JOB DESCRIPTION: Embedded Systems Engineer (Lập trình Hệ thống Nhúng)
Job Responsibilities
Firmware Development: Design, develop, and test low-level firmware for embedded systems using C/C++ to ensure high performance and reliability.

Hardware Interfacing: Write drivers and implement communication protocols (I2C, SPI, UART, CAN, USB, Ethernet) to interface with various sensors, actuators, and peripheral hardware.

System Integration: Port and configure Real-Time Operating Systems (RTOS, such as FreeRTOS or Zephyr) or bare-metal code on microcontrollers (ARM Cortex-M series, ESP32, etc.).

Debugging & Troubleshooting: Use hardware debugging tools (Oscilloscopes, Logic Analyzers, JTAG/SWD debuggers) to diagnose and fix hardware/software integration issues.

System Optimization: Optimize code for memory constraints (RAM/Flash) and power consumption to meet strict hardware resource limitations.

Schematic Review: Collaborate with hardware engineers to review schematics and PCB layouts, ensuring design feasibility and recommending hardware modifications.

Testing & Validation: Develop and execute automated test scripts for unit testing and system-level validation to ensure compliance with product specifications.

Product Lifecycle: Support the product from initial concept, prototype development, and board bring-up to mass production and field maintenance.

Job Requirements
Education: Bachelor’s degree in Electronics/Telecommunications, Computer Engineering, Automation, or related fields.

Experience: 2–5+ years of experience in embedded firmware development.

Technical Skills:

Languages: Strong proficiency in C/C++.

Microcontrollers: Extensive experience with ARM Cortex-M, ESP32, STM32, or similar architectures.

Operating Systems: Experience with RTOS (FreeRTOS, ThreadX) or embedded Linux.

Tools: Proficient in using Logic Analyzers, Oscilloscopes, and IDEs (Keil, IAR, STM32CubeIDE, VS Code).

Version Control: Strong Git skills for team collaboration.

Hardware Understanding: Ability to read and interpret electronic schematics and datasheets.

Analytical Thinking: Logical mindset to solve complex timing-critical or hardware-dependent problems.

Communication: Ability to bridge the gap between software and hardware teams.

Benefits
Competitive Compensation: Attractive monthly salary + technical project bonuses + performance incentives.

Insurance: Full social, health, and unemployment insurance in accordance with local labor laws.

Professional Growth: Access to advanced training on new chip architectures, embedded Linux, or IoT security.

Work Environment: Well-equipped lab with high-end electronic testing instruments and modern development boards.

Stability: Long-term career progression in R&D, System Architecture, or specialized embedded software engineering.

Industry Keywords: C/C++, ARM Cortex, STM32, FreeRTOS, Firmware, Driver Development, UART/SPI/I2C, Debugging, IoT, Microcontroller.

Attributes: Detail-oriented, Analytical, Persistent, Technical, Collaborative, Meticulous.
