LED SMART INC 诚招Junior Electronics Hardware Engineer

Position Overview

LED Smart Inc. develops electronic products for lighting, sensing, and control applications. We are seeking a hands-on junior electronics hardware professional to maintain existing products and gradually contribute to new product development. Under the technical guidance and design review of a senior hardware specialist, you will diagnose circuit and PCB failures, update Altium design files, validate changes, and support production.

Initial focus: Your priority will be existing-product maintenance, failure investigation, repair, technical documentation, and production support. As your product knowledge grows, you will take on circuit modifications, component selection, prototype bring-up, and new hardware development.

Key Responsibilities

Troubleshoot, diagnose, repair and test electronic circuits, assembled products and printed circuit boards (PCBs).

Reproduce reported problems, perform component-level failure analysis and identify root causes under appropriate technical guidance.

Maintain and revise schematics and PCB layouts exclusively in Altium Designer, including approved changes to existing products.

Maintain bills of materials, engineering-change records, manufacturing files and test procedures; help evaluate replacements for obsolete or unavailable components.

Perform prototype assembly, soldering, board modifications and SMT/through-hole rework.

Use oscilloscopes, multimeters, power supplies, electronic loads and related laboratory equipment to characterize and debug hardware.

Assist with analog, digital, mixed-signal and power circuit modifications, component selection and design calculations.

Work safely with AC/DC and mains-powered circuits and support EMI/EMC troubleshooting using established laboratory procedures.

Work with production personnel to resolve manufacturing issues, improve testability and introduce prototypes into production.

Clearly document test setups, results, repair procedures, root-cause findings and hardware changes.

Preferred Qualifications

Experience with switching power supplies, AC/DC or DC/DC converters, LED drivers, inverters or related power electronics.

Exposure to microcontrollers, embedded hardware and interfaces such as UART, I2C, SPI, RS-485, CAN or Ethernet.

Exposure to EMI/EMC troubleshooting, product-safety testing or regulatory requirements such as UL, CSA, FCC or ISED.

Experience with PCB manufacturing, production testing, design for manufacturability or design for test.
