current/voltage feedback and power-stage performance.
  • Debug hardware issues and identify the root cause of failures, including component, layout, noise and thermal-related problems.
  • Work closely with embedded firmware engineers for PWM, ADC, CAN, protection and control implementation.
  • Perform hardware validation for efficiency, thermal performance, protection functions and operating limits.
  • Support EMI/EMC troubleshooting and design improvements.
  • Prepare schematics, BOM, design documents and test reports.
  • Support production issues, component qualification and engineering changes.

Required Skills

  • Good understanding of power electronics and switching converters.
  • Hands-on experience with MOSFET/IGBT, gate drivers, current/voltage sensing and protection circuits.
  • Experience with STM32, TI C2000 or similar microcontrollers.
  • Good knowledge of ADC, PWM, CAN, SPI, I²C and UART.
  • Experience with schematic and PCB design tools such as Altium, OrCAD or KiCad.
  • Strong practical experience with oscilloscope and hardware debugging.
  • Basic understanding of EMI/EMC, grounding, filtering and PCB layout practices.
  • Ability to read datasheets and perform basic power-stage and component calculations.

Preferred

  • Experience in EV, automotive, battery, motor controller or high-power DC-DC applications.
  • Experience with SiC/GaN devices, isolated power supplies or high-frequency converters.
  • Exposure to LTspice, PLECS, MATLAB/Simulink or PSIM.
  • Experience with hardware validation and production support.
