嵌入式软件开发工程师

Responsibilities

• Focus on firmware (FW) development, including low-level driver development and application-layer module implementation for Siemens PLC products.
• Deeply participate in full product lifecycle management, undertake core work such as technical solution design and key module development, and drive high-quality delivery from requirements to mass production.
• Apply expertise in embedded software engineering and Agile/DevOps practices to create continuous customer value through Siemens products.
• Ensure compliance with industrial product information security standards throughout the development process.

Must Have

• Bachelor's degree or above in Electronic Engineering, Computer Science, Automation, Mathematics, or a related engineering field.
• 3+ years of embedded software development experience, with hands-on experience on ARM Cortex-M/A series platforms, and familiarity with task scheduling, memory management, interrupt mechanisms, and real-time tuning of mainstream RTOS such as FreeRTOS, Zephyr, and Real-Time Linux.
• Solid knowledge and practical experience in real-time application development, driver development, and communication protocols (e.g., TCP/IP, SSL) for embedded systems.
• Familiarity with modern software development methods, including Clean Code, Test-Driven Development (TDD), static code analysis, and unit testing.

Preferred

• Experience in deep development of industrial real-time Ethernet protocols is preferred, including porting and debugging of protocol stacks such as PROFINET IRT, EtherCAT, Modbus TCP/RTU, and S7 communication.
• Experience with industrial automation systems (e.g., motion control, PID control, expansion modules) is preferred.
